Abstract
A pressure sensor venting system for efficiently and accurately measuring a liquid level. The pressure sensor venting system generally includes a housing, a pressure transducer within the housing, a diaphragm, a pressure passage fluidly connecting the pressure transducer and a pressurized liquid from the diaphragm, and a first vent tube that is fluidly connected to the pressure transducer opposite of the pressure passage. The distal end of the first vent tube extends outwardly from the housing and extends a distance into a second vent tube. The second vent tube is fluidly connected to liquid resistant vent that is positioned within the interior space of the liquid container and above the liquid level.
