Float switch sensors are essential devices for monitoring and controlling liquid levels in tanks across diverse industries, offering a straightforward and effective solution for ensuring efficient operations and preventing potential hazards or disruptions.

The float switch sensor operates on a simple principle involving a buoyant float attached to a lever or rod. As the liquid level rises or falls in the tank, the float moves up or down accordingly. 

The float is connected to an electrical switch mechanism. When the liquid level reaches a predetermined point, the float triggers the switch to either open or close a circuit, signaling the level change.
