Patent ID: 8843241

Claim:
A system comprising a valve configured to open or close in response to a message, the valve being coupled to the inflow port of a meter and an energy harvesting device comprising a rotor that rotates with flow of a commodity and generates electricity through electromagnets attached to a shaft coupled to or independent of the outflow of the meter, wherein the valve, meter, and energy harvesting device are electrically coupled to a processing module configured to send and receive messages to open or close the valve or send a message comprising commodity usage information from the meter and said processing module electrically coupled electrically coupled to a synchronization element, wherein the processing module is communicatively coupled to a wireless transceiver, wherein the energy harvesting device comprising a rotor that rotates with flow of a commodity and generates electricity through electromagnets attached to a shaft independent of meter shaft to overcome measurement inaccuracy at low flows due to the coupled design associated with increased magnetic flux.
