An magneticflowmeter isused
for volumeflowmeasurement of
electricallyconductiveliquids.
Measurement principleisbased
on Faradaylawon
electromagneticinduction.A
sensor consistsofanon-
magnetictube with non-
conductivelining, measuring
electrodesandtwo coils
generatingelectromagnetic
field. Flowing liquidforms a
conductor.Magneticfield
inducesvoltage Uinthis
conductor thatisproportionalto
magneticinduction B,distance
betweenelectrodes dandflow
velocity v.
U =Bx d xv
Asmagneticinduction and
distance between electrodes
are constant, induced voltage is
proportionaltovelocityofliquid
flowinthe tube. Volume flow
rate isproductofflowvelocity
and tubecross section.

Principle of measurement
Technical solution
The magneticflowmeter itself
consistsoftwobasicparts–a
flow sensor andaconverter.
The converter can beeither an
integralpart ofthe sensor
(compactversion) or separated,
connectedwiththesensor
using a cable (remote version).
The sensor consistsofanon-
magnetictube with non-
conductivelining, measuring
electrodes,excitationcoilsand
cables.Therearevarious
sensorversionsavailable
enablingconnectiontoadjacent
tubeswith flanges(type P)and
fittings(gasfitting type Gor
food industryfitting type V)or
waferwhichareinstalled
between flangesusing clamps
(type B). Non-conductivelining
can bemade oftechnical
rubber (types TG, MG or NG)or
Teflon (type T).
The converter isusedfor
generating excitationcurrent in
coils,processingofsignalfrom
measuring electrodes,
displayingofmeasured data
and generating output signals.
Current inexcitation coilshas
constant value250 mAor125
mAand ispulsegeneratedwith
alternating polaritytoavoid
permanent magnetization of the
sensor.Excitationpulse
frequencycan be chosenfrom
sixvalues–25 Hz,12,5Hz,
8,33Hz,6,25Hz,3,125Hzand
1,56 Hz.Excitation current of
250 mAwithexcitation
frequency3,125Hzissuitable
for all standard applications.
Other settingscanbeusedfor
specificapplications.Excitation
current and frequencyare
factorysetbeforesensor
calibrationandtheirlater
modificationsare notallowed.

on theendofexcitation pulse
whenmagneticfieldissteady.
Eachexcitationpulse is
followedbyrefreshing period.
Signalprocessing and
parametersetting are
performed digitallyand the
converter containsnosetting

Toensure correct measurement
and to avoidairlock,whole
sensor cross section shouldbe
flooded.Therefore never locate
the sensor inupper partsof the
pipelineor inverticalpositions
with liquid flowing downwards.

Correct function ofthe magnetic
flowmeter requiresperfect
electricalconnection between
the sensor andtheadjacent
pipeline,grounding potential
and the power supplyprotective
wire.
For the flanged sensor withthe
adjacent conducting pipeline,
flangesshouldbe electrically
connectedandthepipeline
grounded.
Ifthe adjacent pipelineis
non-conductive, groundingrings
shouldbe inserted initor
equivalent method shouldbe

Ifelectriccurrent flowsthrough
the pipeline,e.g.for pipeline
cathodicprotectionagainst
corrosion, thesensorshouldbe
electricallyisolatedfromthe
adjacent pipeline. The sensor
shouldbe bridged over using a
wire andgalvanicisolationof
the flowmeter power supply
shouldbeprovided so thatthe
flowmeter canbeisolatedfrom
allother devices.
Sensor grounding
Selection of suitable sensor lining and electrode material
Linings
Sensorshaveanon-conductive
liningfromvariousmaterials.
Choice ofmaterialdepends on
measured fluid characteristics.
• Technical rubber
Technicalrubber issuitablefor
lowaggressivefluidswith
operationaltemperaturesfrom
0.1°Cto70°C. It fitsfor most
water management and sewage
treatment applications.Itis
manufactured intwovariants
“TG” –with hard structureand
“MG” –withsoftstructure.Soft
structure isusedfor fluidswith
higher contentofabrasive
particles(e.g.sand). Itisnot
suitable for drinking water.
• Resistant rubber
Type “NG” issuitable for
mediumaggressivefluidswith
operationaltemperaturesfrom
0.1 °C to 90°C. It can beused
for measurement ofhot service
water, condensate etc., aswell
asfordrinkingwater.If
temperature 100 °C canbe
exceeded,Teflon (PTFE) lining
isrecommended.
• Teflone or Hallar
Type “T” isthe mostuniversal
liningfor aggressivefluidswith
operationaltemperaturesfrom-
20 °Cto 150°C. It issuitable for
chemicaland food industry
applications.
Electrodes
Choiceofmaterialofmeasuring
electrodesalsodependson
measured fluid characteristics.
• Stainless steel – “Ss”
Standardelectrodesaremade
ofstainless steelAISI 316Ti.
Theyare suitablefor allusual
water basedfluidsandfor lower
concentrationsofacidsand
caustics.
• Hastelloy C-22 – “Ha”
For somespecialapplications,
materialofhigher qualityshould
beused. HastelloyC-276
electrodesarecharacterizedby
increased resistanceagainst
acidsand caustics and usually
aresuitableformostof
industrialapplications.
• Titanium - „Ti“
Suitablefor someacids,
lyes,chlorine, ureaand
sewage.
• Platinum –“Pt”
Forparticularlyaggressive
fluidslikeconcentratedacids
andcaustics,chemically
extremelyresistant material
shouldbechosen –platinum.
However,highcostofthis
materialisitsessential
drawback.

