From August 22nd to 23rd, Dr. Li Chunhui, a traffic expert at the China Institute of Metrology, performed acceptance of the multi-purpose pVTt gas flow standard device group of the Jiangsu Provincial Quality and Technical Supervision Gas Flow Measurement Center. The deputy director of the Municipal Bureau Zhao Guoxin attended the first meeting, and the leaders of Zhou Xiaozhen, the director of the Metrology Department, and Sun Jiuchang, the head of the measurement center, attended the meeting.
Dr. Li heard a special report from the traffic center project team and checked the site. Through the experiment comparison and data review, the equipment passed the acceptance. Dr. Li commented that the device is the best device in China with the same type of five sets of devices, and the center's laboratory management is also in place and unique.
The pVTt project is a 2013 AQSIQ scientific and technological plan project, the technical indicators are: atmospheric pressure: flow (0.2 ~ 1600) m3 / h, Ur = 0.05% (k = 2); positive pressure: working pressure ≥ 0.2MPa, flow (0.5-400) m3/h, Ur≤0.1% (k=2). The device was jointly developed by the provincial center with the Shanghai Automation Instrumentation Research Institute and OVAL Corporation, a well-known foreign flow equipment company in Japan. It is not only the first in China to implement both normal pressure and positive pressure methods for the detection of sonic nozzles and real flow testing at the same time. The device of high-precision flowmeter is still the device with the largest detection range in the current international standard. International metrology committee members Raymond Richards and the United States Colorado Engineering Laboratory (CEESI) Thomas Kegel and other international experts are paying close attention to the development of provincial center pVTt projects.
After the pVTt project is completed, it can carry out type evaluation experiments on high-grade gas instruments throughout the country, carry out extensive technology research and development, and represent countries to participate in large-scale comparisons and measurement performance experiments, and will directly serve technical institutions, research institutes and petroleum aviation, etc. National key projects.
[China Instrument Network Instrument R&D] The Jiangsu Province Quality and Technical Supervision Gas Flow Measurement Center pVTt project passed the acceptance of the expert group. The project will be able to directly serve key national projects such as technical institutions, research institutes and petroleum aviation.
