A metering system provides a measuring level with multiple meters and a collection level with multiple collectors. Each meter periodically measures a parameter, such as electricity consumption, and stores measurement information. Each meter periodically transmits its stored measurement information to a collector by a wireless signal. When a collector receives a transmission, it determines which meter sent the transmission, and then extracts unprocessed measurement information. The collector then processes the measurement information to generate a metered function, such as a load profile, a time-of-use profile, or a demand profile. The collector can compensate for missed transmissions and power failures. The metered functions for each meter are transmitted from the collectors to a monitoring station.

Metering system

Device for use with utility meters to record time of use, demand and

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.

Device for use with utility meters to record time of energy use, demand

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.

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

A device for recording time of energy use for use with standard electric meters having a rotatable disc. The device includes a housing securable within a meter below the disc. A series of mounting holes are formed in the housing for mounting the device within the meter. The holes are arranged such that the device may be mounted within any standard electric meter.
