Patent ID: 8340929

Claim:
A liquid level determination system comprising: pressure determination components; and a pressure pipe with a pressure sensing pipe end located adjacent to the pressure determination components and a bubbler pipe end locatable at least partially in a wet well, wherein the wet well is defined as a space in which liquid is collectable; wherein the pressure determination components comprise: a transducer carried by the pressure pipe adjacent to the pressure pipe sensing end for determining a pressure level within the pressure pipe, a level detection processor in communication with memory and the transducer to analyze the pressure level sensed by the transducer , a pump controller in communication with the level detection processor to control a pump locatable in the wet well; a bubbler air compressor operatively connected to the pressure pipe to provide air pressure to the pressure pipe, and an interference dampener to mitigate interference originating from the bubbler air compressor providing the air pressure to the pressure pipe.
