Какой электросчетчик выбрать для монтажа: обзор электросчетчиков

При проведении электромонтажных работ не обойтись без установки электросчетчика. Именно благодаря ему у нас в домах и квартирах организован учет электроэнергии. Современный рынок предлагает огромное количество разновидностей таких счетчиков, но на каком стоит остановить свой выбор?
Замена счетчика должна проводиться опытным электромонтером. Особенно этот вопрос актуален для тех, кто хочет заменить старый и отработавший свой срок электросчетчик и при этом не нарушить подачу электросети в доме, что часто бывает, если неправильно подключены провода.
Покупая счетчик на рынках, продавец старается продать модели подороже, утверждая, что они более качественные и удобные, но на самом ли деле это так?
Давайте разберемся.

Основные разновидности электросчетчиков

К основным видам относят:

1. Индукционные;
2. Электронные.

Первый тип — это привычные для нас старый вид электромеханических элетросчетчиков. Среди преимуществ можно выделить небольшую стоимость (в сравнении с новыми электронными моделями, где увеличен функционал и потребление электроэнергии) и более больший межповрочный интервал.

Второй тип — это новые электронные счетчики. Среди их преимуществ можно выделить:

• Высокий класс точности;
• Есть многотарифность;
• Компактность.

Такой электронный электросчетчик имеет возможность дифференцированного учета потребляемой электроэнергии. Это означает, что счетчик будет при многотарифной системе расчетов учитывать стоимость за электричество в ночное время по более низкому тарифу по сравнению с дневным.
Компактность такого оборудования тоже заслуживает внимания. Его легко установить в модульный щит на специальную DIN — рейку.
Такой прибор практически невозможно перекрутить и отмотать, как в старых моделях, а точность расчетов благодаря встроенной микросхеме более надежна и точна.

Кроме этих двух отличий видов счетчиков существует еще и другие:

• Однофазный;
• Трехфазный;
• Многотарифный;
• Двухтарифный;
• Однотарифный.

Правильный расчет параметров счетчика для монтажа необходимого электросчетчика должен исходить по и по номинальному току. Стандартный номинал для квартиры и дома составляет 80 А. Сюда входит общая максимальная суммарность всех подключаемых приборов к сети с учетом выделенной максимальной мощности для данного помещения

Мощность измеряется в ваттах, а необходимый номинальный ток в амперах.

Чтобы узнать какой рабочий ток на данном объекте или квартире необходимо всю суммарную мощность подключаемых электроприборов (так называемую установленную мощность) поделить на 220В. Результатом и станет потребляемый рабочий ток этого объекта в амперах. Счетчик же надо брать с номиналом на 10-20% больше полученного расчетного тока.
Счетчики могут быть как однотарифными так и многотарифными. Для получение максимальной экономии лучше ставить многотарифные, которые помогают сэкономить расход электроэнергии в разное время суток. Напоминаю, что в ночное время тариф на электроэнергию может быть меньше. При этом надо перезаключить договор с энергоснабжающей организацией о переходе на двухтарифную систему учета.
Также есть различие и по количеству фаз. Для квартир в основном устанавливают однофазные счетчики, а вот для частного дома или промышленного объекта, где к вводу могут быть подведены 3 фазы электроэнергии — трехфазные.
Стоит заметить, что в трехфазной сети 380В и три фазы. На входе электроэнергии на объект вместе с установкой защитных автоматов желательно устанавливать и УЗО (Устройство защитного отключения). Основной принцип действия УЗО заключается в измерение входящего и исходящего тока и в случае обнаружения утечки, УЗО полностью обесточивает всю сеть. Такое устройство обязательно должно быть установлено в загородном и многоквартирном доме.
Чтобы правильно определить какой именно электрический счетчик нужен, необходимо посмотреть сколько фаз в вашем доме или квартире. Говоря проще, нужно посмотреть сколько проводов подключено к вашему вводному автомату. Если обнаружен кабель с двумя жилами (ноль и фаза), то это однофазная сеть и для подключения вам необходим счетчик однофазный. Напряжение в таком счетчике составляет 220В, что должно быть указано на самом приборе.
Если вы увидели, что к вводному автомату идут 3 жилы, а четвертая подсоеденина к нулевой шине, то это говорит о том, что это трехфазная сеть и тут необходим трехфазный счетчик.
В некоторых ситуациях и только по разрешению сетевой организации в квартирах с 220В можно подключить трехфазный счетчик. В данном случае расчет будет верным, если будет задействована только одна фаза.

Способы монтажа электросчетчика в щит

По способу крепления в щите можно сделать выводы о приобретении того или иного прибора учета для квартиры или дома.
В зависимости от конструктивной особенности электрощита производится и его монтаж. Так возможно подключение на специальную DIN рейку или на специальную панель в щите.
Обычно такие учетные приборы устанавливаются внутри помещения, но бывает и на вводно — распределительных устройствах или же на улице.
Особенного внимания заслуживаем дата выпуска прибора учета. Так купив на рынке однофазный счетчик, который был выпущен более 2 лет назад, есть большая вероятность того, что инспектор, который будет его регистрировать попросту не поставит его на учет, а заставит его проверить в специалазирумой лаборатории или приобретать новый.
К трехфазным электроприборам этот срок еще меньше и составляет 1 год. Чтобы увидеть дату выпуска можно посмотреть на панель прибора и в паспорт (формуляр), который комплектуется с ним.
Если вы хотите установить ранее используемый электросчетчик для помещения, то на такой прибор должен быть документ о проведенной поверке данного прибора с давностью до одного года.

