A magnetic float assembly is provided, comprising (i) a generally cylindrical paramagnetic (e.g. stainless steel) float enclosure having first and second closed end portions located at opposite ends of a longitudinal axis running the length thereof, and having a generally cylindrical interior surface located between the end portions, (ii) a first annular magnet disposed within the float enclosure at a first location along the longitudinal axis and having an outer surface which substantially corresponds to the generally cylindrical interior surface, and (iii) and a second annular magnet disposed within the float enclosure at a second location along the longitudinal axis and having an outer surface which substantially corresponds to the generally cylindrical interior surface. The first and second annular magnets are separated by a paramagnetic (e.g. aluminum or titanium) spacer. Ends of the first and second annular magnets facing each other are magnetized in one polarity and ends of the first and second cylindrical magnets facing the end portions of the enclosure are magnetized in an opposite polarity. The magnetic field of an operating pole of the assembly is created by the proximity of like-charged portions of the facing magnets, and is directed radially outward of the longitudinal axis of the float enclosure toward the outside of the enclosure.
