Anemometers measure wind speed and direction using a variety of methods, including:
-
-
Mechanical anemometersThese anemometers use cups or a propeller attached to a wheel to measure wind speed. The cups or propeller rotate as the wind blows, and the number of rotations is counted to calculate wind speed.
-
Sonic anemometersThese anemometers use sound waves to measure wind speed and direction. They have no moving parts and are often used in aircraft and scientific wind turbines.
-
-
Digital anemometersThese anemometers measure wind speed, velocity, and direction by converting mechanical energy into electrical energy.
Anemometers are used in many applications, including:
- Measuring airflow in air conditioners and ventilation units
- Measuring gas flow in turbulent atmospheric conditions
- Measuring wind velocity and direction in airspace travel
- Measuring wind pressure and direction in weather stations