Стоит отметить, что, подключение электроэнергии в квартиру без правильно выбранного по типу счетчика с учетом даты его выпуска или поверки невозможно.

Как определиться класс точности электросчетчика?

После определения с фазами и типами электросчетчиков, максимального номинального тока, приступаем к выбору класса точности.
Чтобы понять это значение обозначает, то напомним, что
Класс точности это максимальная разрешенная погрешность, которая выражается в процентах.
Для квартиры этот показатель должен быть не хуже, чем 2. Чем выше класс точности, тем более точнее будут показания прибора. Имейте ввиду, что чем меньше цифра класса точности, тем точней прибор. Например, прибор с классом точности 1 более точен, чем с классом 2.
Имеются в продаже счетчики с классами точности:

Для гаража, квартиры или частного дома можно выбирать класс точности не более 2, а вот для магазина или автосервиса этот показатель не должен превышать 1.
В старых моделях можно встретить еще значение 2,5, но по-теперешнему законодательству использовать такие приборы учета не разрешают. Такие приборы требуют замены на более новые модели с необходим классом точности.
Еще один интересный вариант электросчетчиков — это приборы с разными тарифами. Основной смысл такого счетчика в наличии встроенных в него тарифных планов. Среди них бывают:

• Однотарифные;
• Двухтарифные;
• Многотарифные.

Двухтарифный счетчик работает в двух режимах с 700 до 2300, а после 2300 он переключается на ночной режим, который работает до 7 00 утра.
С наличием такого счетчика в квартире многие хозяева именно в период ночного тарифа начинают пользоваться стиральными машинками или обогревателями для дома.
Многотарифный счетчик имеет более двух встроенных режимов расчета.

При подключении электросчетчика стоит иметь ввиду, что при номинальной нагрузке больше 100А, подключение стоит проводить через трансформатор тока с имеющимся вторичным током в 5А.

Серия, модель и производители

Первым делом перед покупкой нужно узнать у сервисной компании электросети, какие производители и серии разрешены на установку в данном городе. Из полученного списка каждый может выбрать понравившуюся для себя модель и установить ее у себя.
Наиболее популярные модели электросчетчиков:

1. Нева;
2. Меркурий;
3. Энергомер.

Электросчетчик Нива 103 1SO.
Довольно удобный тип электромеханического счетчика, с барабанным типом циферблата. Очень надежный, цифры на счетчике всегда видны, даже если отсутствует сеть. Крепится на DIN рейку и имеет хорошую защелку. Имеет продуманную систему зажимов, которая гарантирует безопасную установку и снижает риск случайной поломки во время крепления.

Энергомер СЕ 101 —S6
Отличный вариант для установки энергосберегающими организациями.
Такой прибор имеет механический циферблат, а также возможность сохранять работоспособность при низких температурах. Крепится на трех винтах. Точные показания даже при сбоях в сети.

Счетчик Меркурий 231 АТ—01
Один из наиболее востребованных трехфазных электросчетчиков. Имеет встроенный интерфейс IRDA, что дает возможность дистанционного учета без взлома клеммной колодки. Есть 4 тарифных плана и 16 временных зон для качественного учета, журнал событий. Рассчитан только на внутреннее размещение.
Для однофазного энергопотребления, есть модель Меркурий 201.5. Имеет электромеханический циферблат с барабаном. Крепится на дин рейку. Есть также модели

Меркурий 201
Однофазный электросчетчик с цифровым циферблатом.

Подводя итоги

Какой электросчетчик выбрать для своего помещения, чтобы у него была максимальная продуктивность и не высокая стоимость? Для этого следует:

• Рассчитать максимальную номинальную мощность тока для данного помещения;
• Узнать сколько фаз в щите;
• Выбрать производителя;
• Выбрать класс точности;
• Определить тип эл. счетчика;
• Уточнить, как лучше его монтировать;
• Выбрать тарифность счетчика.

После получения этих данных стоит обратиться в компанию электросети, где получить все необходимые данные о разращенных производителях и сериях электроприборов.
После приобретения счетчика вызывается инспектор, который проверит показания старого счетчика с заполнением акта и даст разрешение на замену. Если все в порядке, то электромонтер проведет качественную установку данного прибора в соответствии с нормативными актами. После этого снова вызывается инспектор энергоснабжающей организации, который после проверки качества и соответствия выполнения электромонтажных работ по установке счетчика выдаст акт о проверке узла учета электроэнергии с записью показаний нового прибора и опломбирует узел учета.
При установке счетчика электроэнергии впервые на объект требуется сделать проект узла учета, утвердить его в энергоснабжающей организации, выполнить его монтаж и так же сдать учет, как описано выше.
Самостоятельно покупать, монтировать и проводить замену без согласования с компанией энергосбыта нельзя, так как это противоречит правилам учета энергии и грозит большими штрафами за не законное подключение к электросети.
И вот в конце обзора немного о том, стоит ли и кому стоит переходить на многоставочный тариф:

