Features WORK DETAIL: When the liquid level of the container is abnormal, the alarm signal from the liquid level sensor is triggered to control the water pump to adjust the water level. SENSITIVITY ADJUSTABLE: You can adjust the sensitivity. Remove the plastic cover of the controller, turn the very small screw, reduce the sensitivity clockwise, and increase the sensitivity counterclockwise. EASY INSTALLATION: Installation is simple and convenient. The water level controller can be installed by screw positioning or electric box track. ABS MATERIAL: Made of premium ABS material, the liquid level controller is wear resistant and impact resistant, ensures long term sensitive work. WIDE APPLICATION: Relay dry node output, which can be used for various load control, such as filling or emptying oil tank.