1. Sensor
Thissubmenu relatestothe
sensor.
• Sensor constants – sensor
calibration constants
• Excitation frequency –of
sensor coils
• Excitation current –of
sensor coils
• Suppressed flowrate –
when flow rateislower than
thisvalue, itisconsidered
for zero. Thissetting isused
to suppress creeping flows.
• Number of samples – for
floating averaging that filters
measured flowratevalue.
Higher number ofsamples
providesmore stable flow
rate value, however it
increasestime constant and
causesdelayed reaction to
flowrate changes.
• Filters
♦ Noise filter partially
reducesjump changesbut
mainlyremoveslower
periodicalinterference.
Transient edgesare
rounded ascan beseen in
figure ofresponse to unit
jump. The filter isapplied
alreadyon input and thus
influencesimmediate flow
rate value and cumulated
volume calculated fromit.
The noise filter introduces
onlynegligibledelay(about
0.3 sec) and can be used
almost at allcircumstances.
♦ Dynamicfilter reduces
rapid jump changesofflow
rate. It protectsvery
effectivelyagainst high
short peakscaused by
interference. Unlike
averaging, dynamicfilter
cutsinput signaland
interferenceisnotincluded
in cumulated volume. It can
however cause delayofflow
rate jump change indication.
Thisfact should be
considered ifthe flowmeter
isused for dosing
applications.Response to

Correctmeasurement of flow

isconditionedbyfullflooding of
the wholesensor cross section
bymeasured liquid.Ifflooding
isonlypartial,the magnetic
flowmeter will indicate flow rate
higher thanreal.However, if
both electrodesarenot
immersed inliquid,interfering
voltagecan be generatedon
electrode wiresandthe
flowmeter canindicatetotally
randomvalues.Toavoid this
situation,thesensor canbe
equippedwithchecking

continuouslychecks if the
checking electrode isimmersed

message willbedisplayed and
zero flowratewill beindicated.
The checking electrodeis
connectedto terminal1.This
electrodecannot be retrofitted

Batching
Batching mode isused for
controlofexternalequipment
( valves,pumps) in order to
measure repeatedlythe preset
volume (batch). It isnot
recommended for batching of
verysmall volumes. The period
ofone batch hasto be min 30 s.
Electromagneticflowmeter
FLOMAG3000 hasvery
sophisticatedbatching
functions. It enablessimple
batching withmanualstarting
but also fullyautomaticbatching
byremote control.
Batching process isdivided
into4 phases.Single phases
are distinguished on LCD bya
symbolin square brackets.
Upper line showsremaining
volume in mlto theend ofthe
batch. Bottomline showshelp
for manualbatch control.
Phase0 - Stop
During phase 0 outputsare
inactive, no batching runs,
waitingfor start ofthe batching
process. Manualstart is
realized byholding button 3and
simultaneouspushing ofbutton
4 or fromoutside with the help
ofmoduleE in BatchStart
mode. During thatphase the
batchvolume isset. To enter
editmode it isnecessaryto
hold button2 and
simultaneouslypushbutton4.
Phase1 - Hold
Phase1 temporarybatch
interruption. Outputsgive signal
for interruptionofthe batch
(close valve, switch off pump).
Counted batch could ve
continuedagain bymanualstart
choosing Restartor from
outsidewith the help ofmodule
E in BatchStart mode. It is
possible also toabort the batch
bychoosing Reset or from
outsidewith the help ofmodule
E in BatchStopmode.
Phase2 - Run
During that phase runsthe
measuring ofthe batch (valveis
open, pump isrunning). This
mode can be interruptedusing
Phase1 (Hold) activated
manuallyor with the help of
module E inBatch Stop mode.
It ispossible also to abortit
choosing Resetor fromoutside
with the help ofmoduleE in
BatchStop mode. During this
phase there isnoreaction to
externalsignalBatch Start. If
there isno anypresetoutputs'
advance, after flowing ofthe set
batchvolume comesswitching
to phase 0 (Stop). Outputswill
send signalfor batch stop
(switchoff pump, close valve).
Becauseofthe late reaction to
the output signala partial
overflowofthe set batch
volume willtake place and
displaywill shownegative
volume. That'swhyitissuitable
to senda signalfor batch stop
in advanceasitisdescribed
below.
