Abstract
A float for a liquid level gauge mechanism is disclosed, along with the mechanism with which such float is used. The float takes the form of an elongated hollow body of approximately the same weight or lighter than the weight of an equal volume of the liquid involved. The elongated body has first and second ends with the first end being heavier than the second and being the end to which the filament of a spring-operated reel is connected. In a preferred embodiment, the difference in weight between the first and second ends approximates the retraction force exerted upon the filament by the spring-operated reel.
