Utility meter with wireless pulse output

摘要

An arrangement for measuring electrical energy consumption includes an input circuit operable to generate a first signal representative of a line voltage waveform and a second signal representative of a line current waveform. The arrangement further includes a processing circuit operable to generate energy consumption data based on the first signal and the second signal. The processing circuit is further operable to generate a first pulse waveform having a plurality of output pulses based on the energy consumption data, each output pulse corresponding to a quantity of energy consumed. The arrangement further includes a wireless transmitter coupled to the processing circuit, the wireless transmitter configured to transmit an RF signal each time the first pulse waveform changes state.
