The solved method and correction installation of the problem was also studied. The installation could detect the magnetic susceptibility and conductivity of polymer solution online by the theory of electromagnetic induction. The detection signal processed by computer could directly reflect the true flux and total volume after correction, and the installation could also detect the quality and dissolving level of polymer solution online. It was found that the solved method and correction installation could enhance the measure precision of electromagnetic flowmeter, and revealed the quality variation of polymer solution. Keywords: measure of polymer solution flux, measure error of electromagnetic flowmeter, correction of flux measure error, detection techniques of electromagnetic induction, quality detection of polymer solution online
