Top 10 best single-phase meters - choice of single-tariff and multi-tariff meters

An electricity meter is needed to account for resource consumption and control it. You always want to choose a reliable and durable device. High-quality equipment is distinguished by high reliability and maximum accounting accuracy. A single-phase meter can be installed in an apartment or in a residential building.

For ease of choice, we have collected on this page the best and most current electricity meters. The list is compiled taking into account the characteristics. You need to look not only at the cost, but also at the price-quality ratio.

Which meter is better can only be said by knowing the specifics of using the device at a specific facility. Before buying a meter, decide on the following parameters:

Network - single-phase devices are suitable for use in a 220 V network; for a 380 V power network, three-phase models are used.
Tariffs – the price of a kilowatt of energy largely depends on the time of day. During peak loads it is maximum, at night it is noticeably cheaper. If you can save on this difference, pay attention to multi-tariff metering devices.
Measurement accuracy - minor errors are acceptable, but not more than 3%.
Brand – by choosing equipment from trusted brands, you get guaranteed quality. Meters "Mercury" and other domestic brands are in demand today due to their accuracy and affordable price. They have a simple design, are unpretentious in operation, and durable.

The more a device can do, the more expensive it is. Thus, meters that transmit readings without user intervention (appropriate settings are required) are more expensive than simpler analogues with manual data processing.

What to look for when choosing

Before purchasing, you need to find out what specific meter your apartment or house needs. This information is in the specifications for the electrical supply of the apartment, where all parameters are indicated. If there is no document, it is worth determining the voltage (220 or 380 V). For 220 V you will need a single-phase meter, and for 380 V - a three-phase one.

Accuracy class

The indicator indicates the maximum possible percentage error from the largest value during accounting. According to the rules, devices with an accuracy class of at least 2 for an individual are accepted for operation, and for a legal entity - no more than 1. Today meters are produced with KT 0.2, 0.5, 1, 2. According to GOST, the number is indicated on the unit display in a circle.

Maximum/rated current

The maximum current is determined based on the total power of all electrical appliances. The information is in the power supply project; if it is missing, you can look at the panel of the old device.

Single-tariff/multi-tariff

Determines how many tariffs are included in the device. Multi-tariff is suitable for private homes - at night you can switch to increased heating and achieve significant savings.

Fastening method

Two types of fastening are used - bolted or dinrail. The latter is considered universal and is recommended by many experts.

Single-phase/three-phase

Selected depending on the type of power supply in the apartment. If a cable with 2 cores is supplied to the input circuit breaker, then a single-phase meter is suitable. If a cable with 4 cores is used, then a three-phase one is required.

Company manufacturer

Brands such as Energomera, Incotex, Taypit, and ABB have proven themselves on the market. They independently develop and produce products that meet all safety requirements.

INCOTEX Mercury 201.5 (from 625 rubles)

INCOTEX Mercury 201.5.
Photo: market.yandex.ru One of the most popular models on the Russian market of electric meters. This will be in almost every hardware store, market or small department. The price is ideal for an apartment device. The device itself is made of plastic, and not particularly durable. Therefore, the manufacturer advises: it is intended for indoor use and where there is protection from environmental influences. That is, in cabinets and panels. Energy is measured digitally. The composition does not contain magnetically sensitive elements. This means that intentional or accidental exposure of devices to a magnetic field will not damage or break the meter. The device is compact, mounted on a DIN rail - it is a cheap steel die, which, depending on the size, costs 15-50 rubles in a construction site.

Characteristics : electromechanical, accuracy class 1.0, DIN rail mounting, rated current 5 A, maximum current 60 A, minimum frequency 50 Hz, maximum frequency 51 Hz, included in the state register, two-wire connection, direct

Energy meter CE 101 R5.1 145 M6.
Photo: market.yandex.ru Another fairly common domestic device. Due to its low price, it is popular with developers. But it’s also common in stores. The body is small in size. There are no installation features: the main thing is a flat wall and a DIN rail. The device is certified and entered into the state register. Therefore, if you have a simple single-phase tariff, you can safely purchase it. Note that the company has two models under this name. The first one has a mechanical screen: the usual cells with numbers. The second one has a liquid crystal display - like an electronic watch. It's more expensive. The difference is only external. Although the manufacturer himself says that the digital screen supposedly protects against electromagnetic fields. But this is rather a cunning trick. Even with a conventional display, the device is protected by all standards. We also note a good warranty on the devices - seven years.

