The meters can be used both for direct measurement of amount of the electric power, and as initial gauges for the automated systems of the account of the electric power.

The meters have strengthened protection against the non-authorized external influences: magnetic fields, mechanical influences, from larceny of the electric power. In the meter is used the stopper of reverse motion, or the reversive accounting device.
