In many families, the question of saving the budget more often arises. This can be partially solved with the help of saved kilowatts. Get recommendations on which electricity meter is best to put in the apartment, so that it meets modern requirements and helps reduce financial costs.

How to choose an electric meter in an apartment

Before you go to the store selling electric energy meters, you need to decide which electric meter is best to put in the apartment, based on individual family requests. A specialist associated with electrics will help you to select a meter that is optimal for the price and functions according to several criteria. There are several points that you should pay special attention to:

• the savings that the device will bring;
• ease of installation and use;
• reliability;
• the period between inspections;
• silent work;
• low power consumption by the recorder.

Which electric meter is better to put in the apartment

Knowing the rules of how to choose an electricity meter for an apartment, it is easy to determine a more suitable purchase option for each criterion. The advice of a specialist who regularly works with the wiring and installation of metering devices for electric energy consumption is important. Recommendations will help to save money not only when buying at a cost, but also in the future work process..

Types of electricity meters for an apartment by type of construction

Despite the fact that there is a massive replacement for new generation meters, both representatives have their drawbacks and positive qualities. The difference is in the applied principle of operation:

1. Induction – work on the principle of counting the number of disk rotations. Features:
   • Plus – ease of use, low price, long time between checks.
   • Minus – low accuracy, the inability to break down in time to switch to a multi-tariff calculation of energy consumption.
2. Electronic – have microchips that read information about the transformation of the flow of electricity. Features:
   • Plus – accuracy, compact size, multi-tariff metering.
   • Minus – high cost, low reliability.

Choosing an electric meter for an apartment by the number of phases

Based on the number of phases connected to the apartment, the meter is selected for specific parameters. Devices are divided into the following categories:

• Single-phase, which have four terminals for fastening (two to the incoming core and neutral wire, and two to the output).
• Three-phase, having at least eight terminals (one zero and three conductive at the input and output). This type of meter can be used for an apartment where one or three phases are connected.

What accuracy class should an electric meter have?

Any device has an error according to indications. Variations of indicators will depend on the accuracy class of the electric meter – a deviation of how many percent is allowed from the true amount of energy consumed. For domestic use in an apartment, the average parameter of the accuracy class is acceptable – no more than two percent. This means that with a real consumption of 100 kW, the readings will be from 98 to 102 kW. The smaller the number, indicated by the accuracy class, indicated in the technical passport, the smaller the error. Such electricity meters are more expensive in value.

Determining which electric meter is better to put in the apartment, starting from the percentage of error, you can stay in the 2nd class. In total, there are several types of devices that record consumed electricity. Allocate according to the accuracy class of the device, “erring” on:

• 0.2-0.5%;
• 1.0-2.0%;
• 2.5%.

How to put a meter on electricity by the number of tariffs

At the time of purchase, the question may arise which electric meter is better to install in the apartment, based on the number of tariffs that the device can switch to. There are three types of counters:

• single tariff;
• two-rate;
• three-tariff and more (multi-tariff).

The choice depends on the lifestyle of the owners. For those who are used to getting up around 7 a.m. and about 23 p.m. already sleeping, an old-style single-rate electric meter is best. A more economical option is to consider those who, having a two- or multi-tariff meter, will perform some household work in the same periods. For example, the operation of the washing machine, the maximum heating of electric heating and other “costs” after 23 hours, when the payment for 1 kW is lower, will be economical.

When calculating a month or a year, the difference in the cost of paying for the service differs significantly. Installing electricity meters in an apartment, such as Mercury (with an event log), is becoming increasingly popular. Devices keep records of several types of tariffs and automatically adjust the load on the network. Get used to counting and saving your costs. To do this, you only need to program the mode when it is most profitable to turn on one or another household appliance without creating a peak load.

Types of electricity meters by current

Single-phase meters can operate in a range with a current strength of 5 to 80 A. Three-phase meters – from 50 to 100 A. More accurate data are indicated on the meters by the manufacturer. The smaller the current range, the lower the price of the device. The type also depends on the thickness of the cable that is connected to the building. The specialist who will be involved in the installation of the meter in the apartment must have information about the condition of the wiring.

The price of electricity meters for an apartment

Owners when buying an electric meter are not least interested in the price. How much this or that device will cost depends on the number of tariffs, accuracy class, type of construction, technical characteristics. According to the rating, TM Mercury single-phase multi-tariff meters are widely popular, the price of which ranges from 5955 to 16110 rubles, depending on the number of functions performed.

A wide selection of electric energy meters TM Neva will help to make the best choice. Devices costing from 2000 rubles are very affordable. A higher accuracy class and multi-tariff affect the price of the device. The choice of electrical energy metering devices for the population is great: you can purchase equipment in the catalogs of online stores, order it with delivery directly on the site. It will cost less than in salons selling appliances related to electricity. The equipment provides the necessary documents required by law.
