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LVU2800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LVU2800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.

followtheinstructionsbelow.

1. Beforebeginning,makesurethelevelistankisattheEmpty

a. ForLVU2810Series‐mountatleast2”fromthesidewall
b. ForLVU2818,LVU2826&LVU2832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3
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.

Donotinstallat

Installationinexistingfittings
IftheexistingfittingislargerthanthethreadsoftheLVU2800Series,selectareducerbushingsuchasa2”

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,oraplastic1”flange(SeeFittingSelectiononnextpage).
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
