摘　　要：分析了采用国际标准ISO7145测量大口径管道流量时存在的理论问题和实际困难,提出了简便可靠的流量计法,论述了流量计法选择插入式流量仪表插入深度的依据。并提出了几种确定传感器系数K和选择插入深度的方法,其中包括采用流速计法。The theoritical problems and the practical dif- ficulties existing in flow measurement of large bore pipeline with the International Standard ISO 7145 are analyzed. The flow velocity me- thod with simple and reliable features is pres-ented . The basis for selecting the inserting de-pth of inserting flowmeter is described. Some measures. including the flow velocity method, for determining the coefficient K of the trans-ducer and selecting the inserting depth are stated.
