Technology Fundamentals: Vortex Shedding PrinciplePhysics of Operation The sensor operates on the von Kármán vortex street principle:Bluff Body: A trapezoidal shedder bar (316 SS) mounted perpendicular to flowVortex Generation: As fluid passes the bluff body, alternating low-pressure vortices detach at a frequency proportional to flow velocity (f=St?v/df=St?v/d)StSt = Strouhal number (dimensionless constant)vv = Flow velocitydd = Bluff body widthDetection: Piezoelectric crystals embedded in the shedder bar convert vortex-induced pressure fluctuations into electrical pulsesSignal Processing: Paired transmitter calculates volumetric flow (Qv=f?A/KQv=f?A/K)AA = Pipe cross-sectionKK = Meter coefficientAdvantages Over Alternative TechnologiesTechnologyTurndownAccuracyMaintenanceSteam/Gas PerformanceVortex (8800D)20:1±0.65%NoneExcellentOrifice Plate4:1±2%HighPoorTurbine10:1±0.5%HighLimitedUltrasonic100:1±0.5%LowCost-ProhibitiveProduct ParametersParameterSpecificationAccuracy (Liquid)±0.65% of rate (≥0.3 m/s water)Accuracy (Gas/Steam)±1.0% of rate (≥3 m/s air)Repeatability±0.15% of readingTurndown20:1 (Velocity-dependent)Rangeability100:1 (with transmitter compensation)Temperature Range-40°C to 450°C (-40°F to 842°F)Pressure Rating1480 psig @ 38°C (102 barg)Burst Pressure4x rated pressureVibration2g @ 10-55Hz, 20g @ 2000HzIV.
