Patent ID: 7409860

Claim:
A fuel level measurement device for a fuel tank comprising: an arm having one end configured to be carried pivotally by a body and a distal end; a float housing carried by the arm adjacent the distal end and defining a sealed chamber providing buoyancy generally upon a surface of fuel in the tank; a cupped track carried by the housing within the chamber and opening generally upward; a gravity responsive, electrically conductive, member that changes position along the track with changing elevation of the float housing; an electrical conductor exposed in the chamber and extending along the length of the track; a variable electrically resistive ink strip exposed in the chamber and extending along the length of the track; and the gravity responsive member is in movable electrical contact with the resistive ink strip at a first point and in movable electrical contact with the electrical conductor at a second point to provide an electrically conductive path generally of the member and between the ink strip and the conductor for electrical circuit completion.
