Abstract: In order to meet the requirement of rapid development of natural gas industry, and to calibrate natural gas flowmeter used in the project of west-east natural gas transportation in China, a natural gas flow calibration station (facility) with high pressure and big diameter of pipe will be designed and built in Nanjing city. So far, the location of the calibration station, the design scheme and the process flow has been decided. The conceptual design for the facility has been completed. The main specifications of the facility are as follows: the maximum operating pressure is 5.5MPa, the maximum flowrate under actual working condition is 12000m3/h, the uncertainty of measurement is 0.5% and the maximum diameter of the test flowmeter is 400mm. The facility is composed of the primary standard, transfer standard, working standard, check standard, calibration-test section, steady pressure and flow systems. The primary standard is mass (gravimetric)-time (Mt) primary standard. The transferring standard is sonic venturi nozzles. The high accuracy of turbine flowmeters in parallel is used as for working standard. The ultrasonic flow meters are used as check standard
