Abstract
The quantity of fuel being in a tank of a motor vehicle is computed in an evaluation circuit to which two primary element signals are supplied, of which one is proportional to the quantity of fuel filled in at the service station and the other is proportional to the quantity of fuel consumed. The evaluation circuit provides an output signal indicative of the difference between the fuel in and fuel consumed. Accordingly, the shape of the fuel tank does not influence the exactness of the measured value. One signal is available from which the fuel consumption as a function of time can be sensored and which is indicated at an indicator integrated into the speedometer.
