Acculevel-TheAcculevelfromKellerisahighaccuracysubmersibleleveltransmier.
IncorporangallofthefeaturesoftheLevelgageincludingtheNSF61andNSF372
cercaons,theAcculevelhasaddionalfeaturesthatprovideenhancedfunconality,
includingdualoutputs;i.e.,oneanalog(4…20mA,0…5VDC,0…10VDC)andonedigital
(RS485).TheRS485interfaceprovideslevelandtemperatureinformaonandallowsthe
usertorescaletheanalogoutputfrom10…110%ofthebasicrange.Addionally,the
AcculeveliscapableofgreateraccuracythantheLevelgage,withastandardaccuracyof
0.25%BRTEBandanoponal0.1%BRTEB.TheAcculevelcanbemanufacturedin316L
stainlesssteelortaniumforincreasedresistancetocorrosion,notablyfromseawater.
Acculevel SDI -TheAcculevelSDIisaversionoftheAcculevelhighaccuracysubmersible
leveltransmierthatisavailablewithSDI-12orRS485digitalcommunicaonprotocols.
Itisavailablewithstandardaccuracyof±0.1%FSTEBinrangesupto900WCand

objects.Itisnotadvisabletoethetransmiertoapumportopiping,asanyproblem
withthetransmiercouldrequirethatthepumpbepulledfromtheinstallaon.
Someapplicaonsrequirethetransmiertobesuspendedwithoutaprotecveslling
wellorconduitaachment.Inallinstallaons,careshouldbetakentopreventdamage
tothesubmersiblecable.
Transmier Submersion -Damagetosubmersiblecablecanleadtofailureofthetrans-
mier.Kelleremploysaruggedcablejacketmaterialstominimizetheriskofcutsand
abrasion.Sll,takecarewhenloweringyourtransmierintothewell,makingsurethe
cabledoesnotdragoversharpedges.Avoiddroppingthetransmierfromthesurface.
Donotsubmergeelectricalconneconendofcable.
Condensaon protecon -Kellerhasopmizedthesizeofthecableventtominimize
theoccurrenceofwatervaporincursion.Inareasofhighhumidity,itmaybedesirable
touseaDryingTubeAssembly(desiccant)orBellowsAssemblytopreventwatervapor
fromenteringtheventtube.ContactKellerAmericafororderinginformaon.
Bending of Cable-Ourjacketedcableisquiteexible.However,caremustbetakento
ensuretheventtubeintegraltothecableisnotcrimpedwhenbendingthecabletosuit
yourinstallaon.Itisrecommendedthatthecablenotbebenttoaradiussmallerthan
1inch.
Cable Compression -Manyusersemployacompressionngtosecureourcableasit
entersajunconbox.Caremustbetakenthatthengisnotoverghtened,causing
damage to the cable and/or crimping the vent tube.

increaseswithincreasingpressure,voltagedropsacrossotherdevicesintheloop(ana-
loginputdevices,cableand/orexternalbarrierdevices)mayreducethesupplyvoltage
tothetransmierandpreventitfromprovidingthecorrectoutputaboveacertaininput

VIII. Use and Care:
Safe Handling-SafehandlingofKELLERpressuremeasurementdevicesisaccomplished
ifanominalamountofcareistaken.Thingstoavoidare:
•Sharpimpactagainsthardsurfaces
•Contactwithchemicalsknowntobecorrosivetothematerialsofconstrucon
•ProbingofpressuresensingmembranewithANYTHING
Limits of Pressure -KELLERpressuresensors,transducersandtransmiersaredesigned
towithstandacertainamountofoverpressurewithoutdamageorcalibraonshi.It
canrangefrom15Xforthelowerpressurerangesto1.1Xforthehighestranges.This
valueisdierentforeachproductandisreferredtointheproductliteratureas“Over
pressure”.Itistheuser’sresponsibilitytoensurethattheproperKELLERproductischo-
senfortheparcularpressurecondionsexpected.
Environmental condions-EachKELLERproductisdesignedtobecompablewitha
parcularenvironment.Itistheuser’sresponsibilitytoensurethattheKELLERproduct
isnotexposedtoanenvironmentalcondionforwhichitisnotdesigned.Thesecondi-
onscanincludeoperangtemperaturerangeandexposuretohigh-pressurewaterjets,
medianotcompablewiththematerialsofconstrucon,submergenceoftransmiers
notdesignedforthatpurpose,orpotenallyexplosiveatmospheres.AKELLERengi-
neercanhelptheuserdeterminethecorrectchoiceofenclosuretosuittheparcular
applicaon.
Electrical condions -EachKELLERproductisdesignedtooperateproperlywithina
specicrangeofelectricalcondions.Thespecicproductlabeldenestherang(s),
ifany,thatappliestotheproducttowhichitisaxed.Alltransmiersaredesigned
towithstandreversepolarityaswellasovervoltagetoacertainextent.Itistheuser’s
responsibilitytoensurethatallelectricalconneconsaremadetotheKELLERproducts
inaccordancewithKELLERrecommendaonsaswellaslocalelectricalcode.Wirecolors
orconnectorpin-outsareeitherprintedonthelabelaxedtotheproductorprovided

Cleaning-WARNING!Undernocircumstancesshouldthemembrane,pressureinput
port,ornosecaptotheKELLERdevicebeprobedwithanyobject.Damagetothesens-
ingmembraneispermanentand,inmostcases,requiresrepairorreplacement.
Regardingmedia-isolatedproducts,shouldthepressureinputornosecaptothesensor,
transducer,ortransmierbecomefouled,itmaybecleanedinthefollowingmanner:
Thedeviceshouldbeslowlyloweredmembrane-endintoasoluonofwarm,soapy
water.Careshouldbetakennottosubmergetheenredevice,unlessitisspecically

NOTES:
1: FOR TRANSMITTERS WITH LIGHTNING/SURGE PROTECTION,
CONNECT DRAIN WIRE TO A LOW-IMPEDANCE EARTH GROUND.
FOR TRANSMITTERS WITHOUT LIGHTNING/SURGE PROTECTION,
THIS PIN IS CONNECTED TO THE TRANSMITTER CASE.
2: DRYING TUBE ASSEMBLY - CLEAR TUBE FILLED WITH INDICATING
DESICCANT, ATTACHES DIRECTLY TO CABLE VENT TUBE,
INTERCEPTS WATER VAPOR. HIGHLY RECOMMENDED WHEN
OPERATING IS IN HIGH HUMIDITY CONDITIONS. MUST BE
PERIODICALLY RENEWED AS DESICCANT BECOMES SATURATED,
TURNING COLOR FROM BLUE (DRY) TO PINK (SATURATED).
REMOVE YELLOW CAP FROM FREE END AFTER INSTALLATION.
3: BELLOWS ASSEMBLY - ALTERNATIVE TO THE DRYING TUBE, THIS
ANEROID BELLOWS ATTACHES TO CABLE VENT TUBE AND
REQUIRES NO PERIODIC MAINTENANCE. RECOMMENDED WHERE A
SLIGHT SACRIFICE IN ACCURACY CAN BE TOLERATED.
