The Fully Automatic Water Level Controller Circuit Board with Dry Run Protection is an innovative and essential device for effectively managing water levels in overhead tanks and sump pumps. Designed for hassle-free operation, this circuit board integrates advanced technology to ensure the safe and efficient usage of water in various settings. The board features a compact design, measuring approximately 9.5 x 6.5 cm, and comes pre-assembled for immediate use. It requires minimal setup, necessitating only two vertical or side-mount magnetic float switches and a dry run sensor for optimal functioning. Built with safety in mind, it utilizes float switches to prevent any electric current from flowing into the water, eliminating risks of chemical reactions and corrosion. The controller automatically turns off the motor when water reaches the top level or when no water is detected flowing into the overhead tank, promoting efficient water usage and saving both time and energy. The included LED indicators display power, motor status, and water levels, ensuring users are always informed about the system’s operation. Additionally, it offers a manual/auto switch option, giving users greater control over their water management needs. This advanced water level controller is particularly advantageous for enterprises seeking an efficient, low-cost solution to water management while reducing the need for continuous manual monitoring.
