In order to explore gas flow meter calibration method

study on its remote calibration technology.Describes transfer and remote calibration principle

design system architecture

develop data collection terminals and calibration software platform

and establish experimental system for test. The results show that communications between data collection terminals and platforms is good

data transmission is accurate and real-time

calibration platform calibrate instrument in experimental system and obtain expanded uncertainty of remote calibration system

which is 0. 52 %（ k = 2）

the system has practical applications feasibility.
