Metrology Institute of Yunnan Province to complete "liquid displacement method of gas flow standard device" developed that
Measurement of small gas flow to further enhance the level of
After 3 years of research, recently undertaken by the State Metrology Institute of Yunnan Province General Administration of Quality Supervision, Inspection Project "Replacement of liquid gas flow device" to complete the development.
Currently, the hospital completed the installation and commissioning of equipment and experimental work, the technical indicators have reached the requirements of the mission statement of scientific research, the successful development of devices will enhance the overall level of China's small and medium gas flow measurement, while the gas flow meter for the independent innovation of China R & D capability to provide technical support.
According to reports, Yunnan Province, the researchers measured the daily hospital Verification / calibration work, the certification process for small and medium gas flow problems are explored, developed a simple theoretical method of installation. Flow test in 2006 in the National Conference on Academic Exchange preach the "Replacement of gas flow standard device of a" preliminary research paper, by theoretical methods of early access to a scientific test methods and models. In 2008 the hospital made to the State Administration of Quality Supervision, "Liquid Replacement gas flow standard device" developed by the research projects and projects approved by the Administration. In the same year, "Gas flow device testing device" to obtain a national utility model patent certificate (patent number is ZL2007 2 0105236.7).
Through the tireless efforts of the hospital scientists, November 2010, the device reaches a predetermined the technical requirements to achieve the level, temperature, humidity, pressure, time, quality, automatic acquisition and control, image calibration data was the automatic acquisition, can automatically static and dynamic test test, test data is automatically stored in the database. Accuracy of the entire package of up to 0.2 (replacement of some equipment and improving environmental conditions can reach 0.05), the gas flow rate measurement range: (0.1 ~ 250) L / min, up to 2500:1 turndown ratio for the national initiative. "Liquid Replacement gas flow device of" traceability of the gas flow to the accuracy and reliability of the quality of the value and improve the gas flow meter test / calibration accuracy and reliability, stability control to overcome the problem of gas flow to meet the social and economic construction of medium and small gas flow rate precision detection.
