1. Introduction

TheOperationManualcontainsguidelinesandruleswhichrefertoEurosensDizzi
fuellevelsensors(hereinaftersensors),developedbyJSCMechatronics,Vilejka,
Belarus(mechatronics.by).
UltrasoniclevelsensorEurosensDizziisusedfornon‐contact(non‐invasive)level
measurementofacousticallytransparentliquids.
Levelmeasurementisperformedbytheexternalecholocationthroughthebot‐
tomofthetank.Youcanmeasurealsootherparametersofliquidwhensensoris
installedatsidewall.
Sensorcanhaveinterfaces:
RS‐485(LLS,MODBUSprotocol)
Analog(voltage0‐5Volts)
Frequencymodulation
Pulsewidthmodulation

3. Chooseaplacefortheinstallation
3.1. Prepare


Installationsensortankshouldbefilledwithliquidatleast2/3ofthe
volumeandhavingahorizontalposition.

3.1.1. Preparetoolsandmaterialsforinstallation.
3.1.2. Choosesensorinstallationlocationandcleanitfromdirtandrust.Itis
recommendedtoprepareseveralpossibleinstallationplaces.
3.1.3. Foroptimalsensoroperationmodeitisnecessarytoinstallitatthe
lowestpointonthecenterofthetank.
3.1.4. Insidethetank,abovethepointwherethesensorshouldbenowalls
orotherstructuralelementsofthetank.

Donotinstallthesensorintheweldandothernon‐flatnessofthetank.

3.1.5. Theworkingsurfaceofthesensorshouldbeparalleltotheliquidsur‐
face,i.e.,horizontal..

Figure1.Choosinganinstallationplace
3.1.6. ConnectsensortoPCwithahelpofUSB/RS‐485.

3.2. Testingtheinstallationplace
3.2.1. Installationplacemustbecheckedbythespecialsoftware"CAYOscil‐
loscope".Todothis,youmustfirstlubricatetheworkingsurfaceofa
homogeneousliquidwithoutairbubbles,andpressthesensortothe
installationplaceformonitoringthequalityofthesignalwaveform.


Beforeeachpressingofthesensorisnecessarytocontrolthepresence
oflubricationlayeronit!
Withoutlubricationlayersensorwillnotwork!
Thepresenceofsandgrainsorotherparticlesintheacousticcontact
zoneisunacceptable!

3.2.2. Sensorcableshouldbeorientedasitissupposedtoconnect.
3.2.3. Atthetimeofinstallation,youmustinstallafixedgaincoefficient
(otherthan"Auto")=25.
3.2.4. Slightlychangingthepositionofthesensor,toachievemaximum‐term
amplitudeofthefirstechosignal.Alsochecktheparameter
"installationquality”.


Thebestinstallationplaceforthesensorwouldbeaplacewherethere
areaseveralechoes,aswellaswheretheamplitudeofthefirstecho
signalismaximizedatthelowestgain.

4. Attachingofthesensor
4.1. Attachingbythemetaltape

4.1.1. Securealockonthemetaltapeasshownatpicturebelow.
4.1.2. Whapthetapearoundthetank,sothatitpassesthroughthecenterof
thebestlocationofthesensorinstallationandscrewthelockisina
convenientlocationfortightening.
4.1.3. Pullthetape,sufficientthatthesensordidnotfall,butyoucantake
itoutwithoutalotofeffort.

4.1.6. Prepareglueaccordingtorecipe.
4.1.7. Gentlypressthesensortotank,bubblesanddirtintheareaofinstalla‐
tionarenotallowed.
4.1.8. Bendthefreeendofthetape,topreventaccesstothelockscrewand
sealasshowninthefigurebelow.

4.1.9. Fullbygluethegapbetweenthetopofthesensorandbottomofthe
tank.
4.2. Sensormountingwithahelpofmagnets
4.2.1.Thecentersofthemagnetsshouldbealignedwiththecenterofthesensor
andequidistantfromittoevenlydistributethemechanicalload.
4.2.2.Formountingtothecylindricalsurfacemagnetandthesensorarelocated
inmannerthatlinecrossestheircenters,paralleltotheaxisofthecylindricalsur‐
face.
4.2.3.Cleantheinstallationlocationfrompaintandrust.

5. Electricconnection

ATTENTION!
1.BeforeinstallationitisnecessarytopowerOFFtheelectriccircuit
ofthevehicle.Todothis,usethebatterycircuitbreaker(ground
switch)ordisconnectthebatteryconnectors.
2.ItisrecommendedtoclampDizzicabletogetherwithstandardwir‐
ingtothevehiclechassis.
3.RememberthatcasingoftheDizzihaselectricconnectionwith
“ground”wire.Directconnectiontothevehiclebatteryatthevehicles
withbatterycircuitbreaker(groundswitch)isNOTrecommended.
Connect“ground”wireaftergroundswitch.


6. Sensorconfiguration

6.1. Measurethedistancefromthebottomofthetanktothemaximumlev‐
el.
6.2. Runtheprogram"CAY_Configuration"andmakenecessarysettings.
Please,refertotheDizziConfigurationmanual.

7. Tankcalibration

Thecalibrationoftankisneededtoreceivelevel‐>volumetableofconversion.
Thesensormeasuresthelengthdirectlyinunitsoflength,whichallowsreplace‐
mentofthesensorwithoutnewtankcalibration.Calibrationcanbeperformedin
severalways.
