OperatingPrinciple
Thesensoremitsamicrowavepulsefromitsantenna,whichtravelsatthespeedoflighttothesurfaceofthemedium
below.Aportionofthatenergyreflectsoffthemediumandreturnstotheantenna.Thetimegapbetweenenergy
emissionandreceiptiscalledthe“timeofflight”,andisproportionaltothedistancebetweenthemediumsurfaceand
thesensorsmeasurementlocation,whichistypicallylocatedatthebottomoftheantenna.Thesensormeasuresthe
timeofflightandtranslatesthisvalueintoacontinuous4‐20mAsignaloutputthat’sproportionatetolevelwithina

INSTALLSENSORSectionThree
InstallationRequirements
EchoPulse™measuresthedistancebetweenthesensorandtheliquidsurfacebelow.Typically,allmeasurementsfrom
thesensororiginatefromthebottomoftheantenna.RefertotheMeasurementReferenceCharttodeterminethe
locationwheremeasurementoriginatesonyoursensor.Toensurereliablemeasurement,adheretothefollowing
minimuminstallationrequirements:
1. Therearenoobstructionsbetweenthebottomedgeoftheinstalledantennaandthesurfaceoftheliquidbelow
includingladders,walls,tankseams,liquidinflows,rails,othersensors,mixerblades,heatingcoils,pumps,struts
orapparatus.Note:Additionally,whenthesensortransmitsamicrowavepulse,theRFsignalspreadsinaconical
shape(determinedbyitsbeamangle)overdistance.RefertotheBeamAngleCharttodetermine,whatifany,
additionalmeasurementspaceisrequiredtobefreeofsuchobstacles.Ifsuchitemsarepresent,thenaFalse
EchoCurveconfigurationmustbedone(SectionSeven).
2. Thesensormustbeinstalledwiththeantennaperpendiculartothesurfaceoftheliquid.
3. Thesensormustbeinstalledwithadistance≥19.7”(500mm)fromthesidewallofthetank.
4. Theliquidlevelmustnotbeallowedtoenterintothedeadband(blankingzone)ofthesensor.
5. Thesensorinstallationmustbedoneinaccordancewithrelevantlocalorfederalsafetyregulations.
6. Thesensormustbeconnectedtoelectricalground.
7. Donotusethehousingtoscrewthesensorintotheinstallationfitting(LR10&LR15Series).
1. Applyingatighteningforceagainstthehousingmaydamagethesensor.
8. Makesurethatallpartsofthesensorexposedtotheapplication,specificallyanyportioninstalledwithinthe
tank,aresuitablefortheprocess.
1. Consideranyeffectsfromtheapplicationtemperature,pressureormedia.
FCCConformity

Changesormodificationsnotexpresslyapprovedbythemanufacturercouldvoidtheuser’sauthoritytooperate
theequipment.
Warning:Usermustkeepasafetydistanceofatleast20cmfromtheantenna.
Note:LR10,LR15(2”horn)seriesThisequipmenthasbeentestedandfoundtocomplywiththelimitsfora

totrytocorrecttheinterferencebyoneormoreofthefollowingmeasures:
Reorientorrelocatethereceivingantenna.
Increasetheseparationbetweentheequipmentandthereceiver.
