1. An electric meter comsumption and demand communicator system for use with a Watt hour utility meter of the rotational disc type, for metering an AC power line, said communicator system comprising in combination: power line encoder-coupler circuit means for extracting power from the AC power line within the meter or adjacent thereto to establish a DC power source and including non-contact power consumption and demand monitoring means deriving current from said meter disc and pulse initiator means effective to generate electronic digital pulses in a predetermined relationship to the number of rotations of the disc, signal generator means electrically connected to said pulse initiator means for producing high frequency coded electric signals corresponding to said digital pulses and connecting to the AC power line of the meter system for inducing said signals upon said power line; and power line decoder-decoupler circuit means connecting to said AC power line for extracting said high frequency electric signals and restoring said electric signals into digital pulses.
