摘　　要：特大口径电磁流量计是一种新型的大口径水计量仪表。然而它的实流检定是制约其自身发展的关键因素。本文讨论了用标准表法检定特大口径流量计的原理 ,分析了标准流量计的误差修正 ,以期找到一种用标准表法检定特大口径电磁流量计的理想方法。Super large diameter electromagnetic flowmeter is one of the new type of water flowmeter. However its real flow verification is the key obstacle to its development. In this paper, the theory of master meter method for verification of super large diameter flowmeter is discussed and the principle of error correction of the master flowmeter is analysed, so as to get the right way of calibrating super large diameter electromagnetic flowmeter by the master meter method.
