Anemometer

An Anemometer is an instrument used to measure the speed and direction of wind or airflow. It is widely used in meteorology, environmental studies, and industrial applications where ventilation and airflow monitoring are essential. The most common type is the cup anemometer, consisting of three or four hemispherical cups mounted on horizontal arms attached to a vertical shaft. When wind blows, the cups rotate, and the speed of rotation is proportional to wind velocity. Another type is the vane anemometer, which measures both wind speed and direction, while hot-wire anemometers use electrically heated wires to detect airflow by monitoring cooling effects. Ultrasonic anemometers employ sound waves for precise, maintenance-free measurements. Anemometers are crucial for weather forecasting, aviation safety, HVAC system efficiency, and research in fluid dynamics. Modern digital anemometers provide instant readings and data logging, making them highly reliable tools for wind analysis.
