4.TransducerInstallation
4.1. InstallingtheTransducers
Beforeinstallingthetransducers, cleanthepipesurface wherethetransducersaretobemounted. Removeanyrust,
scaleorloosepaintandmakeasmoothsurface.Applyawidebandofsoniccouplingcompounddownthecenter
oftheface ofeachtransduceraswell ason thepipesurface,and thenattachthetransducerstothepipewiththe
strapsprovidedandtightenthemsecurely.
Note:
Thetwotransducersshouldbemountedatthepipe’scenterlineonhorizontalpipes.
Makesurethatthetransducermountingdirection isparallelwiththeflow.
Duringtheinstallation,thereshouldbenoairbubblesorparticlesbetweenthetransducerandthepipewall.On
horizontalpipes,thetransducersshouldbemountedinthe3o’clockand9o’clockpositionsofthepipesection in
ordertoavoidanyairbubblesinsidethetopportionofthepipe.(RefertoTransducerMounting).Ifthe
transducerscannotbemountedhorizontallysymmetricallyduetolimitationofthelocalinstallationconditions,it
maybenecessarytomountthetransducersatalocationwherethereisaguaranteedfullpipecondition(thepipeis
alwaysfull ofliquid).
4.1.1. TransducerSpacing
Afterenteringtherequiredparameters,thespacingbetweentheENDSofthetwotransducersisconsideredasthe
standardtransducerspacing(RefertoTop Viewontransducermounting methods).Checkthedatadisplayedin
WindowM25 andspacethetransducersaccordingly.
4.1.2. TransducerMounting Methods
Fourtransducermountingmethodsareavailable.Theyarerespectively:Vmethod,ZmethodandNmethod.The
Vmethodisprimarilyusedonsmall diameterpipes(DN100~400mm,4”~16”).TheZmethodisusedin
applicationswheretheVmethodcannotworkduetopoorsignalorno signaldetected.Inaddition,theZmethod
generallyworksbetteronlargerdiameterpipes(overDN300mm, 12”)orcastiron pipes.
TheNmethodisanuncommonlyusedmethod. Itisusedonsmallerdiameterpipes(belowDN50mm, 2”).
4.1.3. VMethod

4.2. TransducerMountingInspection
Checktoseeifthetransducerisinstalledproperlyand ifthereisanaccurateandstrongenoughultrasonicsignal
toensureproperoperationandhighreliabilityofthetransducer.Itcanbeconfirmedbychecking thedetected
signalstrength, totaltransit time,deltatimeaswell astransit timeratio. Thesechecksareexplainedbelow.
The mounting”conditiondirectlyinfluencestheflowvalueaccuracyand systemreliability.Inmostinstances,
applyawidebeadofsoniccouplingcompoundlengthwiseonthefaceofthetransducerandstickit totheoutside
pipewall togetgoodmeasurementresults.However,thefollowinginspectionsstillneedtobecarriedoutinorder
toensureahighreliabilityofthemeasurementandlong-termoperationoftheinstrument.
4.2.1. Signal Strength
Signalstrength(displayedinmenu 90)indicatesadetectedstrengthofthesignalbothfromupstreamand
downstreamdirections.Therelevantsignalstrengthisindicatedby numbersfrom00.0~99.9. 00.0 representsno
signaldetectedwhile99.9 representmaximumsignalstrength.
Normally, thestrongerthesignalstrengthdetected, thebetterthemeasurement.
Adjustthetransducerspacingtothebestpositionandchecktoensurethatenoughsoniccouplingcompound is
appliedduring installationinordertoobtainthemaximumsignalstrength.Thisisessentiallyfinetuning the
calculatedspacingshowninmenu25 (transducerspacing).Itmaybeslightlydifferent.
Systemnormaloperationrequiressignalstrengthover60.0, whichisdetectedfrombothupstreamand
downstreamdirections.If thesignalstrengthdetectedistoo low,thetransducerinstallationpositionand the

4.2.2. Signal Quality(Qvalue)
QvalueisshortforSignalQuality(displayedinmenu 90).Itindicatesthelevelofthesignaldetected.Qvalueis
indicatedbynumbersfrom00~99. 00 representstheminimumsignaldetectedwhile99 representthemaximum.
Thetransducerpositionmaybeadjustedandenough couplingusedtogetthesignalqualitydetectedasstrongas
possible.
4.2.3. TotalTimeandDeltaTime
TotalTimeand DeltaTime”aredisplayedinmenu93. Themeasurementcalculationsintheflowmeterarebased
upon thesetwoparameters.Therefore,when DeltaTime”fluctuateswidely,theflowand velocitiesfluctuate
accordingly.Thismeansthatthesignalqualitydetectedistoopoor. Itmaybetheresultedofpoorpipe-installation
conditions, inadequatetransducerinstallationorincorrectparameterinput.
Generally, DeltaTime”fluctuationshouldbeless than±20%.Onlywhenthepipediameteristoosmall or

4.2.4. TransitTimeRatio
Transit TimeRatioindicatesifthetransducermountingspacingisaccurate.Thenormaltransit timeratioshould
be100±3 iftheinstallationisproper. Checkit menu91.
ATTENTION
If thetransit timeratioisover100±3, it isnecessarytocheck:
(1) If theparameters(pipeoutsidediameter,wall thickness,pipematerial,liner,etc.)have
beenenteredcorrectly,
(2) If thetransducermountingspacingisaccordancewiththedisplayinmenu25,
(3) If thetransducerismountedatthepipe’scenterlineonthesamediameter,
(4) If thescaleistoothickorthepipemountingisdistortedin shape, etc.
Warnings

(1) Duringtheinstallation,applyenoughcouplingcompoundtostickthetransducerontothepipewall.
WhilecheckingthesignalstrengthandQvalue,movethetransducerslowlyaroundthemountingsite
