Gas metering systems usually require pressure regulation systems (PRS) either upstream or downstream of the metering skid. PRS system is widely used in distribution lines which require for natural gas pressure reduction suitable for downstream distribution and protecting downstream pipeline/equipment from over pressure. PRS skids come with combination of Slam Shut Valve, Active and Monitor Regulators. Gas pressure regulation can be wide open monitor or working monitor based on application. Pressure set points can be adjusted either manually or option for remote set point change. Pressure regulators can be axial or globe depending on the pipe sizes and control action required and pressure drop allowed.
