Introduction:
Chengdu Verification Branch for Natural Gas Flow Meter of National Crude Oil Large Flow Measurement Station is a legal measurement verification organization authored by the General Administration of Quality Supervision , Inspection and Quarantine of the People's Republic of China, and is supported by the PetroChina SouthWest Oil & Gas Field Company. The branch takes on the mission of the verification and calibration for the natural gas flow meter in its authored area (overall China), and also engages in the natural gas measurement technology research, standard and regulation drawing and editing. There are one set of mass-time(mt)primary standard, one set of critical flow nozzle secondary standard and one set of mobile gas ultrasonic meter working standard in the branch.. The maximum working pressure, mass flow range and total uncertainty of the primary standard are 4.0 MPa, (0.005~2.47)kg/s and 0.1%. For the secondary standard, the maximum working pressure, actual volume flow range and total uncertainty are 4.0 MPa, (5~5115)m3/h and 0.25%. The working standard can be served in the field and its maximum working pressure, actual volume flow range and total uncertainty are 6.0 MPa, (80~8000)m3/h and 0.35%~0.5%. 5 kinds of natural gas flow meter are authored to verified and calibrated in the branch, they are critical, differential pressure type , velocity and volume flow meter.
