Answer:
AnemometerIntroduction to Air Velocity MeasurementAn anemometer is an instrument used to measure the speed or velocity of air (gases) either in a contained flow, such as airflow in a duct, or in unconfined flows, such as atmospheric wind. To determine the air velocity, anemometers detect change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow.
The hot wire anemometer is the most popular kind of constant-temperature devices. It consists of an electrically heated, fine-wire element (0.00016 inch in diameter and 0.05 inch long) supported by needles at its ends. While hot wire are best suited for clean gases at low velocities, venturi meters can also be considered for some liquid (including slurry) flow applications
