Abstract: A piston-type differential pressure gauge provides an electronic output for remote monitoring. A linear potentiometer, in communication with a magnetic portion of the piston of the gauge, tracks the location of the piston. Resistance change in the potentiometer can be used by an electronic circuit to provide the electronic output of the differential pressure remotely to a data acquisition system or control electronics.

Abstract: A flow meter includes a main body having a first end and a second end, a flexible electrical resistor coupled to the main body and extending outwardly from the second end thereof, wherein an electrical resistance of the flexible electrical resistor varies in response to a flexure thereof, and an electrical circuit in electrical communication with the electrical resistor to detect a flexure of the electrical resistor.

Abstract: A passive device to neutralize electrostatic charging of fuel when it exists a filter monitor cartridge is described. Filter cartridges containing light filter media generate electrostatic charges, which flow with the fuel as it exists the filter. The device neutralizes the charges as the charges fuel exits the filter/monitor using corona discharge.

Abstract: A hydrocarbon fluid filter monitor cartridge having apparatus for neutralizing the electrostatic charge in the transient fluid including a mass of filter material, and electrical conductor having a main conductive path and a plurality of cooperating electrically conductive paths extending from the main conductive path, and means for directing the flow of hydrocarbon fluid to be treated through the mass of filter material and in contact with the conductor whereby the electrostatic charge in the transient fluid is neutralized by corona discharge.
