On-Site Metrology Calibration Method for River-Piping Flowmeter

On-site metrology calibration is of practical significance and necessity to promote the rational development and utilization of water resources and to strengthen the management of water metering facilities specification. In this paper, on-site flowmeter calibration method and principle is detailed with standard instrument comparison test, deviation control range of on-site metrology calibration measurement is proposed with the application of error theory. Standard instrument reference method is proved to meet on-site metrology calibration requirements by examples analysis. Further research orientation is also put forward.
