1、Sensors Automation: The water level controller is reliable and when the level of the container is too low, a low level alarm signal from the low level sensor is triggered to trigger the controller to close the relay to start the pump to top up the level. When the level reaches a certain level, the high level sensor sends a signal to trigger the controller to disconnect the relay to automatically stop the pump, at which point the controller can be used to fill or empty the tank. 2、Wide Loads Application: The water pump water level controller has a relay dry contact output and can be used for a variety of loads. 3、Automatic or Manual: The liquid pump controller is versatile and can control the pump in manual or automatic mode. 4、Easy Installation: The water pump controller has low power consumption, small size, and non contact level controller is easy to install and maintain. 5、Broad Applications: This water level sensor has a three metre cable length and can be used in a wide range of scenarios.
