Meter skid/Pressure Reduction System, also known as a metering skid, is a framed device on which various assemblies are installed. These include meter prover loops, control valves, meter runs and ancillary control houses to name a few. The main use of a meter skid is as custody transfer meter, whereby it is used to determine financial estimates. Every meter skid can be composed of the process gas chromatograph and one or more flow meters. The meter skid also measures the gas and decreases the pressure of the gas at metering stations.

These skids are used to reduce upstream pressure & control flow suiting the downstream requirement. Most common use is Nitrogen Pressure Reduction, Natural Gas Reduction Pressure Reduction etc.
