TheLD30serieswillbeinstallednearthebottomofthevessel.Theswitchcanbeinstalledthroughtheside
wallorthroughthebottom.Pleasenotethatthephysicallocationoftheleveltransmitterwillindicatethe
lowestlevelofmeasurementwithinthetank.Forexample:mountingthetransmitter1footfromthebottom
ofthetank,thenthelowestreadingofliquidwillbe1footfromthebottom.

Note:WheninstallingtheLD30series,designaninstallationmethodwheretheunitcanberemovedwithout
havingtoremovethefluidfromthevessel.Theuseofvalvesbetweenthetransmitterandthevesselcanallow

HowtoconvertPressureintoLiquidHeight?
PressuretransmittersarealldefinedbythepressurerangeandnotbyLiquidHeight.Toconvertpressureto
LiquidHeight,usethefollowingratio:
1psi=2.31feetofwater
or
1psi=0.704metersofwater
Therefore,a15psitransmitterwillhaveaLiquidHeight=
34.65feet(10.56m):
15psix2.31’/psi=34.65’
or
15psix0.704m/psi=10.56m
Withtheaboveratio,youcanalwaysfindtheLiquidHeightor

HowdoesSpecificGravityaffectpressuretransmitters?
TheSpecificGravity(SG)ofaliquidwillnotchangethepressureofthetransmitter,butwillaffecthowthe
transmitterreadstheliquidheight.Remember,liquidswithaSQ<1.0arelighterthanwaterandliquidswith
aSG>1.0areheavierthanwater.
WaterhasaSG=1.0.
ASG<1.0requiresmoreliquid(atallerwatercolumn)toequalthesamepressureaswithwater.
ASG>1.0requireslessliquid(shorterwatercolumn)toequalthesamepressureaswithwater.

SG=0.9

SG=1.0

SG=1.2
TocalculatetheMaximumLiquidHeightofasensor,usethefollowingformula:
MaximumLiquidHeight(feet)=(PressureRangex2.31)/SG
MaximumLiquidHeight(meters)=(PressureRangex0.704)/SG
Example:15psitransmitterinstalledinaliquidwithaSG=0.9willhavea
MaximumLiquidHeight=38.5feet(11.73m)or[(15psix2.31’/psi)/0.9=38.5’].
Note:TheaboveformulawillalwaysprovidetheMaximumLiquidHeightforanypressuretransmitter.
Example:ComparetheMaximumLiquidHeightofaliquidwithaSG=0.9toonewithaSG=1.0.
SG=0.9:a15psitransmitterwillhaveaMaximumLiquidHeight=38.5’(11.73m)
SG=1.0:a15psitransmitterwillhaveaMaximumLiquidHeight=34.65’(10.56m)
AchangeinSGof0.1willincreasetheMaximumLiquidHeightofatransmitterby3.83’(1.2m).Thus,when
theSpecificGravityislessthan1.0,theMaximumLiquidHeightofthetransmitterwillincrease.
ThereverseistruebyincreasingtheSpecificGravity.WithaSG=1.2,theMaximumLiquidHeight=28.88’
(8.80m)witha15psitransmitter.
MaximumLiquidHeight(28.88’)=(PressureRange(15psi)x2.31)/SG(1.2)
ComparetoaliquidwithaSG=1.0,theMaximumLiquidHeightwilldecreaseby5.77’(1.8m).Whenthe
SpecificGravityisgreaterthan1.0,theMaximumLiquidHeightofthetransmitterwilldecrease.
Note:Identifyingthecorrectspecificgravityforthefluidiscriticalinunderstandingtheoperationalrangeof
thepressuretransmitter.

Howtoselectthecorrectpressuretransmitter?
Theobjectiveistoselectasensorwithanoperationalrangethatwillcovertheentireapplicationspan.Ifthe
liquidheightofthetankisabovethesensor’sMaximumLiquidHeight,thenthesensorwillnotbeableto
readafulltanklevel.Comparethetank’sPressure@Fullagainstthesensor’spressurerangetoselecta
sensor.
Tocalculatethetank’sPressure@Full,usethefollowingformula:
Pressure@Full=[Height@FullTank(feet)xSG]/2.31(feet/psi)
Pressure@Full=[Height@FullTank(meters)xSG]/0.704(m/psi)
Toselectthecorrectpressuretransmitter,followthestepsbelow:
1. MeasuretheHeight@FullTank(infeetormeters).
2. DeterminetheSGfortheliquid(ifthecustomerdoesnotknow,checktheMSDSsheet).
3. UsetheformulaabovetocalculatethePressure@Full.
a. Example:A16’tankwithaliquidmediaSGof0.9hasaPressure@Fullof6.23psi.
b. [(16’x0.9)/2.31’/psi]=6.23psi
4. SelectapressuretransmitterwithapressuregreaterthanorequaltothePressure@Full.
a. Intheexampleabovefora16’talltankwithaSG=0.9,youneedapressurerangegreaterthan
orequalto6.23psi.
b. Usingasensorwithapressurerangeof15psiprovidesaMaximumLiquidHeightof38.5’,
whichwillreadtheentirerangeofthe16’talltank.
c. Usingasensorwithapressurerangeof5psiprovidesaMaximumLiquidHeightof12.83’,
whichisshortby3.17’.
i. Thismeansthatthesensorwilloutput20mAat12.83’ofliquidandthetop3.17’of
liquidwillnotbemeasured.

Howtoconfigureapanelmeterwhenapressuretransmitterisused?
ThismethodworkswiththeLI55series,LI25Series,LI10SeriesandLI50Series.Thesepanelmetersare
configuredusingtheSCALEfunction.TheSCALEfunctiontypicallyhasfoursettings.Thesesettingsareas
follows:
SettingsDefaultRepresentsTypicalSetting

Input220.000Inputcurrent@Full20.000
Display2(Full)20.000Displayvalue@FullFullValue(mA)
Remember,pressuretransmittersareconfiguredso0psi=4mAandthemaximumpsi=20mA.Most
pressuretransmitterapplicationswillnotusethefullrangeofthetransmitterandrequiresyouto
proportionallyscalethecurrentoutputofthepressuretransmitter.Therefore,afulltankwilltypicallyhavea
currentlessthan20mA.Thegoalinconfiguringthepanelmeteristocalculatethecurrentwhenthetankis
full.Todothis,usethefollowingformula:
(FullTankHeight/MaximumLiquidHeight)x16+4=CurrentatFull
Example:A16foottankwithaSG=0.9willhaveamaximumpressureof6.23psi.A15psisensorisselected
foruse.TheMaximumLiquidHeight=(15psix2.31’/psi)/0.9=38.5feet.Usingtheaboveformula,the
CurrentatFull=[(40feet/51.33feet)x16+4]=10.649mA.
TheCurrentatFullwillbeusedastheInput2value.Thismeansthatwhenthedisplayreadsacurrentequal
toCurrentatFull,itwilldisplaytheFullvalue(Display2value).Thepanelmeterwillbeconfiguredasfollows:
SettingsConfigured
Input104.000
Display1Empty
Input210.649
Display2Full
Note:ThevaluesforemptyandfullrepresentwhatthedisplaywillshowwhenthetankiseitherEmptyorFull.
EmptyandFullmustbethesameunits(example:Gallons,Inches,percent).
ThedefaultfortheInput1is4mAandtypicallywillneverbechanged.
