working principle
The liquid level controller is composed of a body, a float, a flange, and a reed switch, and its structure is shown in the figure. Working principle: The liquid pushes the float, and the magnet in the float causes the reed switch to close and control the intermediate relay, and then the intermediate relay pushes the contactor to control the liquid inlet motor to keep the liquid level within a certain range, thereby achieving the purpose of automatic control.
