Which electricity meter would you choose or recommend?

Take the survey

How to choose?

An electric meter is a device that is used to keep track of consumed electricity. When choosing it, you should pay attention to the following points:

The principle of economy;
By power consumption;
Mechanical or electronic;
Difficult to install and use;
Operating time between verifications;
The amount of electricity used for the operation of the meter itself;
Price.

Guided by the desire to save money, it is worth purchasing two-tariff meters. Unlike the most common single-tariff meters, in them the working time is divided into 2 parts: night and day. This makes it possible in large cities to reduce the load on electrical networks by reducing the cost of a kilowatt at night. It is recommended to use two-tariff meters if the residential premises have:

Warm floor;
Washing machine;
Electric heaters.

In the absence of the above factors, you can use a single-tariff meter. It is cheaper in cost and is considered more reliable by experts.

Of no small importance when choosing a meter is the amount of power consumed per day in a given house. The average statistical indicator of power consumption per day is considered to be 10 kW at a current load of up to 60 amperes. All meters are designed for an operating network frequency of 50 Hz. Provided that the load will be more than 10 kW, you must purchase a meter with a current of 100 A.

In order to determine the power used in a residential area, you need to look at the passports of electrical appliances located throughout the house. They indicate the power of each electric assistant. When calculating, their average operating time over 24 hours should be taken into account. Adding up all the data, you get the average daily power, which is taken into account when purchasing a meter.

Which electric meter is better to buy?

Before purchasing, many users wonder which is the best electricity meter to buy. There is no clear answer to this question; first you need to determine under what conditions it will be used.

Conventionally, all electricity metering devices can be divided into two groups:

Household - it is better to install such devices in an apartment or private house, in a garden house or in a garage. As a rule, in such conditions, users consume a small amount of electricity and operate low-power equipment. Simple and inexpensive models that do not pose any problems during installation and use are suitable for accounting.
For industrial conditions, other devices are needed. As a rule, these are three-phase multi-tariff meters of high accuracy. They are designed for integration into complex energy systems. However, in small businesses and in ordinary commercial premises, simpler versions with similar characteristics to household ones are often suitable.

The best choice would be a metering device designed for a certain number of tariffs. If the house actually has triple tariffs, but the meter is only designed for two, it needs to be reflashed for a fee.

It is also worth keeping in mind that the device should be easy to use. Regular difficulties during operation for a long time will cause a lot of inconvenience. There are no similar ones in the rating of electricity meters from our editors; the experts excluded all, even popular, models that could complicate everyday life. A review of top-selling devices in terms of quality and sales will help you easily choose the best electricity meter based on price, reliability and consumer properties.

Types of meters

Electricity metering devices of our time are presented in two types: mechanical and electronic. Experts say that the first type of electricity meters is the most reliable and durable. The advantages of the latter are the ability to save various information about the electrical network: peak power consumption, voltage drops and other indicators depending on the model of the device.

The choice of electric meter will also be affected by:

Electric company terms and conditions. They may stipulate the possibility of installing a specific type of meter.
Temperature conditions at which the device will be used. Most meters are designed for installation in rooms with temperatures above 0 degrees, but there are a number of models that can operate at 45 degrees. This allows you to install them outdoors and in unheated rooms.
The passport for the meter must contain a GOST certificate of conformity, as well as a permit allowing it to be installed in Russia.
You should check with the seller about the presence of seals on the device, which confirm that it has passed the state inspection. For single-phase meters, it is stipulated that the seal should not be older than 2 years, and for three-phase meters - no more than 1 year. Otherwise, a repeated state verification of accuracy is provided, and only after this is the sale of the goods allowed. According to GOST, accuracy class is 2.
The meter's passport must contain a state inspection seal. And it itself should have clear contours, made of red or black mastic, less often it can be covered with silver.

What circumstances may force you to choose a new electric meter?

Electric meters are devices with a very long service life. They can serve faithfully for decades. However, sooner or later there comes a time when this energy meter requires replacement.

