Abstract
A liquid-level sensor provides a downwardly pendent float supported above the reservoir fill height using high clearance downwardly extending fingers and a spring that resist encrustation of the float support mechanism. The spring may be a flat helix to reduce the height of the sensing mechanism when so positioned. A sensor sealed within a sensor head electrically senses the float height through a sealed compartment to be contamination resistant.
