Quick Summary

An induction-type meter is a device used to measure and record the electric power flowing through an alternating-current circuit. These meters are commonly found on the exterior of homes.1

The meter functions like a small electric motor connected to a counter. A portion of the circuit's current powers the motor, causing its rotor to spin at a speed proportional to the current. Each rotation of the rotor represents a specific amount of power consumed. The counter tallies these revolutions and displays the total power usage, typically in kilowatt-hours.1
