The theory of unit element indirect calibration is introduced by this paper by the key parameters of unit element indirect calibration is how to precisely measure the induced electromotive force in the low cost cases. The relationship of measurement error between electromagnetic flow meter and small measurement tube was analyzed in detailed, and the specific expression was given. The comparison experiment was made between unit element indirect calibration and actual flow calibration; experimental results show that the analysis of small measurement tube precision is credible.
