This study proposes a new design idea to measure wind speed and direction using drag force. For this aim, load cells which are get aligned with the geographical directions were used. A prototype was built and tested in a wind tunnel located at WEAR Laboratory in Erciyes University. The tests were performed for the direction of 225 between 5 m/s and 25.2 m/s and the outputs were compared with reference velocities. The results were shown that the mean measurement errors of the new design were less than 3% and the mean direction errors were less than 3 respectively, which provided WMO accuracy requirements.
