Water Level Sensor and Controller KitThis Water Level Sensor and Controller Kit can be used with the BREWHA Touchscreen Controllers (1. 5 15BBL Controllers) to automatically turn the pump off when water levels drop low (below the sensor). Additionally wiring is not needed inside the controller as the controller comes prewired for the level sensor. Just plug the controller box into the level sensor base inside the controller, and connect the level sensor to the 'Level Sensor' receptacle
