It includes a robust and accurate embedded differential pressure sensor, which can survive a pressure of up to 18 bars. The DP INDUSTRIAL signals the irrigation controller with a dry contact (Any model) that the differential pressure is above the permitted value so it can begin to backflush. Programming is done easily with the Dipswitches.

The standard power option for the DC version is 12V DC from the irrigation controller. If the irrigation controller cannot supply 12V DC, It can also be powered by a 12V DC power supply or a small solar panel and a small rechargeable battery.
