Do you know the types of electric energy meters?

Older types of electric energy meters are mechanical and use a system of gears and wheels to record electricity consumption. Newer types are digital and use sensors the detect electrical power and record it in a memory device. Older meters have a clear glass dome, sort of like an oversized mason jar. Usually, there are five dials and a large rotating wheel that sits below them. These types of electric meters must be read by the owner of the property or a utility worker; they cannot be read remotely.

A digital electric energy meter has a digital readout on the meter itself and can be read remotely at the utility company's office.
