摘要

Liquid level indicator device in fuel tanks, particularly applicable to flat vehicle tanks, of the type comprising a hollow cylindrical body, equipped with small fuel inlet and outlet openings, through which it moves upwards an upper and lower stopper, a float floating on the surface of the fuel, also being arranged inside the hollow cylindrical body an electrical resistance on which a conductive element that co-operates with the said electrical resistance in the formation of a variable resistance depending on the level of the fuel, said hollow cylindrical body being closed at its lower part by a cover provided with a fuel filter and at its upper part by an upper head, and said body being traversed by a suction pipe of the fuel, which also passes through the lower cover and the upper head or, characterized in that between said upper stop that determines the end of stroke of the upward displacement of the float and the upper face of the latter, at least one spring is provided that works in compression, tared so that the float reaches said upper stop at the exact moment when the liquid level reaches its maximum level, the float then starts to descend as soon as the liquid level also starts to fall, thus increasing the range of measurable levels in the upper part of the tank, due to the effect of variable float level in the float.
