Development of a Capillary Viscometer Calibration Device and Evaluation of Uncertainty in Constant Measurement
In order to make the daily calibration of capillary viscometers more accurate,scientific,and efficient,this paper develops a capillary viscometer calibration device based on machine vision,which realizes automatic liquid level detection and improves detection accuracy and efficiency.According to the data processing rules for daily verification work and JJF 1059.1-2012"Evaluation and Expression of Measurement Uncertainty",a detailed analysis and evaluation of the uncertainty in the constant measurement of the capillary viscometer for this verification device are conducted.