Let's make a reservation right away. Unfortunately, the existing legislation does not give a completely clear idea of who should be responsible for the financial side of replacing the electric meter in an apartment in a multi-storey building. There are many interpretations, with various manifestations of legal casuistry. There are many cases proposed for consideration where the obligation to purchase was assigned either to the residents, or to the management company, or to the electricity supplier. Sometimes these issues are regulated by local legislation or are specifically stipulated in contracts or other documents. In any case, before purchasing a meter yourself, it would be wise to clarify this issue directly on the spot.

Before purchasing an electric meter yourself, it would be wise to clarify who is assigned this responsibility in specific conditions, under existing contracts?

This is not what our publication is about. We will discuss below those cases when the purchase of a metering device is required by apartment owners.

So, in what cases may it be necessary to replace an electric meter?

No matter how reliable and accurate the meter may seem, and no matter how satisfied the owners are with it, it will have to be replaced with a new one if its service life established by the manufacturer has expired. These periods are considerable - they reach thirty years or more, but they still end sooner or later. Usually the date of manufacture is indicated both in the passport and on the body of the electric meter.

The meter may seem to be in perfect working order, but if its service life has exceeded the permissible norm, the device must be replaced

The meter has failed - naturally, immediate replacement is required. True, if the warranty period for the device has not expired, it must be replaced with a working one, or the costs of purchasing a new one must be reimbursed.
For one reason or another, the meter showed mechanical damage to the housing or glass, signs of burglary or other vandalism. Litigation for reasons most likely cannot be avoided, but a replacement will definitely have to be made.
The inspection interval established by the manufacturer or local energy supplier has been exceeded by more than two years. Even if the meter gives no reason to doubt the accuracy of the readings, it will most likely be forced to be replaced.

You should never forget about the timing of mandatory checks of metering devices. Failure to comply with them may also result in mandatory replacement of the meter.

The technical characteristics of the device no longer meet either modern requirements or actual conditions of use. For example, devices with accuracy class 2.5 and worse are completely taken out of service. According to current legislation, replacement is mandatory during scheduled inspections - it is allowed to use the old ones before the expiration of the inspection interval. Another option for discrepancy in characteristics is that the old meter’s permissible current indicators no longer suit the owners due to the increased load.
The owners want to switch to a system of differentiated energy consumption metering and, accordingly, install a meter with such functions.
A planned general replacement of all metering devices in this apartment building is also possible. However, in this case, all costs will most likely be borne by either the management company or the energy supplier. And most likely, owners will not be given the opportunity to independently select a meter.

The best manufacturers

When buying an electric meter, when choosing, it is advisable to pay attention to devices produced by companies that have proven themselves on the positive side. These include:

Incotex. A company operating in Russia. Her experience in the market is 15 years. Part of the strongest diversified holding. It produces electricity meters under the Mercury brand. They are in the leading position in the Russian market in terms of sales.
Energy meter. The largest manufacturer of meters on the Russian market.
Typeit. This company appeared in 1999 in the northern capital of Russia. They produce meters and other products for measurements under the Neva brand.

Buyers are also interested in the price of the device. The functionality provided depends on how much it will cost: the number of tariffs, accuracy and its class, design model and technical characteristics.

Why do you need to know the degree of protection?

For safety, electric meters must be protected from external influences. Pay attention to their degree of protection. It is designated by the letters IP and two numbers, for example IP 56.

Both numbers are a code symbol. The first shows the degree of protection against the penetration of foreign objects, the second - from the ingress of water.

Let's talk about this in detail. The first number means the maximum size of an object that can get into the device: 0 - there is no protection at all, and any object can interfere with the operation of the device, 1 - objects less than 50 mm, 2 - less than 12.5 mm, 3 - less than 2.5 mm, 4 - less than 1 mm.

If the first digit after IP is 1, it means you can easily touch the internal mechanisms of the device with your finger, 2 - with a tool, such as a screwdriver, 3 - only with a wire. It is almost impossible to pass the remaining levels of protection.

