The Marine Anemometer WS-12 is an instrument for wind speed and direction. It can measure relative wind speed
(accuracy ±5%, min 0.1m/s), relative wind direction (accuracy 1°).
The WS-12 wind sensor must be reading representative values for the wind and therefore the wind sensor must be
reading clear wind, unobstructed by any wind shadow from structures.

Principle of measurement
The wind speed sensor has a rotor with three wind cups which spins as the wind moves past the boat. The Wind speed
sensor measures how fast the rotor is spinning to calculate the wind speed.
The wind direction sensor has a wind vane which points in the direction that the wind is coming from. The wind direction
sensor electronically senses the direction the wind vane is pointing.
