The Magnetic Float Valve is an air sensor for detecting liquid level inside a vessel. The float mechanism mounted within the vessel operates a ceramic coated magnet. As the float moves, it pivots the magnet. A magnetically actuated sensor on the outside of the solid metal housing reacts to the inner magnet movement. The movement shifts a 3-way air valve. Both side mounted and top mounted pneumatic float valves are available either as normally closed or normally open. Normally closed pneumatic float valves produce a pneumatic output on liquid level rise. Normally open pneumatic float valves produce a pneumatic output on liquid level fall.
