INSTALLATION StepOne

1. Attachthesensor(s)tothesensorcar(s):

a. Thread the sensor wire through the bayonet to the ¾”  NPT adapter, making the approach from the

threadedside.

b. Screwthebayonetadapter ontothe sensoruntil thecapof the sensor seatsagainstthe pitinsidethe

adapter.

c. Thread

theblackO‐ringontothesensorwireandpushitintothe bayonetsideofthebayonetadapter,

seatingitfirmlyintotheadapter.

d. Threadthesensorwireintothesensorcarandoutthrough the holebetweenthesensorcarshoeand

thelockingbolt.

Note:The sensor wire insulation is made from polypropylene or perfluoroalkoxy to ensure chemical

compatibility.Thismakesitstifferthanconventional wire.Takecarenottobendthewiretoosharplyto

the pointwhere theinsulation is broken.Such a  break couldcause liquid toenter thewiring, damaging

thesensor.

e. Pullthesensorwirethroughtheholewhilepushingthesensorandbayonettowardsthesensorcaruntil

the bayonet is in position.Align the slots on the bayonet with the pine on the sensor car, and firmly

pushtogether.Whenthepinisinthecorrectposition,

turnthebayonetuntilitisinthelockedposition.

2. Slidethefirstsensorcarintothetrack:

a. Placethesensorcarlockingbolt(withthesquaretaperedhead)throughtheholeontheflatsideofthe

sensorcar,andplacetheslot‐headnutthroughtheotherside.Screwthemtogetherseveralturns,but

donottightenthemallthewayyet.

b. Oneendofthetrackhasaholedrilledhorizontallythroughit.Thisisthetopofthetrack.Youwillwant

toinsertthesensorcaronthebottomendofthetrack(oppositethehole).Slidetheboltofthesensor

car into the track (make sure the bolt head is turned so that the beveled edges are aligned with the

beveled edges of the track, see illustration on previous page).Then slide the shoe (the lower end

closesttothesensor)ofthesensorcarintothetrack.

c. Slidethesensortothedesiredposition/depth.Tightenthesensorcarlockscrewwithascrewdriver.To

notovertighten.Routethewireinsidethetrack.Slidethewireclipsintothe tracktoholdthewirein

thetrack.Donotcutthewiretolengthyet.

Procedure for two or more sensors:If more than one sensor will be installed on the track, repeat the

procedures above for each sensor.However, do not mount the sensors too closely  together because two

sensors on different side of the track cannot fit through

a 2” NPT fitting at the top of the tank.If adjacent

mountingisnecessaryyoumayneedtoinstalltheothersensorintemporarystaggeredpositions,slidingthem

intothecorrectpositionaftertheLevelTrackmountingsystem(LVM‐10series)hasbeenmountedinthetank.
