Abstract
An electrical energy consumption meter for use on a consumer's premises has data processing means responsive to the sensed voltage and current and to data such as tariff rates and clock information, for computing and displaying charges in monetary terms. A data link with the utility enables the utility to make use of this information and to add hire purchase commitments, etc. to the charges for energy consumption and also to enter credits for payments received. The data link may include provision for credit transfer by the consumer. Coin or token prepayment facilities may also be provided.
