Abstract
The present invention provides a retrofitting assembly and system providing automatic reading capability for gas, electric power, and water meters. The assembly includes a differential sensing system which recognizes and stores the angular position of an optical pattern mounted onto a rotating member of a meter. Light pulses stemming from pulsed sources travel through fiber optic cables on their way to the optical pattern. A Sensing/Transmitting/Receiving module generates, processes, and stores the pulses sent to and received from the optical pattern. Also disclosed is a billing system which may be built around the retrofitted or modified meters.
