Which instrument measures wind direction?

Explanation:
Wind direction is determined by an instrument that always points toward the source of the wind. A wind vane does exactly that: it rotates to align with the wind and points in the direction from which the wind is blowing. That direct indication makes it the instrument for measuring wind direction. The barometer measures atmospheric pressure, the anemometer measures wind speed, and an aerovane can provide speed (and, with the vane, direction) but the device whose primary function is to show direction is the wind vane.
