Device for measuring filling level of liquid in container, particularly for oil-lubricated engine in motor vehicle, has evaluation unit is aligned in such way that corrected filling level is determined,

摘要

The device has a damping cup (2) and an ultrasonic sensor (16) arranged in a lower area of the damping cup, where the filling level (4) of a liquid (3) is determined from the run time of an ultrasonic signal in a measuring distance (8) of the damping cup with an evaluation unit. The evaluation unit is aligned in such a way that a corrected filling level is determined, where data is provided from the different run times of ultrasonic signals in the separated reference measuring distances (12,13), which result from the inclination of a surface (5) of the liquid in relation to the damping cup.
