DP-09 is a Digital fully Automatic Pump Controller or water level controller which comes with a water level sensor of the overhead tank only. If you are using borewell water and do not have an underground reservoir then this product is suitable for you. It is suitable for the single or three-phase motor and any starter panel. It continuously monitors the liquid level of the overhead tank. The Automatic pump controller controls the pump and turns it ON and OFF with respect to the level in the overhead water tank. This auto-switching feature saves manpower. Hence no need to operate the pump manually on daily basis. Our system switches the pump ON when the level of water in the tank goes below LOW level and OFF when the water touches the HIGH level. Thus no wastage of water, stop tank overflow, save water, electricity bill, time and water charges.
