涡轮流量计测量结果的不确定度分析

Analysis of Uncertainty in Measurement of Turbine Flowmeter

涡轮流量计属于速度式流量计的一种,根据其示值误差计算方法可分为A类涡轮流量计和B类涡轮流量计,使用仪表K系数计算示值误差的为A类,使用累积流量计算示值误差的为B类。针对这两类涡轮流量计的测量结果分别有不同的不确定度分析方法。

Turbine fl owmeter is a velocity type fl owmeter, according to the methods of indication error calculation can be divided into the turbine fl owmeter of class A and class B.Of the turbine fl owmeter of class A,the indication error calculation is based on the meter K coefficient; Of the turbine flowmeter of class B,the indication error calculation is based on the accumulated flow. Of these two types of turbine flowmeter, the analysis method of uncertainty is different.
