摘要
通过钟罩式气体流量标准装置对膜式燃气表的容量示值误差进行测量不确定度评定,找出影响膜式燃气表容量测量结果不确定度的主要因素以对其实施有效控制。
The uncertainty evaluation of capacity indication error measurement of diaphragm gas meters is made by using the bell-type gas flow standard device, trying to find out the cause of capacity indication error measurement uncertainty of diaphragm gas meter and the effective control over it.
