Abstract
A fuel sensing and monitoring apparatus and method is disclosed. The apparatus includes two spaced conductive coils constituting a primary and secondary winding of a transformer. A short coupling member is mounted to a movable member to which a float is attached, the float being located in the fuel tank of a vehicle. The float and movable member move in response to a change in fuel level in the tank. When the fuel level changes, the short coupling member moves relative to the primary and secondary windings. This movement adjusts or alters the transformer coupling between the primary and secondary and produces a variable output signal which can be correlated, through the use of appropriate circuitry, to a representation of the level or fuel in the tank as indicated by the position of the movable member to which the float is attached.
