VU 570 – Vortex ultrasonic flow sensor
Downloads
- Suitable for unknown/changing gas compositions
- No moving parts – no wearing
- Precise measurement already from 0.3 m/s
For technical and mixed gases – independent of gas composition – integrated pressure and temperature compensation – larger measuring range than many current Vortex flow meters.
- 04…20 mA, pulse and a Modbus RTU (RS 485) interface as standard
- Optional interfaces such as Modbus TCP (Ethernet), PoE, M-Bus
- Pressure range up to 40 bar
- Protection class IP 67
- Temperature range from -40°C to 100°C
- Integrated display for showing the measured values
- Available from DN15 to DN80
- Settings adjustable via the buttons on the display
- Main counter reading can be reset via the display
- For velocities from 0.3 m/s to 30 m/s
- High accuracy of 1% deviation of the measured value
Benefits at a glance
- Precise measurement starting at 0.3 m/s
- Suitable for unknown or changing gas compositions and mixed gases
- Rough industrial applications can be realised due to robust aluminium housing
- Measures operating volume flow and mass flow
- Measurement of the standard volume flow through integrated pressure and temperature measurement
- The innovative measuring principle guarantees precise flow measurement in different gases
- Suitable for rapidly changing temperature and pressure changes as well as large mass flows
- Larger measuring span than usual vortex flow sensors
- No moving parts, therefore low maintenance effort
- Negligible low pressure loss due to negligible low blockage of the diamete
Field of application:
- Technical gases
- Mixed gases
- Compressed air in PET bottles production
- CO2
- LPG
- Propane
- Crypton
