Single-phase meters are produced for one or more tariffs. Models differ among themselves primarily in terms of accuracy class. Also, before choosing a device, the rated voltage must be taken into account. Many modifications are equipped with a crash protection system.
The relative humidity of a good model is 30%. Additionally, when choosing a meter, you need to pay attention to the sensitivity threshold, which is measured in amperes. A good model costs about 3300 rubles.
Single tariff devices
Electricity meter (single-phase, single-rate), as a rule, is made with field-effect transistors. Many buyers choose devices of this type for simplicity and reliability. The accuracy class in this case depends on the manufacturer. On average, the rated voltage is no more than 250 V.
The tolerance parameter depends on the frequency limit in the network. In connection, the devices are quite different. As a rule, the meter is connected via terminals. In this case, the model will be able to qualitatively installonly an electrician. A single-tariff meter costs about 2800 rubles.
Two-tariff modifications
Electricity meter (single-phase, two-tariff) is in great demand. Many models are sold with the second class of accuracy. Resistors in devices are used pulse type. Atmospheric pressure for models does not exceed 70 mm Hg. Art. It is also important to note that the models are made for two terminals. Many devices have a fail-safe system. There is a high-quality two-tariff meter in the region of 3200 rubles
Multi-tariff devices
Electricity meter (single-phase, multi-tariff) is not cheap on the market. The parameters of the device are very different. Many buyers choose models for a high class of accuracy. Their sensitivity threshold is 0.2 A. The rated voltage, in turn, is 240 V. In the current circuit, the meter's power ranges from 1 to 2 watts. A high-quality multi-tariff meter costs about 3800 rubles
