Abstract
A system and method of maintaining back pressure located downstream of the flow meter maintains the pressure downstream of the flow meter in relation to the surface back pressure (SBP). At least one flow control device is located downstream of the flow meter. The flow control device (the BPV) automatically maintains the downstream pressure to less than or equal to fifty percent (50%) of the surface back pressure. A pressure regulator sets the back pressure to allow for a standalone device. Additional valves allow adjustment of the back pressure and allow for pressure relief and full flow bypass.