Take a note of the reading and the date when it was taken. If you can not find a pen and paper, take a photo using your smartphone.In the past, energy suppliers had to read your meter every two years, but this rule was scrapped in 2016. 90003 90002 90006 See other ways 90007 90006 save money on your energy bill 90007 90006. 90007 90003 90022 Is your energy meter faulty? 90023 90002 A Which? investigation (published in Which ?, March 2016) discovered that hundreds of thousands of gas and electricity meters in Great Britain could be faulty — meaning customers could be owed a lot of money. We’ve analysed Government figures, our own survey results and looked at confidential industry reports to investigate the scale of the problem.90003 90088 Meters running too fast or slow 90089 90002 Gas meters approved under UK law must be within 2% accurate and electricity meters within + 2.5% and -3.5% accurate. 90003 90002 Government figures show: 90003 90036 90037 On average, 24% of the gas meters tested every year since 2006 (21,243 meters tested in total) were faulty 90041 90037 7% of the 2,345 electricity meters tested since 2003 were faulty, installed incorrectly or not an approved type 90041 90067 90002 These are disputed gas and electricity meters — only tested because an error is already suspected — so the figures are not representative of Great Britain’s 53 million meter population as a whole.90003 90002 We’ve also seen three confidential National Grid reports that suggest the figures could be between 14% and 18%. National Grid said its figures were also not representative of the overall meter population. 90003 90104 90088 Meters telling the wrong time 90089 90002 There are 3.9 million households in Great Britain on a time-of-use tariff, such as Economy 7, which get cheaper electricity at certain times. 90003 90002 But we found that 16% of Which? members on one of these tariffs have found their meter clock is wrong (survey of 427 Which? members in Spring 2014 року).90003 90002 If that was true across the whole population, it would mean that 624,000 meters could be wrong. We’ve heard from people who have been overcharged hundreds of pounds due to this type of fault. 90003 90022 What to do if you suspect your gas meter or electricity meter is faulty 90023 90002 Unusual bills or meter readings are usually the best clue to a faulty meter. If you’re on a time-of-use tariff, you should be able to check the clock on your meter or see if the rate changes when it should.90003 90002 If you suspect your meter is faulty, then you should record regular meter readings to help prove your case. You could also try turning off all your appliances and watching the meter. It should not still be registering significant amounts of energy. 90003 90002 If you have a smart meter, the in-home display (IHD) that comes with it will also help show you how much energy you’re using in real-time. Like an energy monitor, the IHD is not a fool-proof way of checking meter accuracy, but it can be a helpful guide if you already have suspicions.90003 90121 90022 Your gas meter and electricity meter rights 90023 90002 Energy suppliers have a legal obligation to ensure all gas and electricity meters are accurate. If you suspect your meter is faulty, first contact your supplier — it is required to investigate. 90003 90002 Meters can be tested at your home or sent away to an independent laboratory. The actual testing is free but suppliers can charge for the cost of removing and replacing your disputed meter. Some reimburse the cost if the meter is found to be inaccurate.Find out more in our consumer rights guide to faulty meters. 90003 90022 Things you probably did not know about gas meters 90023 90002 Did you know you’ll probably get more gas for your money if you live at sea level rather than at the top of a mountain? And did you know you’re likely to get a better deal if your gas meter is outside? Here we look at how gas is really measured. 90003 90132 90088 Calorific value (CV) calculations 90089 90002 The calorific value — or heating value — of gas varies depending on where in the country you live.It also varies from day to day. The country is divided into 13 different charging areas (known as local distribution zones) and customers ‘bills are based on their area’s average daily calorific value for the billing period. 90003 90088 Temperature 90089 90002 Gas expands and contracts with heat. Bills are based on a temperature of 15 ° C. So those with meters outside can benefit, compared to those with meters inside. 90003 90088 Pressure 90089 90002 The volume of gas increases in low pressure.Bills are based on 1,013.25 mbar. So properties at a much lower altitude than average are likely to benefit. Billing assumes a height above sea level of 67.5m. 90003 90088 Postcode 90089 90002 Most consumers ‘bills will be slightly inaccurate because the assumptions about temperature and pressure are fixed for the whole country. An independent report produced for the Government shows that: in 2011 the postcode with the smallest error was PE11 (in Lincolnshire), and the one with the largest error was BD6 (Bradford).90003 90002 Assuming an average annual gas bill of £ 750, this is equivalent to under-billing of £ 11.77 and over-billing of £ 18.58. 