Velcon Filtration Division, a Parker Hannifin Company

Differential Pressure Module - DPM™

The DPM control unit continuously monitors the differential pressure between the inlet and outlet of a filter monitor or filter water separator vessel. Whether static or onboard hydrant carts or refuelers, the DPM monitors the condition of the filter elements. In the event that the filter differential pressure reaches maximum allowable pressure, the industrial strength relay onboard the DPM control unit breaks the deadman circuit, effectively terminating the refueling operation.
