Which Device Measures Wind Speed? Understanding the Anemometer

Discover how anemometers measure wind speed with rotating cups and their role in meteorology and wind energy.

195 views

An anemometer is the device used to measure the speed of wind. It typically consists of three or four cups attached to horizontal arms, which spin around a vertical rod as the wind blows. The speed of rotation is directly proportional to the wind speed, and this data is then converted into a readable measurement. Anemometers are essential tools in meteorology, sailing, and wind energy industries.
