nnnnflow measuring technology
nnnnVortex Flow Sensors VA Di
nnnnalso suitable for applications in condensation and particle laden gases
nnnnMeasurable variable
nnnnactual flow rate
nnnnstandard velocity
nnnnstandard flow rate (in
nnnncombination with pressure
nnnnand temperature sensors)
nnnnDesign
nnnnmeasuring tube
nnnnFunctional principle
nnnnvortex meter for measuring
nnnnflow rate and volume
nnnnultrasonic measurement of
nnnnthe vortex shedding
nnnnMedium
nnnnprimarily single-phase gas
nnnnmixtures with air, nitrogen,
nnnnoxygen, methane, natural
nnnngas, flare gas, ammonia,
nnnnargon, carbon monoxide,
nnnnsteam ... as dominant
nnnncomponent, combustion
nnnnexhaust gas, bio gas,
nnnnsewage gas.
nnnnOther gases on request.
nnnnParticles, condensation,
nnnnhumidity in the gas
nnnncharges in the gas caused
nnnnby particles such as dust
nnnnand fibres do not affect the
nnnnmeasurement, as long as
nnnnabrasion and agglomeration
nnnndo not occur on the sensor
nnnnrelative gas humidity of less
nnnnthan 100 % does not affect
nnnnthe measurement
nnnnuncertainty
nnnnAdvantages
nnnnlow starting value
nnnnhigh measuring dynamics
nnnn(up to 1 : 100)
nnnnno moving parts
nnnnmaximum fatigue strength
nnnncorrosion resistant
nnnnoperates to a large extent
nnnnirrespective of gas
nnnncomposition
nnnnlow pressure drop
nnnneasy adjustment to process
nnnnparameter
nnnnRange and examples of
nnnnapplication
nnnnflow measurement, for
nnnnexample, of air, exhaust
nnnngas, process gas, bio and
nnnnsewage gas, engine intake
nnnnair, exhaust emissions,
nnnngases laden with particles,
nnnndust and fibres, superheated
nnnnsteam
nnnndepending on the density,
nnnncondensation on the sensor
nnnnmay affect measurements.
nnnnThe vortex signal processing
nnnnmodule VSM can help reduce
nnnnmeasurement uncertainty if
nnnncondensation is moderate;
nnnnrequirement: external
nnnnevalutation unit instead of
nnnnintegrated transducer UVA
