DPMDesigned to comply with the JIG Bulletin No.58, the Velcon DPM is an all inclusive differential pressure monitoring and shutdown system.

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. The system can only be overridden by inserting a supervisor key as specified by the JIG No. 58 bulletin. The DPM can also be placed in an override status in order to conduct the required DP Gauge free movement test.
