The dial shows the wind speed.
A wind sock s movement and shape also can show wind strength.
The normal unit of wind speed is the knot nautica l mile per hour 0 51 m sec 1 1 15 mph.
The three cup anemometer determines wind speed based on how fast the cup wheel spins and wind direction from the cyclical changes in cup wheel speed.
As the wind flows over the windmill the speed and direction of the wind can be measured with this instrument.
These types of instruments are used by the wind energy industry both for wind resource assessment and turbine control.
