give me an example of anemometers

One example of an anemometer is a cup anemometer. It consists of a vertical shaft with three or more cups mounted on horizontal arms at equal distances from each other. As the wind blows, it causes the cups to rotate, and the speed of rotation is directly proportional to the wind speed. The cup anemometer is commonly used in weather stations and wind turbines to measure wind speed.

shorten this please
