The automatic water pumping control of the water tower is realized through a photoelectric liquid level sensor. This kind of controller uses a photoelectric liquid level sensor to detect the water level of the water tower. It is mainly used to detect water shortage and full water status,and to control water pumps,solenoid valves or other instruments that need to be controlled to achieve automatic water replenishment. According to the customer's requirements,the logic functions can be changed accordingly.
The photoelectric liquid level sensor has a built-in infrared light-emitting diode and a photosensitive receiver. The head adopts a prism structure. In the water-free state,the light emitted by the light-emitting diode will be refracted into the receiving tube after passing through the transparent lens; while in the water-containing state,the light will be refracted into the liquid,so that the receiver cannot receive the light or can only receive the light. A little light.
Through the detection of the photoelectric liquid level sensor,the controller can accurately determine the water level of the water tower. When the water tower is short of water,the sensor will the in light,thereby triggering the controller to replenish the water; when the water tower is full of water,the sensor will also the in light,thereby stopping the water replenishment operation to avoid overflow of the water tower.
Water tower automatic pumping control through photoelectric liquid level sensor Accurate detection realizes automatic monitoring and control of water level. This control method is not only convenient for users to use,but also can effectively avoid overflow or water shortage of the water tower,and improve the utilization efficiency of water resources. At the same time,the prism structure design of the photoelectric liquid level sensor makes the sensor easier to clean,avoids the problem of bacterial growth,and ensures the hygiene and safety of water.
