1. INTRODUCTION
TheOperationManualcontainsguidelinesandruleswhichrefertoEurosensfuelflow
meters(hereinafterFlowmeter),developedbyJSCMechatronics,Vilejka,Belarus
(mechatronics.by).
TheManualisintendedforspecialistswhoarefamiliarwithautomobilerepair,mounting
andmaintenanceandpossessprofessionalknowledgeinthefieldofelectricalandelectronic
equipmentofvariousvehicles.
Forqualityinstallationandoperationitisrecommendedtotraininstallersinthe
manufacturingcompanyorinthespecializedcenters.Theinstallerandthepersonresponsiblefor
themaintenanceofflowmetersshouldknowthestructureoffuelsystemsandtheiroperating
features.
Thesourcesofdangerduringtheinstallationandoperationoftheflowsensorsare
electricalcurrentandworkingfluid,whichcanbepressurizedto2.5MPaandhavetemperature
upto85°C.
WARNING!
Themanufacturerreservestherighttochangethetechnicalcharacteristicsoftheflow
sensorswithoutcompromisingwiththeconsumer,withoutleadingtoadeteriorationintheir
consumerqualities.
Installationanddeinstallationofflowsensorsmustbecarriedoutwithcompletelyno
excesspressureinthepipeline.
2. DESCRIPTIONANDOPERATIONOFFLOWMETERS
2.1. Use
Eurosensflowmetersaredesignedtocontrolavolumeflowandthevolumeofoil
productsthatflowthroughtheflowsensor,operateinfrigidandmildclimate.Thesensorsare
installedonstationaryormobileunitsforfuelconsumptioncontrolandforautomaticflowcontrol
andregulationindifferentbranchesofindustry,agricultureandtransport.

motorfuel
biofuels
Otherliquidfuelsandmineraloilwithakinematicviscosityof1.5to6mm2/s.


WARNING!
1)Alltheflowmetersarecalibratedfordieselfuelbythemanufacturer.Ifyouorderitto
measureanothertypeoffluid,pleaseindicateitsviscosity.
2)Whenworkingwiththeliquidkinematicviscosityofwhichismorethan6mm2/s,the
upperlimitofthemeasuringrangeofflowmeterspassportwillbelower,andthepressuredrop
acrosstheflowsensor‐higher.
3)Theamountofimpuritiesintheliquidshouldbenomorethan0.1mm.
4)Flowmeterismadeofmaterialsresistanttogasoline.However,whenworkingwith
gasolineoperationlifeofflowmetermaybeshorter.Allrisksassociatedwiththesafeoperationof

4.3. Commoninstallationrecommendations
WARNING!
Thischapterprovidesthespecialcasesofengineoperationschemes.Carefullyreadthe
technicaldocumentationofthevehicleonwhichtheflowmeterisinstalled,beforemakinga
decisionofitscompatibilitywiththevehicle.
Toinstalltheflowmeteryouneed:
•aflowmeter
•ServicekitEurosensDestination
•PC
•mountingkit(soldseparately);
•Handtools(wrenches,screwdrivers).
Theflowsensorcanbemountedinanyposition:vertically,horizontallyorinclined.Do
notkinkthecableandfuelpipes(fuelsupplylines).Itisrecommendedtomountthesensor

Whensettinguponavehicleitisprohibitedtodrillthebaseframe!Ifit'simpossibleto
mountthemountingplatewithscrews,youcanusespotwelding.
Pleaseobservethefollowingrules:
1. Wheninstallingtheflowmeteronanyequipmentinordertoavoidtheentryofdirt,
rubberparticles,cordandmetalsthatareresultedfromlinecuttingandthreadscrewing,ITIS
NEEDEDtoinstalladditionalplastic(orifthepressureinsystemishigh–metallic)fuelfilters
justbeforeeverychamberandthefirststart‐uptomakewiththem.Afterhalfanhour’sworking
ofthesystemthefilterscouldbeaccuratelydismantled.
2. Ifthefuelsystemishighlycontaminated,itisneeded:
‐toperformamaintenanceworkwithreplacingtheregularfilter
‐toinstalladditionalfilters,iftherearenoregularones
3. Flangesandthreadedconnectionsmustbecleanduringconnection.
4. Wheninstalling,useonlynewcoppersealingfromthemountingkit.
5. Fuellinesmustbeprotectedfromexternaldestructiveeffects.
6. Itisnotallowedtoreducetheinternalcrosssectionofthefuellinesonthebends.
7. Fuelhosesonthevehiclemustbefixedevery0.5m.
8. Fuelhosesinlengthshouldhaveasmalllengthmargintocompensatetemperature
changes.

Fuelpumpreturnlineshouldbechangedtocirculatefuelinasmallercircle:movethe
returnlinefromtheoutputofthehighpressurepumptothefinefilterandlocktheoutputofthe
highpressurepump.
Forcorrectoperationofthemodifiedfuelsystemyouneedtomovebypassvalvefrom
fuelpumpthatmaintaintherequiredconstantpressure(1...1.5)barintheareaofthefinefuel
filterandinletofhighpressurepump.Attheoutputoftheflowsensoracheckvalve(0.15...0.5)
atmshouldbeinstalled,whichpreventsthefuelflowthroughtheflowsensorintheopposite
direction,aswellasreducestheimpactofhydrocracksinfuelsystem.
Thus,excessfuelfromsupplypumpwillgobacktothetankfromtheinletoffinefilter
andthrougheurosensDirectwillflowonlytheamountoffuelwhichisconsumedbyengine.

Advantagesofthescheme"onpressureside":
•EurosensDirectissetaftertheregularfuelfinefilter;
•Reducedflowresistanceonthesupplypumpsuctionside.
•Returnflowheatsfuelinthetank.

Disadvantagesofthescheme"onpressureside":
•coolingoffuelpumpdecreasesalittle;
•returnlinetemperatureislowerthaninthestandardfuelscheme.

WARNING!
InstallationofEurosensDirectflowmeter"onsuctionside"requiresanadditionalfuel
