A
wind vane is an instrument that measures wind direction while anemometer
measures wind speed.
PRINCIPLES OF WIND VANE AND ANEMOMETER
- The measuring principle of anemometer is simple: the stronger the wind blows, the faster the half-open plastic cups turn. The speed of the cross rotation determines the wind speed.
- The cup anemometer records the number of rotations per minute and thus the wind speed very accurately.
- Information obtain by wind vane and anemometer are converted and can be read directly form ship’s bridge.

- Information generated by wind vane and anemometer are converted and can be read directly form ship’s bridge.
- Through advance technology, wind speed and direction can be seen directly through a display unit in the ship’s bridge and no need for manual calculation.
