ABSTRACT:
Liquid level sensing means comprising galvano-magneto effect transducing means, magnet means for applying magnetic flux to the transducing means, switching means movable with respect to the transducing means and having an influence on the magnetic flux applied from the magnetic means to the transducing means so that an electric signal is produced by the transducing means when the switching means has passed by the transducing means from one side to the other side thereof, one of the transducing means and the switching means being held stationary, and the other being movable in accordance with a change in liquid level.