The second digit of the code value indicates the degree of protection from water: 0 - no protection, 1 - water flow from above will not enter the mechanism, 2 - minor drops will not interfere with its operation, 3 - the device will withstand rain, 4 - there is protection from direct water ingress , but not under high pressure, 5 - will tolerate a low-pressure jet, 6 - can withstand the ingress of water with a strong jet pressure, 7 - will remain operational after a short immersion, 8 - will work even after a long immersion.

Most often, devices with a degree of protection of IP 55 and higher are purchased - rain will not interfere with the operation of the device, and dirt and dust will not get into it.

The design includes a measuring shunt, which ensures high accuracy and resistance of the device to electromagnetic interference. Meters of the CE 101 are available in different housing options: for mounting on a DIN rail, and on a plane for bolts.

Which electricity meter should you choose?

There are several criteria by which devices can be divided among themselves. Due to the design features, they are divided into induction and electronic. For a long time, apartments and houses were equipped only with induction meters. A distinctive feature of such devices is a rotating disk. Such devices do not have a high accuracy class.

In the 21st century, electronic meters appeared. They are equipped with a liquid crystal screen. But the main advantage is their accuracy in readings. This helps them lead the market.

Meters are also produced in single-phase and three-phase. The first ones are most often installed in apartments. And in houses with boilers, boilers and electric motors, it is recommended to use three-phase ones. Recently, multiphase devices have begun to be produced. They help distribute energy wisely, which does not create congestion in the network. Users note significant savings when metering energy with such meters.

Is unbalanced meter load a problem?

We often wonder how the asymmetric load on the wires affects the accuracy of the readings, and also which three-phase meter to choose for a private home. Let's imagine a situation in which electric heating is connected to one phase, an induction cooker is connected to another, and the third phase is responsible for the remaining small household appliances. In summer we do not heat the room, so one phase is completely unloaded. Does this affect the measurements taken? A very similar problem is the operation of a device with only one or two phases connected.

Fortunately, electronic electricity meters are excellent at dealing with such problems. We don't need to have a symmetrical load or even all phases connected to the device. This is due to the meter design. Each phase is measured completely separately, and the zero measurement is simply added to the non-zero value and displayed on the LCD screen.

Helpful Tips:

For buildings such as a garage, which use welding machines, compressors and other energy-intensive equipment, it is necessary to purchase more powerful meters.
Before purchasing, it is advisable to read thematic forums and reviews.
It is worth finding out how much repairs will cost if necessary.
You should ask the seller about how noisy the device is, otherwise its buzzing will be very annoying.
When purchasing a mechanical type of device, you need to check it. You should turn the disk by hand. If it is working properly, it will rotate by inertia.

Electricity metering devices are designed to last for decades, and also require sealing and issuance of documents. These factors influence the need to purchase a high-quality electric meter to avoid problems.

Installation

The electric meter must be installed by qualified specialists. Working with electricity is complex and unsafe, and it is important to do everything correctly. An electrician from the energy supply company has the right to unseal and seal the meter.

Mercury 230

There is no prohibition to involve an electrician from a private company in the process, but the employee must have permits for such activities. The specialist installing the device must have a good understanding of the issue. Installing a single-phase multi-tariff meter will cost the user more than installing a single-tariff device.

There are certain rules regarding whether the homeowner must maintain and replace the meter.

Provided that the flow meter is installed in a public place, it is public property. In this case, expiration dates and timely replacement are controlled by authorized services.
Provided that the meter is located in an apartment, house, etc., the owner is responsible for the condition and timely replacement.

The contract may contain other conditions; it is necessary to study the document. A standard agreement, an act on the division of balance sheet assets are the main documents that should be in the hands of the owner.

To replace the meter and install a new flow meter, you need to prepare the following documentation:

submit an application to the energy company;
draw up an act;
carry out the procedure for verifying the old metering device;
seal the installed electric meter.

Cascade Mercury AT-01

In addition to the documents mentioned, you need to prepare a standard package of papers:

a document confirming ownership where the flow meter is required to be installed;
power of attorney, if the application is submitted by the owner’s assistant;
photocopy of passport.

