Publication number: 20130000741Abstract: In at least some implementations, a fluid level sensor for sensing the level of a fluid within a tank includes a fluid tube through which fluid flows under pressure, a pressure pulse inducer, a fluid level responsive member and a pressure sensor. The pressure pulse inducer is disposed within the fluid tube so that at least some of the fluid flowing through the fluid tube engages the pressure pulse inducer. The fluid level responsive member is operably associated with the pressure pulse inducer to provide a force on the pressure pulse inducer that varies as a function of the fluid level in the tank. And the pressure sensor at senses the pressure of the fluid flowing through the tube, where the pressure pulse inducer induces changes in the pressure of the fluid as a function of the fluid level and the changes in pressure are sensed by the pressure sensor.Type: ApplicationFiled: June 20, 2012Publication date: January 3, 2013Applicant: TI Group Automotive Systems, L.L.C.Inventor: Lynwood F.
