ABSTRACT:
A liquid level sensing assembly employs an inductive or magnetic coupling to wirelessly communicate a plurality of signals based on a changing level of wastewater in a tank to a first coil of a pump/alarm control circuit in the grinder pump. The assembly includes at least one liquid level sensor operable in response to the changing level of the wastewater, a second coil positionable adjacent to the first coil in the grinder pump, and a transponder for extracting electrical energy using the second coil in response to the first coil. The transponder is operably connected to the at least one liquid level sensor and operable to wirelessly transmit from the second coil to the first coil the plurality of signals based on the state of the at least one liquid level sensor due to the changing level of the wastewater in the tank.
