Single-phase electricity meter: price, reviews

Single-phase meters are produced for one or more tariffs. Models among themselves in the first place differ in the accuracy class. Also, before choosing a device, the rated voltage must be taken into account . Many modifications are equipped with a system of protection against failures.

The relative humidity of a good model is 30%. In addition, when choosing a counter, you need to pay attention to the sensitivity threshold, which is measured in amperes. There is a good model around 3300 r.

One-tariff devices

The electricity meter (single-phase, single-rate), as a rule, is manufactured with field-effect transistors. Many buyers choose devices of this type for their simplicity and reliability. The accuracy class in this case depends on the manufacturer. On average, the rated voltage is not more than 250 V.

The permissible deviation parameter depends on the limiting frequency in the network. The connection of the device is quite different. As a rule, the meter is connected via terminals. In this case, only the electrician can set the model qualitatively. It costs a one-rate counter about 2800 r.

Two-tariff modifications

The electricity meter (single-phase, two-tariff) is in great demand. Many models are sold with a second class of accuracy. Resistors in devices are of the impulse type. The atmospheric pressure of the models does not exceed 70 mm Hg. Art. It is also important to note that the models are made on two terminals. Many devices have a fault protection system. There is a qualitative two-tariff meter in the vicinity of 3200 r.

Multi-tariff devices

The meter of electricity (single-phase, multi-tariff) on the market is not cheap. The parameters of the device are very different. Many buyers choose models for high accuracy class. The sensitivity threshold is 0.2 A. The rated voltage, in turn, is 240 V. In the current circuit, the power of the meter varies from 1 to 2 W. There is a qualitative multi-tariff counter about 3800 r.

Comments about models «Mercury»
