液体容积式流量计容量示值误差的测量结果不确定度

The uncertainty of the measurement result of the capacity indication error of liquid volume flow meter

液体容积式流量计是流量计家族中的一员,因其具有结果简单、使用方便和购置成本低廉等特性而被广泛应用于石油贸易结算,如油品的入库、成品油的批发业务等,是属于强制检定的工作计量器具。文章就液体容积式流量计现场检定/校准的示值误差测量结果的不确定度进行分析。

The liquid volumetric flow meter is a member of the family of flow meter.Because of its properties of simple resuhs, conve nient use and low acquisition cost, it is widely used in petroleum trade settlement, such as oil storage, oil wholesale business, and it be longs to compulsory verification of working measuring instruments.This paper analyzes the uncertainty of the measurement result of liq uid volumetric flow meter for the indication error of field verification/calibration.
