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，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，分析了温度对标准表法流量检定装置的影响，提出了误差修正方法和对检定装置设计的要求．
Super-large diameter electromagnetic flowmeter is one of the new types of water flowmeter. Howerer its real-flow verification is the key obstacle to its development. In the thesis the theory of master meter method for verification of super-large diameter flowmeter is discussed and the temperature influence on the calibration rig with method of master meter is analysed. It is tried to find the method of error correction and to propose design requirements.
