What is a float switch and how does it work with a submersible pump?
A float switch is a type of device that detects the level of liquid within a tank, providing an automated way to manage fluid levels. It operates on a simple principle: as water levels rise or fall, the float (a buoyant object) moves up or down. When the liquid reaches a predetermined level, the float switch activates or deactivates, sending a signal that turns the connected pump on or off.
In the context of a submersible pump, this integration helps maintain optimal liquid levels in a sump or reservoir. When the float switch is activated by high water levels, it triggers the pump to start working, removing excess water and preventing overflow. Conversely, when the water level drops to a certain threshold, the float switch turns off the pump, thereby conserving energy and preventing potential damage from running dry.
