Rotary valve multi-tank indirect liquid level measurement system and method for wastewater tanks in a recreational vehicle

摘要

A multi-tank indirect liquid level measurement device and method for wastewater tanks in a recreational vehicle may be implemented using a sealable reservoir that holds pressurized air, a manual piston pump that supplies and/or pressurizes the air in the reservoir, a rotary valve that incorporates a selection disk with an axial passage that is rotationally coupled to a connection disk that has a plurality of pipes, each of which connect on their other end to the wastewater tanks to be gaged. A bourdon tube pressure gage displays the pressure difference between the sealable reservoir and atmospheric pressure, which is an indirect reading of the height of the wastewater in the tank being gaged.
