Research on Technology Status and Development Direction of Large Diameter Water Flow Standard Facility in China
Abstract
The performance of large diameter water flow facility will have a direct impact on the accuracy and value uniformity of detected flowmeter measurement results. In addition, ensuring the stability and reliability of facility performance has always been a key link in the traceability and transmission of value of large water flow. However, the application scale and measurement capability of existing large diameter facilities are difficult to fully meet social needs. In this paper, based on National Institute of Metrology (China), provincial metrology institutes and related flow enterprises, focusing on the domestic typical large diameter water flow standard facility has been built to carry out the investigation and research, comparative analysis of different types of device structure principle, measuring ability, technical characteristics and the regional distribution, etc. Based on this, the key technologies that may emerge in the field of large diameter water facility in the future are explored and the future development trend is summarized. The relevant research results of this paper have important practical significance for improving the measuring capacity of domestic large water flow facilities, standardizing and improving the construction of traceability system for large water flow measurement.
