Abstract

A filling level sensor (2) for a fuel container (1) of a motor vehicle has two lever arms (4, 5). One of the lever arms (4) supports a float (10), while the other lever arm (5) is prestressed against the bottom of the fuel container (1). A detecting device (6) for detecting the filling level in the fuel container (1) determines the difference between the positions of the lever arms (4, 5). The detection of the filling level in the fuel container (1) is hereby rendered very accurate.
