The device has a filling level sensor (2) designed as an ultrasonic transmitter and comprising a floating unit (3). A state space system is determined and a tank volume value and a tank filling level value are subsequently determined by using a Kalman filter. A tank filling level sensor values is subsequently filtered. A tank filling level is continuously determined as a function of a mathematical relationship between the tank volume and filling level values and independent of a type of the filling level sensor, a switching state and ultrasound. An independent claim is also included for a method for determining a tank filling level value of a moving vehicle. |
