Abstract
An electric power consumption communicator system which includes a non-contact electric utility meter monitoring device which converts meter wheel revolutions into electronic digital pulses. An encoder device converts the digital pulses to coded electronic oscillations which are coupled onto existing power lines at the meter location. The existing power lines provide the medium for communicating coded meter intelligence to all existing power outlets in a residence or building. One or more signal decoders located at any power outlet decouple and reconstruct the coded meter intelligence into a digital format conducive to further processing.
