Vortex Flow Sensors VA Di Vortex Flow Sensors VA Di also suitable for applications in condensation and particle laden gases Drawin g 1  actual flow rate  Measurable variable standard velocity Medium Other gases on request. Particles, condensation, humidity in the gas  charges in the gas caused by particles such as dust and fibres do not affect the measurement, as long as abrasion and agglomeration do not occur on the sensor  standard flow rate (in combination with pressure and temperature sensors)

Vortex Flow Sensor VA Di ZG1 - U291 - 7174 

primarily single-phase gas mixtures with air, nitrogen, oxygen, methane, natural gas, flare gas, ammonia, argon, carbon monoxide, steam ... as dominant component, combustion exhaust gas, bio gas, sewage gas.  relative gas humidity of less than 100 % does not affect the measurement uncertainty Design  measuring tube Functional principle  vortex meter for measuring flow rate and volume  ultrasonic measurement of the vortex sheddin g  low starting value  Advantages high measuring dynamics (up to 1 : 100)



depending on the density, condensation on the sensor may affect measurements. The vortex signal processing module VSM can help reduce measurement uncertainty if condensation is moderate; requirement: external evalutation unit instead of integrated transducer UVA  no moving parts  maximum fatigue strength Range and examples of application  corrosion resistant  operates to a large extent irrespective of gas composition



flow measurement, for example, of air, exhaust gas, process gas, bio and sewage gas, engine intake air, exhaust emissions, gases laden with particles, dust and fibres, superheated steam



low pressure drop
