Description: Material: The Automatic Water Level Controller is made from Fireproof materials for security and durability.Dimensions: With dimensions of 115mmx90mmx40mm, this Water Pump Controller can be easily installed.Product Features: The Non contact High and Low Level Controller comprises two liquid level detection heads and a controller. It can automatically control the high and low levels of liquid in a container. When the liquid level is too low, the low level sensor sends an alarm signal to the controller, which then activates the pump to add more liquid. Once the liquid reaches a certain height, the high level sensor spark a signal to stop the pump automatically, thus maintaining a stable liquid level in your container.Wide Applications: This automatic water level controller is suitable for automatic water replenishment in water tanks, barrel, and towers; intelligent control of water pump and solenoids valves; water control in aquariums; and monitors of liquid levels in automated industrial equipment.Package Includes: 1 Automatic Water Level Controller.
