WelcometotheEchoSwitch®QuickStart

TheEchoSwitch®QuickStartprovidesbasicmounting,setupanduseinstructionsfor

gettingtheEchoSwitch®upandrunningquickly.Ifyouhaveanon‐standardinstallation

orsetuprequirementthatisnotaddressedhere,pleaserefertotheEchoSwitch®

WeDoYourLevelBest

ThankyouforpurchasingEchoSwitch®.ThesensorprovidesintegratedLCDandthree

push‐buttonconfiguration.Thisquickstartincludeseverythingyou’llneedtogetthe

sensorupandrunning.

Components

Dependingonhowthesensormodelthatwasshipped,EchoSwitch®comeswithaViton®

MountingtheEchoSwitch®

Thesensorshouldalwaysbemountedperpendiculartotheliquidsurfaceusingtheprovided

Viton®mountinggasket.Makesurethattherearenorestrictionsorobstaclesinthepathof

theacousticsignal.Forfurthermountinginformation,pleaserefertotheEchoPod®manual

andinstructionvideolocatedatwww.flowline.com.

EchoSwitch®has1”NPTorGthreadsandrequirescareinfittingselectionandmountingtoreduce

anycouplingoftheultrasonicsignaltothemountingstructure.Thebelowfittingsare

recommended.

Installationinexisting2”fittings:

1) UseaLM52‐14002”threadx1”threadadapteroraLM52‐

14102”slipx1”threadadapter.Adapterswithanairgap

aroundthe1inchthreadsarerecommended.

Installationinplastictanks(useoneofthefollowing):

1) Usea1”bulkheadfitting,suchastheLM52‐1890bulkhead

fitting.

2) Usealargerbulkheadfitting,suchastheLM52‐2890witha

reducerbushingsuchastheLM52‐1400.

3) Weldaplastic1”halfcouplingtothetanktop.

Installationinmetaltanks(useoneofthefollowing):

1) UsetheLM52‐1890bulkheadfittings.

2) Useaflangewitha1”riser,suchastheLM52‐1850(where

thethreadisabovetheplaneoftheflange).Donotusea

blindflangewithatapped1”thread.

3) Usealargerflangewitha2”threadandaddareducer

bushingsuchastheLM52‐1400.

Note:Whileinstallationsdirectlyintoa1”metalfittingarenot

recommended,acceptableresultsmaybeobtainedifthe1”

fittingisahalfcouplinginformandtheouterdiameterofthe

coupleristightlywrappedwithvinyltape.

Installationinopentanksandsumps:

1)UseFlowline'sLM50‐1001‐1sidemountbracket.

LM50‐1001

IMPORTANTMOUNTINGGUIDELINES:

1) Nevermountthesensoratanangle.

2) Liquidshouldneverenterthedeadband.

3) Mountatleast3”fromthesidewall.

4) Nevermountinavacuum.

5) Donotobstructthesensor’sbeamwidth.

MountingwithaStand‐Pipe:

Astand‐pipemaybeusedtodampenturbulence,separatesurfacefoamfromthepointof

measurementorincreaseperformanceinheavyvapor.Whenmountingthesensorina

stand‐pipe,theminimumdiameterofthepipeis2”.Largerdiameterpipescanbeused.The

pipeshouldbeattachedwithacouplingortankadapterandreducerbushing.Avoidtheuse

ofmultiplepipefittingswhenpossible.Anidealmountwouldbetoselecta2”coupling(Sx

TorSxS)andconnectthepipetotheinsideslipanduseareducerbushingtoattachthe

sensor(seeexamplebelow).

Thepipelengthshouldrunthemeasurementspanandthebottomofthepipeshouldremain

submergedatalltimestopreventfoamfromenteringthepipe.Cutthebottomendofthe

pipeat45°anddrilla1/4”pressureequalizationholehighinthedeadband.Thepumps

shouldnotdriveliquidpasttheopenendofthestandpipewhichcausestheliquidinthepipe

tooscillate.

WiringtheEchoSwitch®

ThefollowingwiringdiagramcanbeusedwhenwiringtotheEchoSwitch®relays.

Note:AllthreerelayssharetheCOMterminal.Relay1hasbothaNOandNCterminal

whileRelays2and3havejustaNOterminal.

Note#1–Isolatepowertoinstrumentfrompowertoload(pumps,etc.)asmuchas

possiblebyrunningpowertothesensordirectlyfrommainpowersource.

Thefollowingwiringdiagramscanbeusedforthe4‐20mAoutputoftheEchoSwitch®.



Somenotesonsafety:

Wherepersonalsafetyorsignificantpropertydamagecanoccurduetoaspill,the

installationmusthavearedundantbackupsafetysysteminstalled.

Wiringshouldalwaysbecompletedbyalicensedelectrician.

Thesensormustbechemicallycompatiblewiththeapplication.

Designafail‐safesystemforpossiblesensorand/orpowerfailure.

Neverusethesensorinclassifiedhazardousenvironments.

ConfiguringtheSensor

EchoSwitch®canbeconfiguredbeforeinstallation.Theswitchfeaturesnon‐volatile

memory,sothesetpointsconfiguredbeforeinstallationwillnotbelostwhentheswitchis

powereddown.Tostart,allyouneedisthefollowinginformation:

BasicTankInformation

oHEIGHT–Distancefromthetransducerfaceto

thebottomofthetank.

oFILL‐H–Maximumfillheightoftheliquidfrom

thebottomofthetank.

SetPoints(Relays):

oYouwillneedthemeasureddistancefromthe

bottomofthetanktoeachsetpoint.

oPumpandValveoperationswillhavetwoset

points,oneforONandtheotherforOFF.

oThesevalueswillallbeinthesameunitof

measurement(inches,centimeters,feetor

meters)andwillallbemeasuredfromthe

bottomofthetank.

Power:

oProvideinputpowertotheEchoSwitch®.

Note:TheHeightandFillHeightsettingsalsodeterminethe4to20mAcurrentspan.The

Heightsettingdeterminesthe4mApositionandtheFill‐Hsettingdeterminesthe20mA
