Overview of 10 types of best energy meters: how to choose which one to buy, the pros and cons, features, rating

The electricity meter is an essential tool of any modern grid. It can be used keeping produce electrical energy.

How to choose the electricity meter

When buying electricity meter isolated following selection criteria:

• The number of tariffs. The most common - one tariff and dual-rate model. Two tariffs are necessary to save (at night Energy costs are lower than during the day). Devices with a single tariff of such a possibility does not have.
