InstallationTip
1. Floatleveltransmittershouldbeinstalledrigidlysothefloatisfreetomoveastheliquidlevelchanges.
2. Floatleveltransmittershouldbemountedinatankareafreeofsevereturbulenceorprotectedfrom
suchturbulencebyappropriateandadequatesloshshields.
3. Floatleveltransmitter’sstemsshouldbeverticalforbestresults,butsatisfactoryoperationispossible
inmostliquidswiththestematuptoa30°anglefromvertical.
4. CareshouldbetakenthatFloatleveltransmitterisalwaysoperatedwithinelectricalratings.
ThreadTreatment(Sealing)
When threading metal threads into a metal coupling, pipe sealant or Teflon tape is recommended.  When
threading a metal sensor into a metal coupling, the installer should use a suitable wrench and tighten the
threads1/2turnpasthandtight.
MaterialCompatibility
o TheLV55seriesismadeof316StainlessSteel(316SS)withatophousingmadeofPolypropylene(PP).
o Make sure that the switch is compatible with the application liquids.  To determine the chemical
compatibilitybetweenthesensoranditsapplicationliquids,refertoachemicalcompatibilityguideor
consultachemist.

MAINTENANCE StepSix
Maintenanceshouldconsistofinspectiontoseethatthefloatis free to move and not coated with any
substance,whichwouldchangeitsweightorvolumesignificantly.Ifthisoccurs,thefloatshouldbecleaned.
Thisiseasilyaccomplishedwithoutdisturbingtheinstallation.Inaddition,thestemmaybewipeddownto
removeanybuild‐up.Theonlyrepairpossibleinthefieldisreplacementofeitherthefloatorstem.Dentsor
nicksonthefloatareusuallyofnoconsequencetooperation.
Cautions
FLOWLINE, Inc. manufactures a wide range of liquid level switchesandtechnologies.Whileeachofthese
switchesaredesignedtooperateinawidevarietyofapplications, it is the user's responsibility to selecta
switch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.
1. Thepressure,temperatureandelectricallimitationsshownforthespecifiedlevelsensormustnotbe
exceeded.
2. Thepressuresandtemperaturesmusttakeintoconsiderationpossiblesurgesinthetemperatureand
pressureofthesystem.
3. Theliquidsusedmustbecompatiblewiththematerialsofconstruction.
4. Life expectancy of the sensor varies with applications.  Contact the factory if life cycle testing is
required.
5. Ambienttemperaturechangescanaffectsensorsetpoints,sincespecificgravitiesofliquidsvarywith
temperature.Consultfactoryforassistance.
6. Levelsensorshavebeendesignedtobeshockandvibrationresistant.Formaximumlife,bothshould
beminimized.Consultfactoryforassistance.
7. Excessive contaminants in fluid may inhibit float operation andoccasionalwipedownmaybe
necessary.
8. Physicaldamagetoproductmayrenderproductunserviceable.
9. Installationinavesselmadefrommagneticmaterialsmayaffectoperation.
Cleaningprocedure
1. Power:Makesurethatallpowertothesensor,controllerand/orpower supply is completely
disconnected.
2. Sensor removal:Ifnecessary,makesurethatthetankisdrainedwellbelowthe switch prior to
removal.Carefully,removethetransmitterfromtheinstallation.
3. Cleaningthesensor:Usingasoftbristlebrushandmilddeter‐gent,carefullywashtheswitch.Donot
useharshabrasivessuchassteelwoolorsandpaper,whichmightdamagethesurfaceofthesensor.
Donotuseincompatiblesolvents,whichmaydamagethesensor's316SSbody.Takeparticularcareto
removeanyscalingfromthefloatbodyandmakesurethatitmovesfreely.
4. Sensorinstallation:FollowtheappropriatestepsofinstallationasoutlinedintheInstallationsection
ofthismanual.
