ABSTRACT:
A float for a liquid level detection device has a shape with a flat surface which, when the float is in its lowermost position, will be horizontal (i.e., parallel to the liquid surface). The float has a center of buoyancy close to one edge of this face, and when the float is in its uppermost position the flat face will be generally vertical, with the edge of the face to which the center of buoyancy is closest being at the top. Because this edge is close to the center of buoyancy, only a small height of the float will project above the liquid level.
