Summary

The purpose of this experiment was to assess measuring errors in portable thermal anemometer operation. Nine anemometers, chosen among the most currently used, were tested in a wind tunnel operating at constant air velocity but with air temperature varying according to defined cycles. In each different cycle air temperature was increased, maintained above ambient temperature and then decreased. The errors in air velocity measurement caused by changes in air temperature are indicated. No correlation was established between error magnitude and sensor type or size.
