世界最大的磁感应流量计(MID)的流体检定装置可能已于1979年在荷兰 Sliedrecht 投入运行。建立在标称管径为350～3000mm 基础上的这种装置的测量误差<±0.05%。该年四月底,用这一装置检定目前最大的标称管径为
The world’s largest magneto-inductive flowmeter (MID) fluid verification device may have been put into operation in 1979 in Sliedrecht, the Netherlands. The measurement error of this device based on the nominal diameter of 350 ~ 3000mm is less than ± 0.05%. At the end of April of this year, the maximum nominal pipe diameter for the current test was determined with this device
