User’sResponsibilityforSafety:OMEGAENGINEERINGmanufacturesabroadrangeoflevelsensing
technologies.Whileeachofthesesensorsisdesignedtooperateinawidevarietyofapplications,itisthe
user’sresponsibilitytoselectasensormodelthatisappropriatefortheapplication,installitproperly,perform
testsoftheinstalledsystem,andmaintainallcomponents.Thefailuretodosocouldresultinproperty
damageorseriousinjury.
ProperInstallationandHandling:Onlyprofessionalstaffshouldinstalland/orrepairthisproduct.Installthe
switchwiththeincludedFKMgasketandneverovertightentheswitchwithinthefitting.Alwayscheckfor
leakspriortosystemstart‐up.
WiringandElectrical:Asupplyvoltageof12to28VDCisusedtopowertheLVU800Series.Electricalwiring
ofthetransmittershouldbeperformedinaccordancewithallapplicablenational,state,andlocalcodes.
MaterialCompatibility:TheenclosureismadeofPolycarbonate(PC).Thetransducerismadeof
PolyvinylideneFluoride(PVDF).Makesurethatthemodel,whichyouhaveselected,ischemicallycompatible
withtheapplicationmedia.
Enclosure:Whiletheswitchhousingisliquid‐resistanttheLVU800Seriesisnotdesignedtobeoperational
whenimmersed.Itshouldbemountedinsuchawaythattheenclosureandtransducerdonotcomeinto
contactwiththeapplicationmediaundernormaloperationalconditions.
Theenclosurehasaflipcoverwithdual1/2”NPTfemaleconduitportsandaninternalterminalstripfor
wiring.Toopentheenclosure,youwillneedasmallinsertiontoolsuchasascrewdriver.Loosenthelocking
screwlocatedatthetopfrontoftheenclosure.Rotatethehingedcoverupfor135°accesstothefaceplate
andterminalstrips.Beforeclosingtheenclosure,makesurethattheenclosuregasketisproperlyseated,and
thatanyconduitfittings,cableconnectorsorplugsareinstalledcorrectlyandsealed.
HandlingStatic‐SensitiveCircuits/Devices:Whenhandlingthetransmitter,thetechnicianshouldfollowthese
guidelinestoreduceanypossibleelectrostaticchargebuild‐uponthetechnician’sbodyandtheelectronic
part.
1. Alwaystouchaknowngoodgroundsourcebeforehandlingthepart.Thisshouldberepeatedwhile
handlingthepartandmorefrequentlyaftersittingdownfromastandingposition,slidingacrossthe
seatorwalkingadistance.
2. Avoidtouchingelectricalterminalsofthepartunlessmakingconnections.
3. DONOTopentheunitcoveruntilitistimetocalibrate.

Generalnotesforelectricalconnections,usageandsafety:
Wherepersonalsafetyorsignificantpropertydamagecanoccurduetoaspill,theinstallationmust
havearedundantbackupsafetysysteminstalled.
Wiringshouldalwaysbecompletedbyalicensedelectrician.
Supplyvoltageshouldneverexceed28VDC.
Thesensormaterialsmustbechemicallycompatiblewiththeliquidstobemeasured.
Designafail‐safesystemforpossiblesensorand/orpowerfailure.
NeverusethesensorinenvironmentsclassifiedasHazardous.
TestingtheTransmitter

1. Connectamultimeterinserieswiththeblackwiretoreadthecurrentoutput.
2. Verifythatthecurrentincreases(tankfilling)anddecreases(tankemptying)appropriatelyinthe
calibratedspan.
3. Ifnot,carefullyobserveandattempttocorrelateanyinstallation,levelorapplicationeventformore
specifictroubleshootingdirection.
VoltageOutput
LVU800Seriescanbeusedasa0to5or0to10VDCoutputdevice.Aresistorwillneedtobeaddedtothe
circuittoenableavoltageoutput(refertothewiringdiagrambelow).

TheLVU800Seriesshouldalwaysbemountedperpendiculartotheliquidsurfaceandinstalledusingthe
providedFKMmountinggasket.Makesurethatthefittingandtransmitterthreadsarenotdamagedorworn.

b. ForLVU816,LVU826&LVU832Series‐mountatleast3”fromthesidewall
4. Donotmountwhereobstacleswillintrudeonsensor’sbeamwidth
a. SeeSpecificationsonpage4
5. Donotmountinavacuum
6. Avoidmountinginthecenterofadometoptank.
7. Inconebottomtank,positionthesensoroverthedeepestpartofthetank.

Installationinexistingfittings
IftheexistingfittingislargerthanthethreadsoftheLVU800Series,selectareducerbushingsuchasa2”

MetalTanks(LVU809seriesonly)
OmegaEngineeringultrasonictransmittershavebeenoptimizedforuseinnon‐metallicfittings.
1. Forbestperformance,avoidtheuseofmetallicfittings.
a. Useaplastic2”x1”reducerbushing(suchasLVU800‐2N80),oraplastic1”tankadapter(such
asLVU800‐1B).
2. Whileinstallationsdirectlyintoa1”metalfittingarenotrecommended,acceptableresultsmaybe
obtainedifthe1”fittingisahalfcouplinginformandtheouterdiameterofthecouplingistightly
