__ Application
Electromagneticflowmetersaresuitableformeasuringthe flow
ofalmostall electricallyconductingliquids,aswellassludges,
pastesandslurries.
Aprerequisiteisthat the mediummusthaveacertainminimum
conductivity.The temperature,pressure,viscosityanddensity
have noinfluence onthe result.
Thisspecialdesignofan electromagneticflowmeter(MID)is
particularlysuitableformeasuringtheflowofextremelysmall
quantitiesandespeciallyforusewith proportioningandbatching
systems.Inconjunctionwith thetransmittersIntermag
2/Transmag2,complextasks can besolvedusingtheintegral
softwareforbatchingapplications.Typicalapplicationscan be
foundinthefoodindustry,thedosingofchemicalsin
photographicsystems,andthedosingofmedicinesinmedical
fields.
When usingthealternatingfieldtechnique with thetransmitter
Transmag2,even verysmallflowscan beexactlymeasuredasa
resultofthe largermagneticfieldandthe zerostability.
The flowsensors mag-flux F5areusedmainlyinthefollowing
industries:
·Waterandwaste waterplants
·Chemicalandpharmaceuticalindustry
·Food- andbeverage industry
·Mining,cementandmineralmaterials
·Pulp- andpaperindustry
·Steelindustry
·Powergenerationanddistribution.
The flowsensorarecombinedwith thetransmittersIntermag
2/Transmag2andare only available asremoteversions.

__ Installation
The measuringprincipleisgenerallyindependentofthe flow
profile.Ideally,thedeviceshouldbeinstalledinapipeline,which
hassufficientstraight tubingbeforeandafterthe measuring
point.Ingeneral,aninletpath ofmin.5xdia.andanoutflow
zone ofmin.2-3x dia.isrequired.
Providedthatconstantturbulencedoesnotenterthe areain
whichthemeasurementtakesplace(e.g.afterelbows,during
tangentialfeedsorifthe valveinfrontofthesensorispartially
open).Insuchcasesmeasurestonormalize theflowprofileare
necessary.Suitable measuresinthisrespectare:
·increasingtheinletandoutletzones
·usingflowconditioners
·reducingthe innerdiameterofthe pipe
