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®
Manualorothersupportdocumentationlocatedatwww.flowline.com.
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.

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
position.
TOP‐LEVELMENU
Thesensorisconfiguredwiththethreebuttonsonthesensorface
(UP,DOWNandSELECT)andthesensor’sLCD.Toaccessthe
sensor’sTop‐levelmenu,simplyholddowntheSELECTbuttonfor
fiveseconds.Thedisplaymenuwillautomaticallybegintoscroll
throughtheTOP‐LEVELMENU.
Whenthemenuscrollstoanitemyouwishtoconfigure,simply
presstheSELECTbuttontochoosethatitem.TheTOP‐LEVEL
MENUwillcontinuetoscrollthroughthefollowing(UNITS–TANK–RELAY1–RELAY2–
RELAY3–SAFE–(MPLEX)‐HELP–RUN),soifyoumissyourselection,itwillappearagain
shortly.
ToreturntotheTOP‐LEVELMENU,pressSELECTwhenEXITappears.
ToreturntoOperationalModeofthesensor,pressSELECTwhenRUNappearsinthe
TOP‐LEVELMENU.
Note:Tospeedupthescrollingofthevaluesonthedisplay,holddowntheSELECT
buttonwhileholdingdowntheUPorDOWNbuttons.