90003 90151 90022 Economy 7 electricity meters 90023 90002 If you’re on an Economy 7 electricity tariff, you will have a special meter that provides two different readings: 90003 90036 90037 one for more expensive electricity used during the day 90041 90037 the other for cheaper night usage. 90041 90067 90002 For some Economy 7 meters, the higher rate will be displayed as ‘normal’ on your meter.Your cheaper night time rate will be displayed as ‘low’ on your meter. 90003 90002 If your meter is digital, Rate 1 will represent your cheaper night-time usage and Rate 2 your more expensive daytime usage. 90003 90002 Which? has discovered that many Economy 7 users may not be making the most of their tariff. If you use less than 30% of your electricity during your cheaper night time hours, then you might be better off switching to a single electricity tariff. 90003 90002 We also found that some people have Economy 7 meters with incorrect clocks, meaning they can not always make the most of their cheaper off-peak hours.Contact your energy supplier if you are unsure of your cheaper hours or think your meter clock is wrong. 90003 90022 Economy 10 and other electricity meters 90023 90002 Like Economy 7, Economy 10 meters give two different rates for electricity depending on the time of day. With Economy 10, you get 10 hours of cheaper electricity — usually overnight, mid-afternoon and late evening, when there’s lower demand. 90003 90002 In Scotland, these meters are often referred to as ‘white meters’. 90003 90002 90006 Find out more about Economy 7 and Economy 10 tariffs in 90007 90006 how to get the best energy deal 90007 90006.90007 90003 90184 90022 Prepayment energy meters 90023 90002 To use a prepayment meter, top-up before you can use your gas and electricity. 90003 90002 In the past you had to go to a shop to charge (add credit) to your card or key, or to buy tokens. You then inserted your charging device into the front of your prepayment meter. 90003 90002 Many energy companies now allow you to top-up remotely, via their website, app, or over the phone. This makes pay-as-you-go energy much more convenient than previously.90003 90002 90006 Find out: 90007 90006 is a prepayment energy meter right for me? 90007 90003 90002 The display window on the front of a standard pay-as-you-go meter can show a range of information including: 90003 90036 90037 Units of energy consumed 90041 90037 Any fixed charge the energy supplier charges 90041 90037 The rate per unit of fuel 90041 90037 The amount of credit inserted 90041 90037 Current credit 90041 90037 Any outstanding debt 90041 90037 Any debt repayments 90041 90037 Emergency credit.90041 90067 90002 When the energy meter runs out of credit, the gas or electricity supply is automatically stopped. However some suppliers now offer emergency credit so you’re not cut-off at an important time when you can not top-up. 90003 90002 Many energy firms are now installing smart prepayment meters. Read on to find out more. 90003 90022 Smart meters 90023 90225 90002 Smart meters enable energy suppliers to remotely record how much electricity and gas you’re using — doing away with the need for estimated bills and meter readings.The government is rolling out smart meters nationally by the end of 2020. 90003 90002 Your energy company will contact you to arrange installation of a smart meter. 90003 90088 Smart meters acting dumb 90089 90002 Sometimes smart meters can not send automatic readings back to your supplier and start acting ‘dumb’. This was the joint most-experienced problem by Which? members with smart meters when we surveyed them in November 2017. 90003 90002 Smart meters can lose their smart functions if: 90003 90036 90037 You switch to a supplier which can not operate your meter in smart mode 90041 90037 Technical problems 90041 90067 90002 Increasing numbers of energy companies are able to operate each others ‘smart meters.And by the end of 2020 року, the government intends to have a solution so that all meters are inter-operable between energy companies. 90003 90002 This could be due to technical problems. For example, the meter being unable to communicate externally or customers switching to a supplier that can not operate the meter in smart mode. 90003 90002 90006 Find out what the smart meter roll-out will mean for you, and if your energy supplier is installing them yet in our guide to the 90007 90006 smart meter roll-out 90007 90006.90007 90003.90000 You Have Insufficient Privilege To Read This Law At This Time 90001 You Have Insufficient Privilege To Read This Law At This Time The Logo of Public.Resource.Org The logo features a black and white line drawing of a smiling seal with whiskers.

