When the liquid level inside the tank changes, the float swings with the rise and fall of the liquid level, triggering an internal magnetic switch to output a switching signal, thereby realizing high and low level alarms and pump start/stop control.

What’s The Working Principle Of Horizontal Float Level Switch?
The Horizontal Float Level Switch operates on the principle of buoyancy and is installed on the side of the tank via a threaded/flange. When the liquid level inside the tank changes, the float swings with the rise and fall of the liquid level, triggering an internal magnetic switch to output a switching signal, thereby realizing high and low level alarms and pump start/stop control.
Widely Application Of Side Mounted Level Switch:
The Horizontal Float Level Switch is widely used in level monitoring of storage tanks and reaction vessels in industries such as chemical, water treatment, petroleum, shipbuilding, food and pharmaceutical. It does not continuously measure liquid levels, has a simple and reliable structure, and is suitable for various corrosive and ordinary liquid conditions.
