Differential Pressure Monitor (DPM™)
Differential Pressure Monitoring and Shutdown System
The DPM continuously monitors the differential pressure between the inlet and outlet
of a filter monitor or filter water separator vessel. The DPM monitors the condition
of internal 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.
The DPM can also be placed in an override status in order to
conduct the required DP Gauge free movement test.
SIMPLE INSTALLATION
• Connect pressure sensors to
the existing inlet and outlet lines
on the piston type differential
pressure gauge
• Connect existing deadman circuit
loop to the DPM control unit
• Provide 12 or 24VDC to the DPM
Control unit
BENEFITS
• Low Cost
• Simple installation
• Mobile or Fixed installation
• Removes human judgment
regarding condition of filters
• Works with a variety of pressure
inputs including differential
pressure gauges, pressure
transducers and momentary
switches
• Easy upgrade to
FDPM
®
