Abstract
A filling level sensor for a liquid container such as a fuel tank for a motor vehicle includes a lever arm having a first end on which a float is mounted and a second end mounted in a support part. A contactless magnetic sensor and a magnetic device are arranged so that the magnetic device moves in response to a deflection of the lever arm due to a change in fill level in the tank and the movement of the magnetic device changes a magnetic field acting on the magnetic sensor so that the magnetic sensor supplies an output signal corresponding to the filling level in the fuel container.