Able to calculate energy consumption at different times of the day. The main thing is not to forget to connect the tariff so that this function pays off. The device itself is neat and not bulky. The readings are clearly visible on the LCD display. Please note that to operate it during power outages, you need a CR2450 battery - “puck”. But it can be easily replaced without opening the case. For this purpose, the manufacturer installed a capacitor. The device's memory stores daily values and readings for 128 days. There is an electronic seal. This is a sensor that records unauthorized opening in the device memory. However, according to the law, you still have to put a regular seal on the device. The display can display energy consumption at the end of the month according to tariffs. Similar figures for the previous 16 months are stored in memory.

INCOTEX Mercury 200.02.
Photo: market.yandex.ru Compared to competitors with the possibility of two-tariff measurement of indicators, this one has an acceptable price. Therefore, we confidently place it among the best electricity meters. In case you didn't know, you can ask the electric grid company to switch you to a separate charging tariff. Then at night a kilowatt will cost a penny, but during the day the price is higher. Convenient if you are a night owl or your job is such that the main energy consumption occurs at night. Some people, for example, do laundry, cook, etc. with this tariff only in the evening. In addition, this counter can immediately transmit data to ASKUE. Behind the abbreviation lies an automated system for collecting readings. True, in Russia this is only available in advanced new buildings, where they decided to take care of energy efficiency. For others, the bells and whistles will be useless. Note that some data can be displayed on the local display. For example, information on expenses for the past month.

It is also made of non-flammable materials. Therefore, if someone suddenly cares about the appearance of metering devices, then you can take a closer look at this model. Suitable not only for home, but also for installation in public spaces and industrial enterprises. The company boasts that the column with terminals is made of polybutylene terephthalate. This is such a polymer. What does this mean to the average consumer? Actually, not much, except for greater confidence in the reliability of the device’s contacts. Note that the case has a rubber seal installed, which provides protection according to the IP51 standard. This means good protection from dust, and a little protection from water - literally from drops.

It's even assembled in such a way that it can't be taken apart. This is good from a device security point of view. This device is mostly suitable for home use: in an apartment, cottage or garage. But the specifications indicate that it can also be used to account for consumption in public buildings. In addition to the mechanical display, there is an LED that serves as an indicator of proper operation and flickers in proportion to the amount of energy consumed. Just in case, let’s clarify that it blinks quite often. Therefore, if the device is located somewhere in an open area, and you are annoyed by various flashes, even small ones, then you will have to tape it up or hide the counter in a closet.

EKF SKAT 301M/1 R PROxima.
Photo: market.yandex.ru The most advanced and reliable electricity meter on the Russian market. But you have to pay for quality. It is protected from increased input voltages and impulse noise. Although, if everything is fine with the wiring in the house, then the loads that the device is capable of receiving are unlikely to be needed in everyday life. The declared service life is at least 30 years. In general, other manufacturers also quote a similar figure. Only this is again a trick. As we have already said, the calibration interval of the device is indicated in the passport. The verification procedure is not cheap, so it is cheaper to simply buy a new device. But the factory warranty is only five years. Competitors give more. Although the model is innovative, the dimensions and locations of the seats coincide with the location of the mounts on the old meters. This means there should be no problems with installation. To help, a DIN rail or mounting platform costs about 150 rubles.

Energy meter CE 101 S6 145 M6.
Photo: market.yandex.ru In our rating of the best electricity meters, we have already mentioned the device of this Russian manufacturer. Frankly speaking, there is not much difference between them. Except for the fact that as of 2022 this device is newer. The case is made of more durable plastic, there is contact protection so that the connected wires do not stick out. This is a one-tariff device without any tricks. The reading device is mechanical, behind frosted plastic glass. It does not consume much electricity; there is a light that lights up if everything is normal with the device. Thanks to its housing, the device is better protected from the external environment than a cheaper analogue from the same line. The class of protection against dust and moisture is not specified. But with careful everyday use, it’s clear that everything will be fine with it, even if you don’t hide it in a cabinet.

