Abstract : A dual pivoting vane having a miniature dual bead thermistor anemometer at its upstream extremity and with light beam angular position sensors on the pivot axes provides a sensitive velocity vector sensor for measuring both magnitude and direction of low velocity airflow relative to a three-dimensional reference space of the body carrying the velocity vector sensor.