Blondel, actually traces its origins back to 1893 when the engineer and physicist established the basic rules for metering alternating current circuits.Simply put, Blondel’s Theorem states that one less stator than the total number of wires in the circuit is required to correctly meter the energy flowing in the circuit. Under this rule, a two-wire circuit requires a single stator meter, a three-wire circuit requires a two-stator meter, and so forth. 90004 90002 The 0.1, 0.2, and 0.5 accuracy class electricity meters established within ANSI C12.20-2015 are accurate to within +/- 0.1%, +/- 0.2%, and +/- 0.5% of true value at a full load , respectively.Beyond the designations of these three meter types, the standard covers voltage and frequency ratings, test current values, service connection arrangements, pertinent dimensions, form and display designations, environmental tests, and acceptable performance of the meters and associated equipment. 90004 90002 It should be noted that Blondel’s Theorem is not strictly adhered to in all metering practices. For reference, non-Blondel metering installations are listed in Table 2A of ANSI C12.20-2015, and these explicitly are not covered by the standard.90004 90002 In fact, the clarification that non-Blondel applications are not covered by the document is one of the significant changes made to the new revision. Including this alteration, the updates made to the standard were made to keep it modern with an industry that is facing dramatic changes driven by advancements in technology and regulatory matters. Additional major changes to ANSI C12.20-2015 include testing under harmonic conditions, the addition of a 0.1% accuracy class, and the addition of specifications for the optical test output port.90004 90002 ANSI C12.20-2015 — Electricity Meters — 0.1, 0.2, and 0.5 Accuracy Classes is available on the ANSI Webstore. 90004.90000 Cycling power meters: explore these 24 systems to find the best one for you 90001 90002 90003 Over the last few years using a power meter to measure your training effort has more and more popular. Power meters have become cheaper as new manufacturers have entered the fray and there are more tools available to help you train with power. With meters now available for as little as £ 149, is it time to power up? 90004 90005 90006 90007 90002 Power meters use electronic strain gauges to measure how much force you’re putting into the bike and from that calculate your power 90005 90010 90007 90002 Cranks and pedals are the components most often used to house a power meter, but you can get power-measuring hubs, power meters that measure air flow and even a power meter valve cap 90005 90010 90007 90002 You’ll need a bike computer to record data from your power meter; almost all power meters use ANT + for communication, some also use Bluetooth which you’ll need if you want to use, say, Strava on a phone to record your data 90005 90010 90007 90002 The latest power meters need recalibrating less often than was the case a few years ago and are easier to install and set up, but it’s still worth thoroughly reading the manual 90005 90010 90023 90024 24 power meters — your power training options for 2020 90025 90024 What is a power meter anyway? 90025 90002 When you ride a bike, you do work to overcome the forces of air resistance, gravity and tyre rolling resistance.Power is the rate at which you work, so the more power you can put out, the faster you’ll go. And after all, that’s the objective of training. 90005 90002 The problem is, many things affect how fast you go, so it’s hard to monitor your progress. Even if you test yourself on the same course every time, variables like the weather can make a difference. 90005 90002 This is less of a problem in other sports. Swimmers, for example, can use timed laps of the pool to measure their fitness, as the resistance of the water is more or less a given.Runners can similarly assess their training progress by measuring pace on a track. 90005 90002 Faster! (CC BY-SA 2.0 Dennis van Zuijlekom) 90005 90002 Measuring your power output gives you a way to directly measure your fitness. A power meter is a device that does just that. 90005 90002 A complete power meter system has two parts: the measurement device itself and a handlebar-mounted ‘head unit’ that reads your current power and stores ride data for later analysis. Power meter manufacturers make head units, or you can use a bike computer such as a Garmin GPS that has the capability to work with a power meter.90005 90024 Why use a power meter? 90025 90002 Coach and training with power advocate Joe Friel calls a power meter «the most effective tool you can get to go faster on a bike». Because a power meter measures how hard you’re working it enables you to train very precisely, and to measure your progress. 90005 90002 Before power meters became popular, cyclists relied on heart rate as a proxy for training effort. But heart rate can be affected by more than just how hard you’re working, and the objective of training is not just to develop your heart.Rather, you’re aiming to go faster, and that means, all else being equal, generating more power. It’s therefore more efficient to measure power. 90005 90002 It can also save you time. Friel points out that it can take time to get up to a target heart rate even though you’re working as hard as you need to in a training session. With a power meter you can tell instantly that you’re putting out your session’s target power and stay there. If you’re strapped for time, a power meter lets you get the most out of your limited training hours.90005 90024 Types of power meter 90025 90002 Power meters use tiny electronic devices called strain gauges to measure the force you’re exerting on part of the bike’s transmission. From those raw measurements, supporting electronics calculate your power, which is then transmitted to the head unit, usually by a low-energy small area wireless protocol such as Garmin’s ANT + or Bluetooth. 90005 90002 Power meters have their strain gauges at different points in the path between your feet and the tyre that your effort travels along to propel you forward.The most common placements are in one or both pedals, one or both crank arms, in the chainring spider, or in the rear hub. 90005 90024 Crank meters 90025 90002 SRM crank (CC BY-NC-ND 2.0 by Kevin G Saunders: Flickr 90005 90002 The first widely-available power meter, from SRM, has its strain gauges in the crank spider, between the right hand crank and the chainrings. That means all the forces from both cranks go through the meter to be measured. 