Abstract
A water pit transponder assembly includes a housing with multiple sections including top, main and bottom sections snap latched together connected to a water meter. A circuit board transponder in the housing includes a controller, a transmitter, a receiver and tamper detection software connected to antennas. An encoder is connected to the water meter, and batteries provide power to operate the assembly. The transponder sends and receives at different frequencies through different antennas and is protected from environmental corrosion by being encapsulated in a get inside the housing.
