The 101GX is simple and reliable, requiring no calibration. It is easily convertible from "normally open" to "normally closed" output contact.
The Model 101GX is specifically designed for sensing station and dry well flooding. This special purpose float switch comes fully assembled, easily mounts to a flat vertical surface (wall) and provides a field configurable normally open or normally closed contact output based on rising water levels. Float switch can detect flooding with as little as 2” of water level on the floor. It is typically used as a single alarm level sensing device in a sewage pumping station equipment chamber sump or in a process sump or water reservoir where clear water or similar liquids are present that would not foul the sliding float mechanism. Multiple float switches can be used to afford differential operation of pumps or valves.