90005 90002 SRAM’s Quarq power meter and Pioneer’s system also have gauges in the crank spider, while PowerTap’s C1 chainrings move the measurement point one step along, but effectively do the same job.90005 90002 An alternative that allows for a less-expensive power meter is to measure the forces in the left hand crank. In theory this might give incorrect data as it’s only measuring the power from one leg, but in our tests the Stages Cycling power meter, which uses this design, gave readings consistent with a PowerTap hub meter and Garmin Vector pedals. Pioneer, whose cycling electronics business has been taken over by Shimano, also offers a left-hand-crank power meter. 90005 90002 A claimed advantage of power meters with the gauge in the crank arm is that they can be more accurate.The makers claim that the position of the gauge allows it to just measure the forces that propel you forward and not the twisting of the crank or other components. Verve Cycling takes this to its logical conclusion with its InfoCrank that has a measurement unit in each crank arm, and Rotor’s dual-sided system works similarly. 90005 90002 In the US, 4iiii will install its Precision power meter in your existing left-hand crank arm. 90005 90024 Bottom bracket 90025 90002 The only ‘universal’ bottom bracket power meter, from Ergomo, was available to fit square taper or Shimano Octalink cranks.It used wires to carry data to its own proprietary head unit, but was an inexpensive entry to power measurement if you had a set of older cranks to hand. 90005 90002 Rotor’s INpower also tucks the strain gauges and electronics into the crank axle, but you have to use Rotor cranks with it and similarly the Easton / RaceFace Cinch power meter measures power from the axle. 90005 90024 Pedals 90025 90002 Look and Garmin are the two longest-established manufacturers of power-measuring pedals. This design allows for easy swapping of the meter between bikes.Refinements to these pedals in the last couple of years mean that with the latest models it’s as trivial as just reaching for a pedal spanner. 90005 90002 Both Powertap and Favero also have pedal-based power meters. 90005 90002 Power-measuring pedals offer the ability to measure each leg’s power independently, and some are able to analyse your pedal stroke too. 90005 90002 On the same principal as left-crank meters, most pedal meter makers offer a single-pedal system that provides power data at lower cost.90005 90024 Rear hub 90025 90002 PowerTap hub (CC BY 2.0 Glory Cycles) 90005 90002 Measuring power in the rear hub must be fairly tricky, as PowerTap (since April 2019 owned by SRAM) remains the only manufacturer of a hub power meter, two decades years after introducing its first hub. Supported by relatively flexible frame ends, and hammered by road forces, the hub is a hostile place for delicate electronics, but PowerTap seems to have solved the problems. You can get a PowerTap hub either built into a wheel or a pair, or on its own so your favourite wheelbuilder can install your rim of choice.90005 90002 A hub power meter is the easiest type to switch between bikes, though if you want power readings while racing then you have to train on your racing wheels. Power meter advocates would say that’s a sensible decision. 90005 90024 All your power meter options 90025 90002 What follows is an overview of all the currently available power meters, that’s as comprehensive as we can make it. We kick off with the most recently announced models. 90005 90024 SRM Miche Attiva cranks — £ 1,249.00 90025 90002 A collaboration between SRM, who invented the power meter crank, and Italian component maker Miche, this is an attempt to make a power meter crank with SRM’s famed accuracy at a price that’s not out snuggling up to NASA’s Deep Space Climate Observatory. 90005 90002 It’s a curious beast though as it’s still not exactly cheap and at a claimed 945g it’s in the same weight range as some much, much cheaper competition. 90005 90002 Still, that’s an SRM power-measuring spider in there, so it should be accurate to ± 1.5% and go 100 hours between charges. 90005 90024 SRM X-Power SPD pedals — £ 939 90025 90002 File these under ‘not quite available yet’, but when you can actually buy them they’ll be the first dual-sided power meter pedals compatible with mountain bike-style two-bolt cleats. In fact, SRM say they’ll work with genuine Shimano SPD cleats: a big tick there for not trying to tie users in to a proprietary cleat. 90005 90002 SRM says the X-Power pedals electronics and strain gauges will be housed entirely inside the axle, along with a rechargeable battery that you charge with a little magnetic widget.On paper that could well make them tough enough for mountain biking and gravel bike use, as long as SRM gets the sealing right. And you’ll be able to swap out the pedal bodies for different colours if you buy a new bike and can not bear not to have matching pedals. 90005 90002 On the techier side of things, the X-Power pedals will feature: ANT + and Bluetooth comms protocols; matching apps for iOS and Android; 30 hours between charges; left / right balance; and claimed accuracy of ± 2%. 90005 90024 PowerTap Quarq P2 Pedals — ~ £ 610 90025 90002 PowerTap’s P2 pedals are an evolution of the P1 pedals from 2015 rather than a radical redesign.They are a claimed 34g lighter, now coming in at 400g a pair, and the battery life has been extended from 60 to 80 hours, using the same AAA battery. And that’s it, that’s all they’ve changed. Aside from the change from black to silver, there are no other significant changes. 90005 90002 There is the same ANT + and Bluetooth Smart compatibility, dual-sided power reading, Look KEO cleat interface, 2-year global warranty and 14mm stack height. 90005 90002 It’s a good bet that they’ll be functionally almost identical to the P1 pedals, which were very easy to set up and use.90005 90002 Since SRAM bought PowerTap in 2019, the PowerTap pedals have had ‘Quarq’ added to the name, SRAM’s power meter brand. 90005 90002 Read more about the PowerTap P2 pedals 90005 90024 Specialized Power Cranks — from £ 320 90025 90002 When Specialized launched the latest version of the Tarmac Disc, they also entered the power meter market with a range of meters, including two double-sided models based on Specialized’s own S-Works cranks and on the Shimano Dura-Ace cranks, and single -sided S-Works, Shimano Ultegra crank and SHimano 105 cranks.90005 90002 Specialized uses Canadian company 4iiii’s technology but did a whole bunch of its own development and testing with the Locomotion Lab in Boulder, Colorado to ensure the accuracy meets its claims. 