Warning
Maycause injury.
Attention
Maydamage the flowmeter.
Some ofthe instructionsmaybe differentfromthe flowmeterand analyzeryou havepurchased. Thatdependson
the configuration requirements. It also maybe due to changesin productdesign, modification and upgrade .You
will find the flowmeterdisplayinterface intuitive and easyto understand and it shall prevail when there isno

2.3 MeasurementSiteSelection
Compared with otherkindsofflowmeters, Ultrasonic Flowmeteristhe simplestone to install. Choose a proper
measurementsite, enterthe pipe sparameters into the flowmeter.Install and fix the transducers on the pipe as
instructed bythe meterand start the measurement.
When selecting ameasurementsite, it isimportantto selectan area where thefluid flowprofile isfullydeveloped
to guarantee a highlyaccurate measurement. Use the following guidelinesto selecta properinstallation site:
lChoosea section ofpipe thatisalwaysfullofliquid, such asa verticalpipe with flowin the upwarddirection
ora full horizontalpipe.
lEnsure enough straightpipe length atleastequalto the figure shown belowforthe upstreamand downstream
transducers installation.
lOn the horizontalpipe, thetransducershould be mounted on the 3 o clock and 9 o clock position ofthe pipe
section, avoid the 6 o clock and 12 o clock position, in orderto avoid the signalattenuation caused bythe
sedimentatthe bottom, orair bubblesorcavitation.
lEnsure thatthe pipe surface temperature atthe measuring pointiswithin the transducertemperature limits.
lConsiderthe inside condition ofthe pipe carefully.Ifpossible, selecta section ofpipewhere the inside is
free ofexcessive corrosion orscaling.
lChoosea section ofsound conducting pipe.

3TransducerInstallation
3.1 InstallingtheTransducer
Before installing the transducers, clean the pipe surface where the transducers are to be mounted. Remove anyrust,
scale orloose paintand make a smooth surface. Choose asection ofsound conductingpipe forinstalling the
transducers.Applya wide band ofsonic coupling compound down thecenterofthe face ofeach transduceras
well ason the pipe surface, ensure there are no air bubblesbetween the transducers and the pipe wall, and then
attach the transducers to the pipe with the strapsprovided and tighten themsecurely.
Note:
1. The two transducers shouldbe mounted atthe pipe scenterline on horizontalpipes.Make sure thatthe
transducermounting direction isparallelwith the flow.
2. During the installation, thereshould be no air bubblesorparticlesbetween the transducerand the pipe wall.
On horizontalpipes, the transducers shouldbe mounted in the 3 o clock and 9 o clockpositionsofthe pipe
section in orderto avoid anyair bubblesinside the top portion ofthe pipe.
3. Referto 2.15 forthe TransducerMounting Spacing.
4. Ifthe transducers cannotbe mounted horizontallysymmetricallydue to limitation ofthe localinstallation
conditions, it maybe necessarytomountthe transducers ata location where there isa guaranteed full pipe
condition (the pipe isalwaysfull ofliquid).
3.1.1 TransducerMountingMethods
Three transducermounting methodsare available. Theyare respectively:Vmethod, Zmethod and Nmethod.
The Vmethod isprimarilyused on small diameterpipes(DN100~300mm, 4"~12"). The Zmethod isused in
applicationswhere the Vmethod cannotwork due topoorsignalorno signaldetected. In addition, the Zmethod
generallyworksbetteron largerdiameterpipes(overDN300mm, 12")orcastiron pipes.
The Nmethod isan uncommonlyused method. Itisused on smallerdiameterpipes(belowDN50mm, 2").
3.1.2 VMethod
The Vmethod isconsidered asthe standard method. Itusuallygivesa more accurate reading and isused on pipe
diameters ranging from25mmto 400mm(1"~16")approximately. Also, it isconvenientto use, butstill requires
properinstallation ofthe transducers, contacton the pipe atthe pipe scenterline and equalspacing on eitherside
ofthe centerline.
3.1.3 ZMethod
The signaltransmitted in a Zmethod installation hasless attenuation than a signaltransmitted with the V
method
when the pipesaretoo large,there are some suspended solid in the fluid, orthe scalingand linerare too thick .
Thisisbecausethe Zmethod utilizesa directlytransmitted (ratherthan reflected)signalwhich transversesthe
liquid onlyonce. TheZmethod isable to measure on pipediameters ranging from100mmto 5000mm(4"to
200")approximately. Therefore, we recommend the Zmethod forpipe diameters over300mm (12").

3.1.4 NMethod (notcommonlyused)
With the Nmethod, the sound wavestraverse the fluid three timesand bounce twice offthe pipe walls. Itis
suitable forsmallpipe diametermeasurement. The measurementaccuracycan be improved byextending the
transit distance with the Nmethod (uncommonlyused ).
3.2 TransducerInstallation andFixing
Transducers can be installed onto the pipe with itsmagnetic racks. Ifyou need to fasten them, then you can use
the chainsto make it firm. Showasbelow:
3.3 TransducerMounting Inspection
Confirmthe transducerisinstalled properlybychecking the detected signalstrength,totaltransit time, delta time
aswell astransit time ratio Key9.
The "mounting"condition directlyinfluencesthe flowvalue accuracyand systemlong-termoperation reliability.
Inmostinstancesit isonlynecessaryapplya wide band ofsonic coupling compound lengthwise on the faceofthe
transducerand stick it to the outside pipe wall to getgood measurementresults. However, the following checks
still need to be carried outinorderto ensure ahigh reliabilityofthe measurementand long-termoperation ofthe
instrument.
