ABSTRACT:
A level transmitter for liquid containers, particularly fuel store tanks, comprising a housing in which a contactless sensor is arranged which is connected with an evaluating unit and operatively connected with a magnet that moves relative to the sensor when a float arranged at a first end of a lever moves so that the change of the magnetic field acting upon the sensor is transformed into an electric signal so that an output signal corresponding to the level of the liquid in the container is obtainable by the evaluating means. The magnet is configured at least as a segment of an annular magnet that is arranged at a second end of the lever and integrated therein.
