Model FLS Floor Mount Level Switch

The Model FLS Flood Level Switch is a float operated, liquid level control designed for bracket mounting at floor level sumps or troughs.
The proven Magnetrol magnetic coupling is employed to convert float movement to actuate a single snap-action dry contact switch mechanism. The switch is factory set for 3/4" level differential for off-on control, alarm or safety shutdown service.

Operating Principle

The buoyancy force of a process liquid on the float causes the float to move with the liquid surface. The movement of the float moves an attraction sleeve into the field of the switch magnet, pulling the magnet toward the sleeve and actuating the switch.
