Traditional Float Level Switches

Traditional float switches work by opening and closing dry contacts to send electrical signals that set off a low water level alarm. Magnetic reed switches complete the circuit when the float reaches its lowest point. The magnet then disconnects once the water has reached an adequate level again, opening the circuit up. This type of float level switch has a very limited lifespan, primarily because of the mechanical parts involved. If the float level switch fails, there will be malfunctions in the system it controls. Too little water could result in inadequate water pressure and dry running of equipment — which mean expensive repairs and problematic downtime.
