Comparison of Two Measurement Methods of Lubricating Oil Viscosity on the Spot

Liu Tao Tian Hongxiang Liu Yu(College of Naval Architecture and Power,Naval University of Engineering,Wuhan Hubei 430033,China)  
To research the accuracy and uncertainty of the measurement methods of lubricating oil viscosity on the spot,reference to the capillary measurement method of lubricating oil viscosity,the tilted tube grounder method and the tilted flat method were compared by experiments.The significance analysis and uncertainty evaluation of the measurement results were made.The results reveal that the capillary method and the tilted tube grounder method are accurate comparatively and show insignificant difference with relative expanded uncertainty under 3% while the capillary method and the tilted flat method show significant difference.
