CL-1-4S-QK type is specially designed for high pressure gas storage, which is suitable for transfer metering of natural gas trade and unconventional gas (Methane gas, coal bed gas, shale gas) trade with four path configurations which could carry out accuracy measurement of natural gas and has good adaptability to intermittent flow, full flow, whirlpool flow, pulsating flow and other unstable flow fields of gas. The measuring bores ranges from DN50~DN400 and the working pressure covers from 0.1MPa to 26MPa (higher working pressure could reach 40MPa) with 0.5 class accuracy.