90005 90002 The accuracy of each power meter it has developed is a claimed +/- 1.5% with temperature compensation firmware, and ANT + and Bluetooth are both supported for easy compatibility with many third-party devices. Specialized has also developed an app for setup and diagnostics. 90005 90002 The lightest setup, without chainrings, is the S-Works carbon dual-sided power crankset, which weighs a claimed 440g for a 172.5mm crank length. 90005 90002 Read more about the Specialized S-Works Power Cranks. 90005 90024 Look / SRM Exakt pedals — £ 1,269 90025 90002 Look’s latest power meter pedals are a collaboration with original power meter company SRM, which should be a winning combination of Look’s vast pedal expertise and SRM’s ability to create reliable power-measuring electronics. The external pods of previous Look power pedals are gone; everything is contained in the pedal’s carbon fibre body including rechargeable batteries that Look says give 100 hours of riding time.90005 90002 As well as the double-sided pedals linked above, there’s the inevitable £ 739 single-sided pedal that measures one side and doubles it, and a £ 1,949 bundle of the double-sided pedals with an SRM PC8 computer. 90005 90002 Read more about the Look / SRM Exakt pedals 90143 Find a Look dealer 90005 90024 IQ² crank / pedal interface power meter — NA 90025 90002 Announced in April 2018, the IQ² (say: IQ Square) power meter was supposed to sit between your cranks and pedals so there’d be no need to replace anything.It rapidly smashed its Indiegogo crowdfunding target; at the time of writing orders total well over £ 1.6 million. 90005 90002 The IQ² folks claimed some very clever manufacturing techniques help keep the price down and of course you would not be buying a crank or pair of pedals to get a power meter. Potential problems included the 32mm increase in the space between your pedals and the patchy history of crowdfunded power meter projects, many of which have started with claims of wonderful products and then collapsed in ignominy and unhappy customers.90005 90002 It was due to ship in November 2018, later put back to February 2019, and then on May 3 2019 the company announced that they were going to make complete pedals instead because they’d been unable to stop constant changes in the behaviour of the thread from influencing the readings. Downside: further delays. Upside: an SPD-style double-sided mountain bike pedal is promised along with a Keo-compatible road pedal. 90005 90002 As of May 12 2020 року, IQ² say they’ve actually shipped a single-sided pedal to a real customer, and they’ve also sent one to power meter guru Ray Maker at DC Rainmaker, who’s cautiously optimistic that IQ² will be able to produce a real, working power meter.But you still can not order it just yet. 90005 90002 Read more about the IQ² power meter 90005 90024 Team Zwatt Zpider cranks — ~ £ 410 90025 90002 The Zpider is a double-sided crank power meter based on an FSA Gossamer crankset. It comes without chainrings, but it’s compatible with Shimano four-bolt, 110mm BCD rings, so Team Zwatt is clearly assuming we all have a pair of those already, a reasonable assumption. 90005 90002 The Zpider has a built-in rechargeable battery with a claimed 240-hour life and magnetic charger.It communicates by ANT + and Bluetooth. 90005 90002 If weight’s important to you, there’s a carbon fibre version based on an FSA K-Force Light crankset for. 90005 90002 Read our first look at the Team Zwatt Zpider cranks 90005 90024 Giant Power Pro cranks — ~ £ 720 90025 90002 The Giant Defy Advanced Pro 0 and Liv Langma Advanced Pro 0 come with Giant’s Power Pro cranks, and you can also get them as a standalone item, though availability seems to be extremely limited at the moment. 90005 90002 Built, as you can see, into a Shimano Ultegra crankset, the Power Pro communicates with your bike computer via ANT + and can calculate pedalling angles and force and help you evaluate your pedalling efficiency.90005 90002 Read more about the Giant Power Pro cranks 90005 90024 Power2Max — from ~ £ 450 90025 90002 Power2Max makes power-measuring spiders to fit other manufacturers ‘crank arms, with varying degrees of functionality depending on how much you spend. 90005 90002 You can get the spider on its own if you have Rotor, SRAM, Cannondale or Specialized cranks, or get it the NG models installed in FSA, Rotor or Campagnolo cranks. 90005 90002 The three models for road bikes are: 90143 NG Road with claimed +/- 1% accuracy, ANT + and Bluetooth connectivity, and the ability to measure left / right balance, pedal smoothness and torque.90143 NGeco Road with claimed +/- 2% accuracy, ANT + and Bluetooth connectivity, and an optional firmware upgrade to measure left / right balance and pedal smoothness. 90143 Type S Road with claimed +/- 2% accuracy, ANT + connectivity, and left / right balance. 90005 90002 All three measure cadence too. 90005 90002 Read more about Power2Max power meters 90005 90024 Garmin Vector 3 pedals — £ 700 90025 90002 And the award for the most imaginatively-named new power meter goes to … 90005 90002 Joking apart, third time’s the charm for these pedals.Garmin has completely redesigned its Vector pedals, and the Vector 3 system is excellent. You get accurate power readings, they’re even easier to swap between bikes, they look much neater and they’re even a bit lighter. Add to that the fact that the RRP has dropped to £ 849.99 and they’re an enticing proposition. 90005 90002 The Vector 2 system’s weak point was the transmitter pod. It was an extra thing to remove and swap, and the connection was a bit fiddly, but most of all they were a bit prone to failure: I’ve had to buy at least two new ones, at £ 60 a pop.90005 90002 The Vector 3 is an entirely new design, and it does away with the pod completely. All the electronics are contained within the new pedal body. Everything has been redesigned: the electronics are new, of course, but so is the pedal body, and the axle, and the bearings. There’s really nothing left of the Vector 2. 90005 90002 These pedals transmit on ANT +, so you’ll be able to pair them up with your Garmin / Wahoo / [insert your GPS manufacturer here] head unit and get all your data. New for the Vector 3 is Bluetooth Smart connectivity.You do not get all the metrics that you get with ANT +, because the Bluetooth protocols do not support some of it. But it’s easy to get power and cadence on Bluetooth devices, and that could be really useful. 