What is colloquially known as an 'electric meter', or 'electricity meter', is correctly termed an energy meter. As the name implies, an energy meter is used to measure the amount of energy (not 'electricity', which is not a quantity!) purchased from the electricity supply company for the purpose of billing its customers. This energy is measured in units called kilowatt hours (kW.h) and, for this reason, energy meters are sometimes referred to as 'kilowatt hour meters' or 'watt hour meters'.
