Abstract
A system for use with polyphase electric meters having a rotatable disc for recording time of energy use. The system includes a cover, a sensor means, a first module, and a second module. The sensor means detects rotation of the meter disc. The first module is disposed within the confines of the meter cover and includes means for providing power for operation of the system. The second module is releasably mounted to the cover such that disassembly may be accomplished without the use of tools. The second module includes circuit means for determining time of energy use information and storing the same, and for optically transmitting that information to a location external of the meter.
