Description
Electricity Meter also called quantitative watt-hour meter, IC card watt-hour meter, not only have the functions of ordinary watt-hour meter measuring, in particular the user to buy electricity, buy electricity to electricity, if use after the electricity users do not continue to buy electricity, automatically cut off the power to stop the power supply
