meter

A device used to measure and record one or more quantities at a meter point. Meters can store the measured and recorded quantities either electromechanically (in the form of physical dials and needles) or in an electronic memory, or both. For meters that store recorded and measured quantities electromechanically, the meter's physical characteristics determine the numbers and types of quantities it can store. For meters that store recorded and measured quantities electronically, the meter's programming determines the numbers and types of quantities it can store.
