An experimental characterization of flow behavior in an experimental facility for type S Pitot tube calibration by means of velocity profiles and turbulence is present. The measurements were carried out with a Pitot static tube and a hot wire anemometer at 4, 8 and 12 diameters from fan outlet for maximum velocities from 5.8 m/s to 35 m/s. The velocity and turbulence profiles were measurement at the discharge of the duct, in order to evaluate the possibility to use this installation for anemometer calibration too. Results showed that plane located at 12 D from fan outlet is adequate for establish the test section for type S Pitot tube calibration. Measurement in the exit of ducted outlet showed a good flow quality for anemometers calibration.
