Abstract
A utility meter comprises an electromechanical metering portion connectable to a power drop to a premises and an electronic portion coupled to the electromechanical portion. The electromechanical portion comprises a rotating disk portion rotating at speeds proportional to power flow through said meter. The electronic portion comprises an interface coupled to the rotating disk, a controller coupled to the interface for accumulating power usage data over predetermined intervals, a memory coupled to the controller for storing power usage data, and a modem interface for coupling the controller to a public network. The controller is programmably operative to automatically establish a connection via the modem interface for uploading power usage data stored in the memory.
