Accurate anemometer calibration can only be performed in a wind tunnel. However, the installation of such a facility involves tremendous investment, and its setup and maintenance are not easy tasks. This section describes some simple methods of checking anemometer operation to achieve the minimum required level of performance. Comparison by Beaufort Scale Comparing wind speeds …
To reduce the measurement uncertainties, first the anemometer has to be calibrated at normal ambient conditions in an accredited wind tunnel. Subsequently a measurement in the variable air density wind tunnel is performed at nearly the same temperature and pressure prevailing during the first measurement. The anemometer itself serves as a transfer standard. With both …
