INTRODUCTION/TABLEOFCONTENTS StepOne
The EchoSonic® II is a general‐purpose ultrasonic level transmitterthatprovidesalooppowered4‐20mA
output.The4‐20mAoutputcanbeusedtoprovidetheproportionallevelofliquidinanytankorvessel.The
signalcanbeconnectedtoanydevicethatacceptslooppowered4‐20mAsignals,suchasaPLC,SCADA,DCS,
display,controller,etc.

AboutthisManual:PLEASEREADTHEENTIREMANUALPRIORTOINSTALLINGORUSINGTHISPRODUCT.
This manual includes information on the EchoSonic® II series UltrasonicLeveltransmitterfromFLOWLINE.
Pleaserefertothepartnumberlocatedonthesensorlabeltoverifytheexactmodelconfiguration,whichyou
havepurchased.
User’s Responsibility for Safety:  FLOWLINE manufactures a broad range of level sensing technologies.
Whileeachofthesesensorsisdesignedtooperateinawidevariety of applications, it is the user’s
responsibilitytoselectasensormodelthatisappropriatefortheapplication,installitproperly,performtests
oftheinstalledsystem,andmaintainallcomponents.Thefailuretodosocouldresultinpropertydamageor
seriousinjury.
ProperInstallationandHandling:Onlyprofessionalstaffshouldinstalland/orrepairthisproduct.Install
the transmitter with the included Viton® gasket and never over tighten the transmitter within the fitting.
Alwayscheckforleakspriortosystemstart‐up.
Wiring and Electrical:  A supply voltage of 12 to 28 VDC is used to power the EchoSonic® II.  Electrical
wiring of the transmitter should be performed in accordance with all applicable national, state, and local
codes.
Material Compatibility:TheenclosureismadeofPolycarbonate(PC).Thetransduceris made of
PolyvinylideneFluoride(PVDF).Makesurethatthemodel,whichyouhaveselected,ischemicallycompatible
withtheapplicationmedia.
Enclosure:  While the transmitter housing is liquid‐resistant the EchoSonic®IIisnotdesignedtobe
operationalwhenimmersed.Itshouldbemountedinsuchawaythattheenclosureandtransducerdonot
comeintocontactwiththeapplicationmediaundernormaloperationalconditions.
The enclosure has a flip cover with dual 1/2” NPT female conduit ports and an internal terminal strip for
wiring. To openthe enclosure, youwillneed a smalltool suchasascrewdriver.Loosenthelockingscrew
locatedatthetopfrontoftheenclosure.Rotatethehingedcoverupfor 135°access to thefaceplate and
terminalstrips.Beforeclosingtheenclosure,makesurethattheenclosuregasketisproperlyseated,andthat
anyconduitfittings,cableconnectorsorplugsareinstalledcorrectlyandsealed.

 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.
 Supplyvoltageshouldneverexceed28VDC.
 Protectthesensorfromexcessiveelectricalspikesbyisolatingthepower,wheneverpossible.
 Thesensormaterialsmustbechemicallycompatiblewiththeliquidstobemeasured.
 Designafail‐safesystemforpossiblesensorand/orpowerfailure.
 Neverusethesensorinenvironmentsclassifiedashazardous.
VoltageOutput:EchoSonic®IIcanbeusedasa0to5or0to10VDCoutputdevice.Aresistorwillneedtobe

The EchoSonic® II should always be mounted perpendicular to the liquid surface and installed using the
provided Viton® mounting gasket.  Make sure that the fitting and transmitter threads are not damaged or
worn.Alwayshand‐tightenthetransmitterwithinthefitting.Performaninstalledleak test under normal

Installationinexistingfittings:Iftheexistingfittingislarger
than the threads of the EchoSonic® II, select a reducer
bushing such as the LM52‐1400 (2” thread x 1” thread) or
LM52‐2400(3”threadx2”thread).

MetalTanks(LU27seriesonly):TheLU27serieshasbeenoptimizedforuseinnon‐metallicfittings.
1. Forbestperformance,avoidtheuseofmetallicfittings.
a. Useaplastic2”x1”reducerbushing,suchastheLM52‐1400oraplastic1”flange,suchasthe
LM52‐1850formetallictanks.
2. 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 coupling is tightly
