This Smart Small Size Plastic Water Flow Switch is produced by plastic material, used in Sea Water Heating System, Water Purification Equipment, Welding Equipment, Laser System, to measure or control the flow rate. The Magnet don't stay in the flow, so the magnet will not contact with the rust of the water flow, so could make sure the water flow switch will be stability. International Protection could be IP68 (Optional).

GE-312A only have a plastic magnet inside the body, it have less component, so it will be very stability. 
GE-312C is piston flow switch, it could installed by any position.
