An anemometer measures wind speed or, more generally, the speed of air or gas flow. It can be used in weather stations, ducts, and other airflow measurements.

Quick Scoop

  • Main measurement: wind speed.
  • Broader use: velocity of gases or air in a flow, including duct airflow.
  • Sometimes related: some anemometers can help estimate flow direction or pressure, but their core job is measuring speed/velocity.
