Abstract

Advantages of an electromagnetic (EM) flow meter includes nondestructive to flow and less sensitive to flow profile. For these reasons, study on applying EM flow meters to multiphase flow measurement has been attracting researchers. A series of experiments were completed. Resistance between electrodes, gas void fraction, liquid phase mean flow speed and EM flow meters out put were measured. Relations between these data were analyzed. The results showed that certain modified factor could be used for the EM flow meter to measure water-gas two-phase flow.
