Automatic display liquid level controller 122 * 61 * 41 (mm)

Characteristics of automatic display liquid level controller
1. Non electrode detection of liquid level avoids contaminating water sources and preventing poor contact caused by electrode corrosion.
2. Only two wires were used to achieve four point water level display, achieving extremely high cost-effectiveness.
3. Adding a detection head can achieve water source water shortage protection function, avoiding pump idling caused by water source water shortage.
4. It has automatic and manual functions, fully considering the convenience of user use, simple installation, and low maintenance workload.

Working principle of automatic display liquid level controller:
This controller consists of a water level detection part and a display control part. The water level detection part is installed on the reservoir, and the display control part is installed at the place where the water level needs to be observed or the water pump (or solenoid valve) needs to be controlled. When there is no water in the pool and the controller is powered on, press the manual button to start the water pump to inject water into the pool. As the water level in the pool rises, the corresponding indicator light will light up. When the fourth light is on, indicating that the water level in the pool has reached the upper limit, the water pump will stop working. Later, as the water level in the pool decreases, the indicator light will turn off. When the first light goes out, the controller will start the water pump to inject water into the pool again. From now on, it will work in a loop without the need for human intervention. When encountering special circumstances that require water supply, the water pump can be started by pressing the manual button.