90005 90002 Benchmarked against a PowerTap hub and a Kickr smart trainer, the Vector 3s are consistent and accurate, and provide a serious nerdfest of data. 90005 90002 The Vector has really come of age with this redesign. It’s always been a good quality system with repeatable and accurate power measurement, but pretty much everything about the new pedals is an improvement.They’re probably the best power-measuring pedals you can get. 90005 90002 Read our review of the Garmin Vector 3 pedals 90143 Find a Garmin dealer 90005 90024 Favero Assioma Duo pedals — £ 699 90025 90002 This is Italian electronics manufacturer Favero’s second go at power-measuring pedals after the BePro pedals. The spec is like a wishlist of power pedal features: no external pods, so swapping between bikes is easy; Bluetooth and ANT + communications protocols; left and right power; torque efficiency and pedal smoothness; Look Keo cleat compatibility; rechargeable; apps for iOS and Android; and a claimed weight of 299g / pair.90005 90002 And because Favero uses XPedo pedal bodies, you can hack the bodies of XPedo mountain bike pedals to Favero’s power-measuring axles and make yourself a pair of double-sided, SPD-style power meter pedals. 90005 90002 There’s also a single-sided version, the Assioma Uno, for £ 409. 90005 90002 Read our review of the Favero Assioma Duo pedals 90005 90024 VeloComp PowerPod — from ~ £ 200 90025 90002 The VeloComp PowerPod works out your power by measuring the forces working against you, notably air resistance.It sounds like one of those ideas that’s great in theory but can not possibly work in practice, but it’s had favourable reports from riders who tried it and compared its data with other power meters. It also has the advantages of being very keenly priced, and easy to switch between bikes, as it sits on a GoPro-style mount under your bars. 90005 90002 Find out more about the VeloComp PowerPod 90005 90024 FSA PowerBox — £ 439 90025 90002 FSA’s Powerbox power meter crank borrows power2max technology and has an RRP of £ 599 for the aluminium version (including chainrings), though it can already be found for considerably less.That makes it one of the cheapest crank power meters we’re aware of, and the cheapest meter that measures power from both sides. It communicates using the ANT + protocol and battery life is a claimed 300-400 hours from a CR2450 button cell. A recent free firmware upgrade allows you to see the left and right hand readings separately, and enables Bluetooth communication. 90005 90002 If the PowerBox Aluminium’s not-unreasonable 750g weight is too much for your best bike, there’s a 585g version with carbon fibre arms from £ 739.90005 90002 Read our first look at the FSA Powerbox 90005 90024 Avio Powersense — from £ 149 90025 90002 Now shipping, the Avio Powersense service turns your cranks into a left-hand-only power meter that communicates via ANT +. You send in your crank, and Avio sends it back with the power-measuring unit attached, or you can buy a complete chainset with the device fitted. We’re hoping to get a set in for test soon, but it has to be said you can not argue with the price. 90005 90002 Avio now offers a £ 225 DIY kit that includes all the gubbins necessary to turn a Shimano left hand crank into a power meter.Alternatively, you can buy the device fitted to a 105 or Ultegra left hand crank, or as part of a complete crankset. 90005 90002 Read more about the Avio Powersense 90005 90024 Easton / RaceFace Cinch Power Meter — £ 695 + cranks 90025 90002 RaceFace and Easton’s Cinch and is an axle-based power meter that works with the Easton EC90 SL road crankset or RaceFace’s mountain bike Next R crankset. Because the sensors are in the bottom bracket axle, it only measures left hand power, and then doubles it.It communicates with both ANT + and Bluetooth protocols and has a claimed battery life of 400 hours between charges. 90005 90002 Read more about the Easton / RaceFace Cinch Power Meter 90005 90024 Arofly — from ~ £ 230 90025 90002 Arofly is a power, cadence and speed meter that attaches to the valve of your rear wheel and weighs only 10g, including its button battery. It sends your cycling data via a Bluetooth connection to be displayed in real time on a custom mobile app on your smartphone.90005 90002 Dead cheap, dead simple, so what’s the catch? It does not work very well. We found that it simply does not provide measurements that are consistent enough that it can be considered a useful training tool. 90005 90002 Read our review of the Arofly power meter 90005 90024 4iiii Precision Power Meter — £ 219.60- £ 387.20 90025 90002 The 4iiii Precision is a crank-based power meter that delivers sound, usable data, as long as you’re happy with the limitations of a single-sided system.90005 90002 The Precision system consists of a tiny pod that’s bonded to a non-driveside crank arm. In that way it’s similar to a Stages unit. I used the Shimano Dura-Ace version (they’re all Shimano) and it weighed just 9g more than the crank I took off, and that includes the battery. A Shimano 105 version is £ 349, and a Shimano Ultegra version is £ 429, or you can get a complete Praxis Works Zayante DM CarbonX crankset with the 4iiii meter attached for £ 700. 90005 90002 Read our review of the Praxis Zayante CarbonX 4iiii Power Crank 90005 90002 Read our review of the 4iiii Precision 90143 Find a 4iiii dealer 90005 90024 Shimano Dura-Ace FC-R9100-P cranks — £ 1,199.99 90025 90002 Shimano’s power meter is crank based with strain gauges in both crank arms, so it can measure left and right legs separately. It has a discreet ‘brain’ that sits within the spider. See it up there (above) between the top two arms? I told you it was discreet! 90005 90002 It can be paired to third party displays, such as Garmin Edge bike computers. The system checking and firmware upload can be operated by your smart phone or tablet PC through a Bluetooth connection. 90005 90002 Read our review of the Shimano Dura-Ace FC-R9100-P cranks 90143 Find a Shimano dealer 90005 90024 SRM cranks — from £ 1,299 90025 90002 SRM — it stands for Schoberer Rad Meßtechnik, TLA fans — makes a wide range of power meter cranks, taking the original manufacturer’s right hand crank and installing its measurement unit in place of the crank spider.It’s a robust design with an excellent reputation for accuracy and reliability, backed by a three-year guarantee. 90005 90002 Read our review of the SRM Origin Power Meter cranks 90005 90002 Find an SRM dealer 90005 90024 PowerTap G3 hub — from £ 375 90025 90002 You can buy a PowerTap hub on its own or built into a pair of wheels from £ 624.

The meter is housed on a left (non-driveside) crank. You buy the crank with the power meter already installed and swap it for your existing left-hand crank.Stages offer various different models for Shimano, FSA, Campagnolo and Cannondale cranks.
