VU 570 – Vortex ultrasonic flow sensor
For technical gases and mixed gases – independent from gas composition – integrated pressure and temperature compensation – larger measuring range than common Vortex sensors
Field of application:
- Technical gases
- Mixed gases
- Compressed air in PET bottles production
- CO2
- LPG
- Propane
- Crypton
Benefits at a glance:
- Measurement of standard volume flow, operating volume flow, mass flow
- Suitable for unknown/changing gas compositions and mixed gases
- The innovative measuring principle grant a precise flow measu- rement in different gases
- Suitable for quickly changing temperature and pressure chan- ges as well as high mass flows
Advantages towards common mechanic gas meters:
- No moving parts – no wearing
Advantages towards common Vortex sensors:
- Precise measurement already from 0.3 m/s
