A display device also includes an available amount-of-fuel calculator for calculating an available amount of fuel, an average mileage calculator for calculating an average mileage from a consumed amount of fuel and a vehicle's traveled distance, an available travel distance calculator for calculating an available travel distance from the available amount of fuel and the average mileage, and a display unit for displaying the available travel distance. The available amount-of-fuel calculator uses a learned value based on outputs as a corrective value for correcting the output of a second sensor when the calculation of the available amount of fuel switches from being based on the output of the second sensor to being based on the output of a first sensor.

A method for adaptive calibration of a fuel level indicator of a filling level of a liquid in a tank accompanying operations. A filling level of the liquid is detected with a sensor arrangement. A sensor signal of the arrangement is provided during a movement of the vehicle. In case that the course of the sensor signal is obtained in a respective defined time interval in which the sensor signal is provided several times, a constant value is assumed, an end stop is detected. The respective time intervals at which the end stops were detected and the respective associated constant values are stored. A minimum number of end stop is defined for the tank, and in the case that the minimum number of end stops is reached, a calibration phase is carried out.

A liquid surface detecting device includes a movable body, a circuit board, segment electrodes, an output electrode, and a resistive element located across the segment electrodes and the output electrode to be electrically connected thereto. The segment electrodes are arranged on the mounting surface in an electrode region. The resistive element includes first and second resistive portions on both sides of the electrode region in the movement direction. The resistive element is electrically connected to the output electrode at each of the first and second resistive portions. The movement direction in which the movable body moves according to a decrease of the liquid surface level is defined as a reference direction. The second resistive portion located further in the reference direction than the first resistive portion is completely cut off to block a conduction between its output electrode side and electrode region side.
