Research on the Flow Measurement Error Model of the Diverter in the Liquid Flow Calibration Facilities
摘要
Abstract
To overcome the error calculation difficulties of the diverter in the liquid flow calibration facilities, the limitations had been analyzed in the uncertainty model of the diverter at present. Based on considering the diversion damper situation and the jet flow velocity profile,a measurement error model of the diverter was developed in which the different location of the damper in the mid-travel was considered. The measurement error brought by the diverter was calculated based on the new measurement error model. Calculated results show that, the establishment of the new measurement uncertainty model of divert about the diversion damper situation was reasonable and could meet the error calculation of the divert.关键词
