Vortex Flow Sensor VA40 ... ZG7 - U307 - 7174 

primarily single-phase gas mixtures with air, nitrogen, oxygen, methane, natural gas, ammonia, argon, carbon monoxide, superheated steam ... and biogas as dominant component. /h] in air/gases  conversion to standard velocity/standard volume flow rate by input parameter working pressure and temperature Measuring range  0.5 ... 40 m/s Advantages  small starting value (0.5 m/s)  high measuring dynamics (1 : 80)
Vortex Flow Sensor VA40  no moving parts  high time yield Functional principle  corrosion resistant  vortex meter for measuring flow velocity, flow rate and volume  operates largely irrespective of the gas composition  ultrasonic measurement of the vortex shedding
