Frequently Asked Questions:

Q. Do anemometers need calibration?

A. Anemometers that detect wind potential must be calibrated before and after the measurement period.

Q. How are anemometers calibrated?

A. The usual setting for an anemometer calibration is a wind tunnel with continuous, pre-established air temperature and atmospheric pressure. The wind speed measurements at meteorological masts and, consequently, the site assessment for proposed wind farms, are based on this calibration.

Q. What are the four types of anemometers?

A.

• Thermal Anemometers
• Vane Anemometers
• Thermal Anemometers with Velocity / Temperature Profiling
• Cup Anemometers
