Hoentzsch Vortex flow sensor VA40 ... ZG7 with integrated transducer UVA, capable of parameterization
Medium
primarily single-phase gas mixtures with air, nitrogen, oxygen, methane, natural gas, ammonia, argon, carbon monoxide, superheated steam
and biogas as dominant component.
Other gases on request.
Advantages
small starting value (0.5 m/s)
high measuring dynamics (1 : 80)
no moving parts
high time yield
corrosion resistant
operates largely irrespective of the gas composition
minor pressure drop
application in Ex-protection Category 3G and 3D (zone 2 and zone 22) permissible
Particles, humidity and condensation
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
relative gas humidity of less than 100 % does not affect the measuring uncertainty
slight condensation adsorption on the sensor does not affect the measurement
