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.   HOW THE DATA IS CONVERTED                                                     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.
