Frequently Asked Questions (FAQ)

1. What fluids can the AFV30S measure?
   It measures liquids, gases, and steam, including corrosive and high-temperature fluids.

2. Is the AFV30S suitable for high-pressure applications?
   Yes, it can handle pressures up to 10 MPa, depending on the model.

3. How does the vortex flowmeter work?
   It detects vortices generated by a bluff body, converting their frequency into flow rate.

4. What is the typical accuracy of the AFV30S?
   ±1.0% for liquids and ±1.5% for gases/steam.

5. Can it be used in hazardous areas?
   Yes, it is ATEX and IECEx certified for explosive environments.

6. Does it require regular calibration?
   No, its stable design minimizes drift, reducing calibration frequency.

7. What communication protocols are supported?
   HART, BRAIN, and Foundation Fieldbus (FF).

8. How is the AFV30S installed?
   It requires straight pipe sections (10D upstream, 5D downstream) for optimal accuracy.

9. What maintenance is needed?
   Periodic inspection for debris and verification of electrical connections.

10. Can it measure bidirectional flow?
    No, it is designed for unidirectional flow measurement.
