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
