Function and system design
Measuring principle VortexmetersworkontheprincipleoftheKarmanvortexstreet.Whenfluidflowspastabluffbody,
vorticesarealternatelyformedonbothsideswithoppositedirectionsofrotation.Thesevorticeseach
generatealocallowpressure.Thepressurefluctuationsarerecordedbythesensorandconvertedto

device.Therefore,thefrequencyofvortexsheddingisproportionaltothevolumeflow.

Lifelongcalibration
Experiencehasshownthatrecalibratedmeasuringdevicesdemonstrateaveryhighdegreeof
stabilitycomparedtotheiroriginalcalibration:Therecalibrationvalueswereallwithintheoriginal
measuringaccuracyspecificationsofthedevices.Thisappliestothemeasuredvolumeflow,the
device'sprimarymeasuredvariable.
Varioustestsandsimulationhaveshownthatoncetheradiioftheedgesonthebluffbodyareless
than1mm(0.04in),theresultingeffectdoesnothaveanegativeimpactonaccuracy.
Iftheradiioftheedgesonthebluffbodydonotexceed1mm(0.04in),thefollowinggeneral
statementsapply(inthecaseofnon-abrasiveandnon-corrosivemedia,suchasinmostwaterand
steamapplications):
• Themeasuringdevicedoesnotdisplayanoffsetinthecalibrationandtheaccuracyisstill
guaranteed.
• Alltheedgesonthebluffbodyhavearadiusthatistypicallysmallerinsize.Asthemeasuring
devicesarenaturallyalsocalibratedwiththeseradii,themeasuringdeviceremainswithinthe
specifiedaccuracyratingprovidedthattheadditionalradiusthatisproducedasaresultofwear
andteardoesnotexceed1mm(0.04in).
