Wind socks measure the direction of the wind when the wind blows into the open end and the sock points the way the wind is blowing. Wind socks can also measure the strength of the wind. If a wind sock is flapping about gently the wind is only light. If a wind sock sticks out in a straight line the wind is much stronger.
A wind sock is used to show the direction of the wind.
A wind vane or a wind sock.

A wind sock is used to show the direction of the wind.
A wind sock detects and shows the direction of the wind. It is a qualitative instrument and, ad best can be said to inticate the four or eight compass directions (N,S, E, W, etc)
The appearance of the wind sock gives a broad approximation to the wind speed, and a pretty good indication of the wind direction.
A wind sock, or wind cone.
A wind vane or a wind sock.
The wind direction is measured with wind vanes or wind socks. Sexagesimal degrees.
velocity direction indicator like a wind sock
well to help you its not wind speed if you need this answer for are you smarter than a 5th grader
