System for use with a utility meter for recording time of energy use

摘要

A system for use with standard electric meters having a rotatable disc for recording time of energy use. The system includes a housing securable within a meter below the disc. The system also includes sensor means within the housing for detecting rotation of the disc and generating a signal in response thereto. Circuit means are included within the housing to process and store the signal for calculating time of energy use information. The housing also includes a communication circuit means for transmitting the time of energy use information to a location external of the meter.
