SiteCalibration
WhentheCentriFlow®MeterissentfromtheFactoryitissetwithDefaultvaluesfortheStatic
CalibrationandtheCalibrationVoltage,whichwerechosenfortheparticularmaterialbeing
measuredwiththemeter.AsdescribedinthepreviousSection,theStaticCalibrationisan
adjustmentthatrangestheTransducer,theMeasurementElementofthemeter.ThisSetting
willnotchangeunlesstheElectronicFullScaleischanged.

TheCalibrationVoltage,however,istheadjustmentthatismadetoCalibrateorSiteCalibrate
theElectronicstoaparticularapplication.AlthoughtheFactorysettingmaybequiteaccurate,
itislikelyduetodifferencesininstallation,feedsystems,andmaterialbeingmeasured,that
anadjustmentbemadeaftertheCentriFlow®Meterisinstalled.Thisprocedureisverysimple
andwillrequireameansofcapturingmaterialthatisrunthroughthemeterandweighingthat
material.DependingontheConfigurationoftheCentriFlow®Meter,eitherTypeIorTypeII,
themethodofcapturingthematerialtobeweighedwillbedifferent.ForaTypeIConfigura‐
tionthematerialcanbecapturedafteritleavesthePanSectionofthemeter,ifthe
installationallows,oratsomeotherpointintheflowpathafterithasbeenmeasuredbythe
CentriFlow®Meter.ThecloserthecapturepointistotheendofthePanSectionofthemeter
thelesslikelythattherewillbelossinthemeasurementsampleandthereforelesslikelythat
therewillbeanerrorintheCalibrationoftheElectronics.Itisimportantnottocomeincon‐
tactwiththePanSectionwhencapturingthemeasurementsamplesothattheElectronics
doesnotgiveincorrectresultsfrommeasuringthecontact.Alwaysremembertofullysecure
thedoorbacktotheenclosurebeforeresumingnormalflowthroughthemeter.

WhenperformingtheSiteCalibration,itisrecommendedthataminimumoffivesamplesbe
takenbeforemakinganyAdjustmentstotheElectronics.Also,itisrecommendedthatthe
samplerunbeaminimumof10secondslong.Thiswillallowareasonableamountofmaterial
toberunthroughtheCentriFlow®MeterensuringanaccurateadjustmenttotheCalibration.
Theprocedureisexplainedasfollows:

Step1:MakesurethattheTOP.RUNpageisaccessedtobegintheprocedure.Pressthe
ResetButtonontheLowerLefttoresetyourcounttozerobeforerunningproduct
throughthemeter.

Step2:Runproductthroughthemeterforadesignatedperiodoftime,collectingthe
materialinsomemannerafterithaspassedthroughthemeter.
