ABSTRACT:
A device for detecting the amount of liquid in a vessel, such as a fuel tank of an automobile, using a torsion support member such as a torsion bar arranged between the vessel and the body of the automobile. The torsion displacement of the member corresponding to the amount of the liquid is detected in a detection circuit and processed in an electronic unit which includes a portion for generating a pulse width signal corresponding to the amount of the liquid on the basis of signals from the detection circuit, a portion for generating a signal having a pulse number proportional to the pulse width on the basis of the generated pulse width signal, and a portion for averaging at predetermined intervals the value corresponding to the pulse number of the signal from the pulse width detection portion using timing pulses generated at predetermined intervals and for displaying the average amount of the liquid digitally on a display portion.