INCOTEX Mercury 201.7 (from 560 rubles)

INCOTEX Mercury 201.7.
Photo: market.yandex.ru Another inexpensive device for 2022 from the “set it and forget it” series. The body is made of budget plastic. Reminds me of the materials from cheap Chinese toys that littered the kiosks 15-20 years ago. However, this does not affect the accounting characteristics in any way. The device regularly keeps a chronology of electricity consumption. You just need to handle it during installation with the utmost care, so as not to inadvertently split the housing with the tool during installation. It is best if this is placed behind a protective cabinet. Then nothing will happen for sure. The device is certified and included in the state register for use in homes. The device is indifferent to the magnetic field. There is an anti-reversal mechanism that prevents the digits from rotating in the opposite direction. Taking it apart and seeing what's inside won't work: the case is made in such a way that any attempt to open it will destroy it and it won't be possible to restore its integrity. This means you won’t be able to put a filling.

You can screw it on with three screws, as you did before. Or put it on a DIN rail model TN35. Most of the markings are applied not with paint, but with laser engraving. This is a plus for the durability of the device. The connection is simple: the installers will thank you. Let us remind you that by law you can install the device yourself. Or hire a specialist. But only network specialists can connect and seal it. The terminal block screws do not fall out - they remain in their sockets when fully unscrewed. The manufacturer claims that the connection securely fixes the wires. There is a familiar flickering indicator that emits light pulses based on the amount of energy consumed.

Principle of operation

Due to the constant improvement of technology, electricity meters are also being improved. All single-phase models presented on the modern market are divided into induction and electronic.

Rice. 1. Induction and electronic electricity meter

The first option is a pioneer in the electrical energy metering system; despite their simplicity and availability, electronic electricity meters are gradually replacing them due to their high accuracy and expanded functionality.

Induction electricity meters

Induction electricity meters have a simple and understandable design, using an example of which it is relatively easy to understand the structure and operating principle of a simple electricity meter.

Rice. 2. Device of an induction electricity meter

Structurally, this model consists of:

Current winding - is an inductance coil connected to the circuit in series with the load. Designed to measure the amount of current consumed by the load, it is made of large-section wire of several turns.
Voltage windings - also represented by an inductor, but connected in parallel to the current winding. Made from thin wire and laid in a large number of turns, it is used to measure voltage.
An aluminum disk is an element of an electricity meter designed to convert electromagnetic force into mechanical work. Installed on an axis for rotation in the direction of the forces of the electromagnetic field of the inductor coils.
Counting mechanism - converts the number of revolutions of the aluminum disk into a digital display of power measurement results. Consists of a gear-type mechanical dial.
Permanent magnet - used to smooth out mechanical vibrations of a moving disk. Creates a constant magnetic flux and ensures smooth running.

The principle of operation of an induction electricity meter is that when connected to an electrical circuit, the current rated voltage is supplied to the voltage winding. If a load is connected to the terminals of the electric meter, a certain amount of current will flow through the current coil. When two electromagnetic fields interact, eddy currents will begin to be induced in the aluminum disk, which will create its own electromagnetic field. The mechanical force from the disk is transmitted through the gear system to the counting mechanism.

The magnitude of the EMF induced by the current and voltage winding interacts with the own field of the moving element, which is generated due to eddy currents. The measure of this interaction determines the rotation speed of the aluminum disk. The greater the current flowing through the current coil, the greater the result of the geometric product of voltage and current.

Rice. 3. Geometric power calculation by electricity meter

The resulting power value will spin the disk faster, which will lead to faster accrual of the electricity meter readings.

Electronic electricity meters

With the development and improvement of technical means, the modernization of classic induction electricity meters has occurred. Initially, hybrid electronic-mechanical models were produced, but over time, electronics increasingly replaced moving parts. Structurally, a modern electronic model of an electricity meter consists of:

Rice. 4. Electronic electricity meter device

Current sensor – measures the amount of electric current flowing through the electricity meter;
Voltage sensor - designed to measure the potential difference applied to the meter terminals;
Electronic converter – calculates the power passed through the electricity meter;
Microcontroller – transmits readings to the display and to the memory unit, can retrieve data, process it and transmit it via communication channels;
Display – designed to display survey data from the electricity meter, can switch information in multi-tariff models;
RAM and ROM blocks are RAM and long-term memory designed for storing and processing information.

