Abstract :
The paper deals with working principle and design methods about gas flow standard facilities by master meter method. A wind tunnel was designed to work as the flow velocity measurement and calibration platform. The distribution of the facility uncertainty was calculated. And finally the test results of the facility performance were given including the effect of the wind tunnel on the airflow, the impact of the humidity on the air density in the pipe and the flow-meter coefficient and the calibration of orifice flow-meter.
