Vortex Flow Sensors VA Di ________________________________________________________________________________________________ Vortex Flow Sensors VA Di also suitable for applications in condensation and particle laden gases Measurable variable  actual flow rate  standard velocity standard flow rate (in combination with pressure and temperature sensors) Design  measuring tube Functional principle  vortex meter for measuring flow rate and volume  ultrasonic measurement of the vortex shedding Advantages  low starting value  high measuring dynamics (up to 1 : 100)  no moving parts  maximum fatigue strength  corrosion resistant  operates to a large extent irrespective of gas composition  low pressure drop  easy adjustment to process parameter Medium  primarily single-phase gas mixtures, e.g. air, nitrogen, oxygen, methane, natural gas, flare gas, ammonia, argon, carbon monoxide, superheated steam, combustion exhaust gas, biogas, sewage gas. 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 Other gases or gas mixtureson request  measurement uncertainty Range and examples of application  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 remains unaffected by a relative gas humidity of less than 100 % and a slight accumulation o