The operating principle of an electronic electricity meter is based on measuring the current and voltage applied to the connected load. The readings are recorded by sensors and transmitted to an electronic converter, which calculates the amount of power and converts the unit of measured value into a counting pulse. The signal from the converter is transmitted to the microcontroller, which, depending on the set response program, displays the necessary parameters of the electrical circuit. In addition to broadcasting current readings to the display, the microcontroller writes information to a memory block and retrieves it if necessary.

There are no side holographic counters.

Advantages:
1 accuracy class;
increased maximum current;
compact dimensions;
quick easy installation;
resistance to environmental conditions.
Flaws:

Classification of tariff rates

The Committee on Prices and Tariffs of the Moscow Region has established tariffs for the following houses and apartments:

Tariffs for apartments and houses with gas stoves.
Tariffs for apartments and houses with electric stoves.
Tariffs for apartments and houses in rural areas.

For each tariff, summary tables with prices and calculations of the profitability of using a particular tariff will be given below. We analyzed our own electricity bills and came up with average electricity consumption in the summer - autumn period: 10% in the night zone, 40% in the peak zone and 50% in the semi-peak zone. These figures are averages and may differ from yours. Therefore, for the maximum calculation, it is worth substituting your electricity consumption indicators during the day and night into the calculation.

Is a multi-tariff meter beneficial for apartments and houses with gas stoves?

The indicators given below in the table are equivalent to the ratio rub/kWh

Single tariff		5,56
Two-tariff	Night zone T2 (23.00 — 7.00)	2,41
Two-tariff	Day zone T1 (7.00 — 23.00)	6,39
Multi-tariff	Night zone T2 (23.00 — 7.00)	2,41
	Half-peak zone T3 (10.00 — 17.00, 21.00 — 23.00)	5,56
	Peak zone T1 (7.00 — 10.00, 17.00 — 21.00)	7,23

The average monthly electricity consumption for apartments with gas stoves is 200 kW - this figure is also averaged and may vary depending on the number of consumers in the house and the time people spend in it. You can see your electricity consumption in your latest electricity receipt.

So, the cost of 200 kW of electricity that we burn per month for the above tariffs will be:

Single tariff: 200 * 5.56 = 1112 rubles.
Two tariff:

T1: 200*0.9*6.39 = 1150.2

T2: 200*0.1*2.41 = 48.2

Total for T1 and T2 = 1198.4 rubles.

Multi-tariff:

T1: 200*0.4*7.23 = 578.4

T2: 200*0.1*2.41 = 48.2

T3: 200*0.5*5.56 = 556.0

Total for T1, T2 and T3 = 1182.6 rubles.

So, calculations show that with summer electricity consumption based on consumption metering of 40/10/50 (T1/T2/T3), multi-tariff metering loses to single-tariff metering and wins quite a bit over two-tariff metering. In order for multi-tariff metering to become more profitable than single-tariff metering, the consumer should increase electricity consumption T2 at night and reduce T3 during the day by at least 10%, which will lead to an amount of 1111.6 rubles for multi-tariff metering (for 200 kW per month).

If you are ready to do laundry, bake bread or iron things more often after 23.00, then a multi-tariff meter will help you save. Otherwise, the single tariff will have priority. We also note that installing a multi-tariff meter can cost a person an additional 1,500 to 4,500 rubles, depending on the number of phases. For example, a single-phase meter INCOTEX Mercury 200.2 will cost the buyer 1,545 rubles.

Is a multi-tariff meter beneficial for apartments and houses with electric stoves, and for the rural population?

Most new buildings in Moscow are equipped with electric stoves, so electricity consumption in such apartments is much higher than in gasified houses. Because of this, tariff prices are slightly lower. The table below shows tariff rates for apartments equipped with electric stoves and for houses in rural areas.

Single tariff		3,89
Two-tariff	Night zone T2 (23.00 — 7.00)	1,68
Two-tariff	Day zone T1 (7.00 — 23.00)	4,47
Multi-tariff	Night zone T2 (23.00 — 7.00)	1,68
	Half-peak zone T3 (10.00 — 17.00, 21.00 — 23.00)	3,89
	Peak zone T1 (7.00 — 10.00, 17.00 — 21.00)	5,06

We took average monthly electricity consumption of about 500 kW - regular use of an electric stove, washing machine, boiler, microwave and electronics. We take the same ratio of electricity consumption for multi-tariff and two-tariff as above: 40/10/50 and 90/10, respectively. The cost of 500 kW will be as follows:

Single tariff: 500 * 3.89 = 1945 rubles .
Two tariff:

T1: 500*0.9*4.47 = 2011.5

T2: 500*0.1*1.68 = 84;

Total for T1 and T2 = 2095.5 rubles.

