Abstract:

This study introduces a calibration software system applied to the gas flow standard facility with master meter method. In view of the complicated design of programming software such as MFC and C#, this study uses configuration software with simpler programming as the development environment, and designs a set of calibration software to realize the functions of data collection, process visualization display, calibration data storage, calibration report generation and calibration historical data query during the gas flow calibration process of the standard meter method. The actual environment test shows that the software can be competent to monitor the flow calibration. The error of the calibrated value is within ±0.2%, and the repeatability is below 0.02%, which is consistent with the previous calibration certificate data and meets the 0.2-level accuracy turbine flowmeter national standard. After the uncertainty evaluation, the system uncertainty is below 0.4%, which meets the requirements of the standard facility.

Key words: software design, host computer, configuration software, flow standard facility, master meter method, flowmeter calibration, uncertainty, process control
