Abstract
Some embodiments may include a system for determining a filling level of a fuel situated in a fuel tank comprising: an air pump; a valve; a pressure sensor; a control unit; a timing element; and a control unit. The control unit may be programmed to actuate the valve to close the fuel tank and subsequently actuate the air pump to increase a pressure in the fuel tank until an upper threshold is reached. The timing element may determine the time required for the pressure to reach the upper threshold. The control unit may calculate the filling level of the fuel based on the time taken to reach the upper threshold.
