The compressed natural gas pressure regulation and metering system (CNG PRMS) mounted on a skid reduces pressure from 25 MPa to 0.4 MPa within a plug-and-play unit. It offers a flow range of 30 to 10,000 m³/h with metering accuracy of ±1.5%, supports remote 4G monitoring, and features a CE/ASME steel construction. Deployment speed at gate stations, industrial sites, and LNG satellite stations increases by 70%, enabling unmanned operation and stable performance.