Multi-tariff:

T1: 500*0.4*5.06 = 1012

T2: 500*0.1*1.68 = 84

T3: 500*0.5*3.89 = 972.5;

Total for T1, T2 and T3 = 2068.5 rubles.

Here, as in the previous calculation, multi-tariff accounting is more profitable than two-tariff accounting, but more expensive than single-tariff accounting. To increase the “profitability” of the multi-tariff rate, it is necessary to reduce consumption during the day and increase consumption at night by at least 12%, which will lead to an amount of 1935.9 rubles for multi-tariff accounting. Thus, to profitably use a multi-tariff meter, it is necessary to spend electricity in a percentage ratio of at least 40/22/38 for T1/T2/T3.

Of course, it is best to reduce electricity during peak hours. However, this is quite difficult in the modern pace of life. If you consume an average of 500 kW per month and you don’t care about losing 100 rubles, then leave a single-tariff meter. If you have an active “night life” or an electric boiler with which you are going to heat your apartment at night in winter, then a multi-tariff meter will be very beneficial for you.

Conclusions: who benefits from a multi-tariff meter and who does not?

Multi-tariff electricity metering WILL NOT BE BENEFITABLE :

For those who work from 8.00 to 17.00 and cannot avoid peak load.
For those who have relatively few electrical appliances or most of them work during the day.
For those with wood or gas heating.
In places where a person is located exclusively in the summer, for example, in a country house or in a country house.

Multi-tariff electricity metering WILL BE BENEFITABLE :

For those who have electric heating or heated floors that operate mainly at night.
For those who have a lot of powerful energy consumers in the house that can be switched to night operation, for example, a washing machine, bread machine, pumping station, etc.

Typeit NEVA 103 1S0 230V 5(60) A 5(60) A

Single-phase single-tariff device with a mechanical dial. The maximum current is 60 A, voltage is 220 V, accuracy class is first. Installation is quick and convenient - on a Din rail. Additionally, there are latches that do not break during operation.

The dimensions of the Typeit NEVA 103 are modest, which is, of course, a plus; the dial includes 7 fairly large numbers. The readings are not saved, which, of course, is inconvenient in case of network failures. If the readings are incorrect, during sealing the calculations will be performed based on average indicators. The maximum operating time is 280,000 hours on average. The warranty period from the date of creation is 7 years. The average service life promised by the manufacturer is 30 years.

Advantages:
affordable price;
maximum reliability;
ease of installation;
a complete list of guarantees;
convenient fastening of wires.
Flaws:
According to reviews, marriage sometimes happens.

How to choose an electricity meter

We talked about the best electricity meters available for sale in 2022. Let's turn to professionals for advice on choosing. , senior specialist in the electrical goods department of the online hypermarket VseInstrumenty.ru, became our consultant .

Remember the law

From July 1, 2022, responsibility for installing electricity meters has shifted to energy and network companies. Consumers no longer have to pay separately for this service. Standard electricity meters will be gradually replaced by smart ones - they automatically monitor electricity consumption and transmit data directly to the service provider.

What to look for when purchasing

If you still need to purchase and install an electricity meter at your own expense, you need to pay attention to the following parameters:

Construction type . Mechanical is cheaper, but less accurate. Electronic is more expensive, but more accurate and can be multi-tariff, allowing you to save in the future.
Intervalidation interval . For a mechanical one, a good indicator is 16 years, for an electronic one – 8 – 10 years.
Brand . Popular are Incotex (Mercury), EKF, and Taipit (Neva). On average, the price for single-phase single-tariff meters does not exceed 1000 - 1100 rubles. The price for four-phase starts from 2000 - 2500 rubles.

Types of single-phase meters

Electricity metering devices are divided by connection method, type of measured values and type of design. They are directly connected, when the device is directly connected to the power supply. They can work using transformers. However, almost all devices are directly connected to the network. The single-phase meter operates on a 220 V network, so it is installed in almost every home.

According to the type of design, single-phase devices are divided into two groups:

induction - the wasted electricity is measured using an aluminum disk that rotates in a magnetic field; the disk rotation speed depends on the power consumption;
electronic - the power of electrical energy is measured by pulses.
