In a liquid-level transmitter having a swingable support lever (3) which bears a float (7) and a variable electrical resistor (9) actuated thereby, the variable resistor (9) is surrounded by a bell-shaped structural part (1) which is open towards the bottom but otherwise closed. In this way, as in the case of a diving bell, no liquid can enter into the bell-shaped structural part (1) when the level of the liquid rises above the height of the liquid-level transmitter, so that parts of the variable resistor are protected in simple fashion from corrosion due to contact with the liquid to be measured.

In combination in a fuel tank a liquid-level transmitter comprising a pivotally supported lever which carries a float and is operatively connected to a contact of a wiper which is movable along an electrical resistor upon pivoting of the lever, the improvement comprising a housing formed as a bell-shaped structural part having an opening located at the bottom and being sealed off at all other portions thereof, the wiper and the electrical resistor being disposed in said bell-shaped structural part, and wherein all portions of said resistor are supported within said housing at a sufficient distance above said opening so as to inhibit wetting of the resistor by the liquid during a raising of the fuel liquid level in the fuel tank, and wherein said wiper is supported at a mounting on said housing, and extends from said mounting away from said opening for contacting said resistor.
