An instrument to measure wind speed Wind directions are always reported as the direction winds are coming from - a southerly wind pushes air from the south to the north
(wind) (meas) An instrument for measuring WIND SPEED F - anenometre S - anemometro
Instrument for measuring the speed of airflow. The most familiar instruments for measuring wind speeds are the revolving cups that drive an electric generator (useful range approximately 5-100 knots). For very low airspeeds, a unit in which revolving vanes operate a counter measures the airspeed. For strong, steady wind speeds (in wind tunnels and aboard aircraft in flight), a pitot-tube anemometer is often used; the pressure difference between the interior of the tube and the surrounding air can be measured and converted to airspeed
