Manufacturers : Optoelectronics : Energy meters
Electrical energy utilities are frequently required by state or local regulations or by energy customers to verify the accuracy of electrical energy meters operating in the field. Electrical energy meters are extensively used for measuring electric energy usage at an AC power consumer's facility. Several types of meters may be used at the facility, including demand registers, watthour meters,  time-of-use meters and tariff registers. Tariff meters or registers establish the amount of electric energy consumption for billing by the electric energy supplier. Watthour meters are used for indicating consumption in kilowatt-hours. Energy meters include two basic components: a meter chassis having a transducer which senses energy usage and produces a signal proportional to the energy usage; and a register which converts the signal into a form for accumulation and display. Programmable electronic energy meters are rapidly replacing electro-mechanical meters due to the enhanced functionality achieved using programmable logic integrated into solid-state electronic meters.
