The wind meter is very simple, affordable and gives the maximum speed up to any speed that you want.
It is mechanical and more reliable then many electronic ones. The instrument can be remotely reset from the ground by pulling a cable to draw back a bright marker like a pin in a minimum-maximum thermometer. It has a wind sock which means it is not critical to have it vertical for an accurate measurement. Therefore, it does not matter if the pole supporting it leans a little. Hence the instrument can be clamped to a pole that is attached to the top of a tree where the pole sticks above the tree and only needs the tree for a support. The low cost and ease of installation means many more wind meters could be installed. This would help weather observation and forecasting because there are a lack of wind meters around. I also recommend the system for people with electronic anemometers as a back up, because electronic systems can fail at vital times such as in a cyclone. In severe storms there is a lot of moisture, along with power failures, that can cause problems with electronics.
As the wind meter can be supported by a tree, it saves the time and cost of building a mast. To obtain accurate wind readings, the instrument should be above the highest tree in the area. Hence it can be expensive to build the mast which is required for other wind meters that must be vertically mounted..
The wind meter consists of a wind vane and a wind sock attached to a spring that stretches as the wind increases.
It indicates both direction and speed.
