SAFETYPRECAUTIONS StepThree
AboutThisManual:PLEASE READTHE ENTIREMANUAL PRIORTO INSTALLINGORUSINGTHISPRODUCT.
Thismanual includesinformation ontheLevelTrackKitinstallationfitting fromOmegaEngineering:LVM‐
11, LVM‐12, LVM‐13, LVM‐14 &LVM‐15 Series.Please refer to the part number located on the labelto
verify the exact model which you have purchased.Many aspects of installation and use are similar
betweenmodels.
User’s Responsibility for Safety:OMEGA ENGINEERING manufactures several models of liquid level
sensors, controller and mounting systems.It is the user’s responsibility to select components that are
appropriatefortheapplication,installitproperly,performtestsoftheinstalledsystem,andmaintainall
components.Thefailuretodosocouldresultinpropertydamageorseriousinjury.
Proper Installation and Handling:Use a proper sealant with all installations.Never over tighten the
components.Alwayscheckforleakspriortosystemstart‐up.
MaterialCompatibility:Thetrack,endcap,wire retainerclips,bayonetadapterandsensorcarforall the
LVM‐11/‐12/‐13/‐14/‐15modelsare made of glassfilledPP(Polypropylene, a polyolefin).The sensor car
locking bolt and screw are made of PCTFE (polychlorotrifluoroethylene, a fluoroplastic), the top
compressionfitting,thrust plate, lockingpinand2" NPT fittingaremadeof PP andtheO‐ring is madeof
Viton (a fluorocarbon).The wire gasket is made of Neoprene, the seal plug is madeof Santoprene and
both have a silicon gel for lubrication.Make sure that the application liquids are compatible with the
materialsthatwill be wetted.To determinethechemicalcompatibility between thecomponentsandits
applicationliquids,refertotheCompassCorrosionGuide,availablefromCompassPublications.
Temperature and Pressure:Level Track Kit is designed for use in application temperatures up to 80° C
(176°F).Itisnotdesignedforpressurizedapplicationsduetothewiringthatmusttravelthroughagasket
atthehead.
Wiring and Electrical:Electrical wiring of any liquid level control system should be performed in
accordance with all applicable national, state, and local codes.Take care not to cut or break the outer
insulationjacket ofwiringthat maybeimmersedwhileroutingcablesintheLevel TrackKitsystem.Such
breaksoftheliquidsealofthesensorsystemmayleadtocomponentfailure.
Flammable or Explosive Applications: Level Track Kit may be used within flammable or explosive
applications only if the associated components are rated intrinsically safe for such use.In hazardous
applications,useredundantmeasurementandcontrolpoints,eachhavingadifferentsensingtechnology.

Sensorcarandbayonetadapter:Thesensor car kit is the heart of the Level Track Mounting Kit system.It
slidesinthegroovesofthetrack,andislockedintopositionbyaplasticboltandscrew.Thebayonetto3/4"
NPT adapter has a female 3/4" NPT fitting on one end where the sensor (not included) will screw in, and a
bayonet fitting on the other end that attaches it onto the sensor car with a slight turn, with an O‐ring in‐
betweentoprovidetensionforthepush‐and‐turnconnection.

b. Screw the bayonet adapter onto the sensor until the cap of the sensor seats against the pit
insidetheadapter.
c. Thread the blackO‐ringonto thesensorwire and pushitinto the bayonetsideof the bayonet
adapter,seatingitfirmlyintotheadapter.
d. Thread thesensor wire into the sensor car and out throughthe hole between the sensor car

compatibility.Thismakes itstiffer thanconventionalwire.Takecarenottobend thewire toosharply to
the point where the insulation is broken.Such a break could cause liquid to enter the wiring, damaging
thesensor.

Procedurefortwoormoresensors:Ifmorethanonesensorwillbeinstalledonthetrack,repeatthe
proceduresabovefor each sensor.However,donot mountthesensorstoo closely togetherbecause
twosensors ondifferentside ofthetrackcannotfit througha2” NPTfittingatthetop ofthetank.If
adjacent mounting is necessary you may need to install the other sensor in temporary staggered
positions,slidingtheminto the correctpositionafter the Level TrackKitsystem has beenmountedin

3. Connectthetracktothetopfitting:
a. Thread the sensor wire(s) through the bottom of the 2” NPT to the Level Track Kit system

SelectingaLocation:TheLevel TrackKitshouldbemountedverticallyatapointinthetankwhereitwillnot
be exposed to excessive stress (such as radial mixing velocities in excess of 1.5 feet per second).When
mounting in a tank with a mixer, mount the LVM‐11/‐12/‐13/‐14/‐15 series close to the tank wall were
velocitiesarelowest.Choose a mountinglocationwherethe sensorswillfunctioncorrectly (awayfrominlet

It is the user’s responsibility to identify the proper placement and method of installation for the specific
application.

Ifdamaged,useanewadapter.
2. Insertthe assembledLevelTrack Kitsystem throughthetank adapter.If
several sensors are too close together to fit through the tank adapter,
slide them to a different locations so that only one sensor is going
throughtheadapteratatime.
3. To ensure a proper seal, apply an appropriate sealant to the threads of
the Level Track Kit system.Screw the LVM‐11/‐12/‐13/‐14/‐15 series

1. Install the side mount bracket (LVM‐30 series) at the desired location.
Make sure the threads of the bracket are not damaged or worn.If
damaged,useanewbracket.
