- Abstract:
- A primary air velocity meter calibration standard comprising of a precisely controlled wind tunnel system and a Laser Doppler Anemometry (LDA) system was developed for the calibration of air velocity meters from 0.2 m/s to 60 m/s with measurement uncertainties of less than 0.18% to 0.63%. The LDA system is used to verify the wind speed in the test section of the wind tunnel, and provide traceability to the SI for air speed measurements.
