An magneticflowmeter isused
for volumeflowmeasurement of
electricallyconductiveliquids.

Principle of measurement
Technical solution
The magneticflowmeter itself
consistsoftwobasicparts–a
flow sensor andaconverter.
The converter can beeither an
integralpart ofthe sensor
(compactversion) or separated,
connectedwiththesensorus-
ing a cable (remote version).
The sensor consistsofanon-
magnetictube with non-
conductivelining, measuring
electrodes,excitationcoilsand
cables.There are varioussen-
sor versionsavailableenabling
connectiontoadjacent tubes
with flanges(type P)and fittings
(gasfitting type Gorfood indus-
tryfittingtype V)or wafer which
are installedbetweenflanges
using clamps(type B). Non-
conductivelining can be made
oftechnicalrubber (types TG,
MG or NG) or Teflon (type T).
The converter isusedfor gener-
atingexcitation current incoils,
processing ofsignalfrommeas-
uring electrodes,displayingof
measured data andgenerating
output signals.Current inexci-
tation coilshasconstant value
250 mAor 125 mAand ispulse
generated with alternatingpo-
larityto avoidpermanent mag-
netizationofthesensor.Excita-
tionpulsefrequencycanbe
chosen fromsixvalues–25Hz,
12,5Hz,8,33 Hz,6,25Hz,
3,125Hzand1,56Hz.Excita-
tion currentof250 mAwithex-
citation frequency3,125 Hzis
suitablefor allstandard applica-
tions.Othersettingscanbe
used for specificapplications.

quencyarefactorysetbefore

The flowmeter will givethebest
resultswhen flowofliquidis

Ifmore interfering elementsare
present near the sensor (e.g.

number ofthese interfering ele-
ments.

Ifwater inthepipelineis

The sensor can workboth in
horizontaland verticalpositions;

trodesinsidethe sensor must
alwaysremaininhorizontalpo-
sitionandtapping ofthe sensor
shouldbedirectedupwardsat
horizontalinstallations.

For verticalinstallations,liquid

Fig. 9- Verticalinstallation
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.
Fig.10 - Danger ofair lock
Ifpermanent flooding ofwhole
pipeline cross section cannot be
ensured, itispossibleto locate
the sensor inalowwatertrap
sothat itcan be alwayscom-
pletelyflooded. Freewaterdis-
charge shouldbe located2DN
higher than the sensor.

Toavoidvibrationsthat could
damage the sensor, ensurethat
the adjacent pipelineisalways
supportedasnear tothesensor
aspossible.

Correct function ofthe magnetic
flowmeter requiresperfectelec-
tricalconnection betweenthe
sensor and theadjacent pipe-
line, grounding potentialand the
power supplyprotectivewire.
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

rosion,thesensorshouldbe
electricallyisolatedfromthe
adjacent pipeline. The sensor
shouldbe bridged over using a
wire andgalvanicisolationof

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
lowaggressivefluidswithop-
erationaltemperaturesfrom0.1
°C to70°C.It fitsfor mostwa-
ter management andsewage
treatment applications.Itis
manufactured intwovariants
“TG” –with hard structureand
“MG” –withsoftstructure.Soft
structure isusedfor fluidswith
higher content ofabrasiveparti-
cles(e.g.sand). It isnotsuit-
able for drinking water.
· Resistant rubber
Type “NG” issuitablefor me-
diumaggressivefluidswithop-
erationaltemperaturesfrom0.1
°C to 90°C.It can be usedfor
measurement ofhot service
water, condensate etc., aswell
asfor drinking water. Iftem-
perature100 °C canbeex-
ceeded,Teflon (PTFE) lining is
recommended.
· Teflone or Hallar
Type “T” isthe mostuniversal
liningfor aggressivefluidswith
operationaltemperaturesfrom-
20 °Cto 150°C. It issuitable for
chemicalandfood industryap-
plications.
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
be used. HastelloyC-276 elec-
trodesare characterized byin-
creased resistanceagainstac-
idsand caustics and usuallyare
suitablefor mostofindustrial
applications.
· Titanium - „Ti“
Suitablefor someacids,
lyes,chlorine, urea and sew-
age.
· Platinum –“Pt”
For particularlyaggressiveflu-
idslikeconcentrated acidsand
caustics,chemicallyextremely
resistant materialshouldbe
chosen –platinum.However,
highcostofthismaterialis its
essentialdrawback.
