Description

CS Instruments VU 570 – Vortex Ultrasonic Flow Sensor

CS Instruments 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 bottle production
CO2
LPG
Propane
Krypton

Advantages:

Precise measurement starting at 0.3 m/s
Suitable for unknown or changing gas compositions and mixed gases
Rough industrial applications can be realized due to robust aluminum 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 diameter

Technical Details:

04…20 mA, pulse, and a Modbus RTU (RS 485) interface as standard
Optional interfaces such as Modbus TCP (Ethernet), PoE, M-Bus
Pressure ranges up to 40 bar
Protection class IP 67
Temperature ranges from -40°C to 100°C
Integrated display for showing the measured values
Available from DN15 to DN80
Settings are adjustable via the buttons on the display
The 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

Features

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
