VA 521 – Compact Inline flow meter for compressed air and other gas types
Downloads
- Compact design, no inlet/outlet sections needed.
- Accurate for small and large flow rates.
- Low maintenance, suitable for non-corrosive gases.
Reduce your energy costs and increase your sustainability with the VA 521. Monitor the consumption of each machine and analyze your leakage flows with just one measuring device.
- Measurement of mass flow rate, output of standard volume flow rate without additional measurement of pressure and temperature.
- Compact device for installation in limited space, no inlet and outlet sections necessary due to the integrated flow straightener
- Highly accurate at small as well as high flowrates
- Easy installation and removal of the sensor, the integrated measuring section can remain in the line for cleaning or recalibration of the sensor and can simply be closed with a sealing cap
- No moving parts, therefore low maintenance required
- Can be used for compressed air and non-corrosive gases such as nitrogen, oxygen, argon, helium, etc.