To install the flow meter correctly, you must follow the basic installation rules:

The device must be located in a place of free and unobstructed access. Maintenance or verification should be carried out without difficulty.
The line must be de-energized for the entire period of installation of the device. This is pre-agreed with company representatives.
The height of the meter from the floor level is from eighty to one hundred and seventy centimeters.
The device must be grounded.
All machines must be connected to a meter.
If the integrity of the seal is damaged, it is important to immediately call a specialist to reseal it.
After installing the flow meter, a test run is performed.

Installing a meter on the street raises many questions. There are no documents regulating the location of the device.

The user independently decides where to place the equipment.

Representatives of the energy sales company insist on street placement of the meter, but the user should be aware of the following facts:

Installing the device outside significantly reduces the service life of the flow meter. Unfavorable environmental conditions negatively affect the condition of the device; at minimum ambient temperatures, readings are often incorrect.
Placing the device outdoors implies the possibility of uncontrolled access to the device by third parties.
To prevent theft or damage to the meter, they are often installed at a height of three meters. The user has to take readings using a ladder.

There are a number of requirements for installing an electric meter:

The flow meter is installed in electrical cabinets, on rigid panels.
The recommended installation height of the device is from eighty to one hundred and seventy centimeters.
When the meter is located in places with an increased likelihood of damage, clogging or access by third parties, the meter is installed in a lockable structure.
For ease of maintenance and readings, the flow meter should be located in a place convenient for access.
It is important to choose the correct diameter of the input cable.
The input cable cannot consist of elements fastened together.

In private households, it is possible to lay electrical wiring from the meter in the ground, at a height in the air.

Which meter is the best for a house or apartment? Despite the great popularity of electronic metering devices, mechanical electricity meters remain in demand. The absence of the need for expensive maintenance, high reliability and long service life speak in their favor. In European countries, interest in familiar, unpretentious electromechanical flow meters is increasingly being revived.

Which device to choose needs to be decided based on a lot of factors. Choosing the best metering equipment requires careful consideration.

By mounting method

Devices can be attached:

on DIN rail;
using screws.

Meter manufacturers provide the possibility of mounting the meter on three screws (for conventional electrical panels) or on a DIN rail. The device is installed on the rail in line with the machines. This makes it possible to save space.

Important! The installation of the metering device must be carried out by a specialist who has permission to perform work under voltage up to 1000 V.

Assembling the meter in an installation cabinet

For installation, choose a place in the hallway or hallway of the house. Most often, the cable supply from the power pole is carried out through an intermediate support in the courtyard of the house. Your task is to install the cabinet, bring the corrugated cable to the support, connecting the cable to the line is assigned to the specialists of the energy network company. In addition to the overhead connection scheme, it is allowed to supply the cable to the house through a plastic or underground asbestos pipe. But in this case, the company will require that the cabinet with the electric meter be placed on a pole outside the household.

If you have agreed to the remote option of installing a cabinet with an electric meter, no one cares how you will continue to run the cable into the house. You can install supports or bury it to a depth of 0.7-0.9 m, as required by the rules. You just need to make a panel with packages to disconnect individual wiring segments and equip the grounding.

The cabinet is a box made of thin sheet metal with a door. Inside the box there are fasteners that facilitate the installation and installation of the main devices - the input package, the electric meter and the packages on the wiring distribution.

The input package, like an electric meter, is always equipped with an additional cover covering the contacts. The lid must have an industrial “ear” or cell for sealing.

The contacts from the input cable are connected to the package according to the diagram shown.

Next, you need to connect the phase and zero wires to the meter input; for this, use copper pieces of wire in colored polyvinyl chloride insulation. For installation, according to the rules, it is necessary to use copper wire with a cross-section of 1 mm2 per 10 amperes of current, but in practice, installation is carried out with a small margin - in sections with a cross-section of 5 mm2. Choose a dark wire for the phase wiring, a light one for the zero line, and follow this rule for all electrical wiring and installation of current consumers in the house.

The meter pin diagram for connecting the wiring is always provided on the body or cover of the device as an aid to installation. If you open the terminal box, it will become clear that the input and output of the phase wire are on the left, the inlet and outlet of the neutral wire are on the right.
