ABSTRACT:
A device for detecting the level of a liquid contained in a tank, for example the level of the fuel contained in the tank of a motor car. The device comprises a vertical bar inserted in the tank and a float movable with respect to the bar to follow the variations in the level. The bar, which is of insulating material, acts as a supporting element for a printed circuit having at least one continuous conductive track and a variable resistor parallel to the continuous track. On the float there is mounted a metal element which simultaneously contacts both the conductive track and the variable resistor.
