ABSTRACT:
A liquid level responsive sending unit is positionable in a vehicle fuel tank to deliver a signal to a fuel gage on the vehicle dashboard. An electrical damping circuit is provided on a circuit board carried on the sending unit, such that momentary fluctuations in a fuel level sensor float are smoothed out. The signal transmitted to the gage is a signal representing a time-averaged condition of the sensor. The damping circuit location in the fuel tank is advantageous as regards signal accuracy calibration, manufacturing quality control, ease of assembly, and access for component replacement purposes.
