RMG 655-DP is the operator of the gas level system. The device is a standard air pressure control pneumatic pilot machine. The unit can be used to regulate the exit and the differential pressure (to control the flow through the downstream surface orifice). RMG 655-DP is also a lightweight driver capable of measuring differential pressure rates. Pilot is an integral component of this unit with input strain, loading pressure gages and upstream RMG 905 fine-mesh filter, often available with output pressure gauge (optional) Optionally RMG 915 ventilator valve appropriate for non-aggressive gases, other gasses in the PED CE enquiry list in combination with RMG Gas Strain Regulators.
