Overview Intelligentelectromagneticflowmeterisoneinductioninstrumentformeasurementofvolumeflowrateofconductingmedium. BasedonelectromagneticinductionprincipleofFaraday,onepairofelectrodesismountedonthepipewallwhereaxisofsounding pipeisperpendiculartomagneticline.Whenconductingfluidmovesalongwithaxisofsoundingpipe,conductingfluidgenerates inductionpotential,whichischeckedoutbytwoelectrodes,whosevalueisproportionaltotheflowrate. Apartfrommeasurementofvolumerateofgeneralconductingfluid,theycanbeusedformeasurementofstrongcorrosivefluid includingstrongacidandstrongalkali,andvolumeflowrateofevenliquid-solidtwophasesuspensionfluid.
