A wind vane has a horizontal bar (sometimes it's a tube or shaft), which is mounted upon a circular pivot point that allows the bar to freely spin around in a horizontal plane pointing in any direction of the wind. A tail is placed at one end of the bar and the other end is used as the direction indicator (the pointer). The tail has more wind resistance than the small pointer, so a wind will always force the tail. This points the indicator (the pointer) into the wind to correctly show the wind direction. Often this pivot point is placed just slightly close toward the point than the tail. This adds leverages to the mechanical energy of the wind force placed upon the tail, which allows the indicator to correctly point into the wind even with low wind speeds. A windsock, often seen at airports or near helicopter pads points the opposite way of a weather vane - a windsock points into the direction where the wind is going, not from where it came like the wind vane.
The wind vane rotates freely on a veritical rod and becomes aligned by the direction of the wind.
Weather vane is for direction and anemometer is for speed
Wind vane
The weather vane, also known as the wind vane, tells you which direction the wind is blowing.
A weather vane measures the direction of the wind. It consists of a rotating arrow or figure mounted on a fixed vertical rod, aligned with the cardinal directions. The vane rotates freely to indicate the direction from which the wind is blowing.
it tells you what direction the wind is coming from and it also tells you if you are going in the right direction
A weather vane is also known as a wind vane. It has also been referred to as a weather clock.

Vane, as in a weather vane
A weather vane shows the direction the wind is blowing from.
Your weather vane came through our window during last night's storm.
No. A weather vane only shows the wind direction.
A weather vane is a device which allows you to see from which direction the wind blows.

The "o" on a weather vane stands for "origin," indicating the direction from which the wind is blowing.
The weather vane originated in Athens, Greece, as a symbol of Christianity on the rooftops of churches. The original weather vane was always in the shape of a rooster but now there are many varieties.
The weather vane indicates the direction of the wind.A. 'The vane in that turbine needs an overhaul'.Vane is a broad blade attached to rotating axis or wheel.
It would be coileach gaoithe (weather cock) or madra feothain (dog vane).
