Air Velocity Meters
Air velocity meters are measurement devices used to report the speed of the air connected to the device. Air velocity meters are typically of two types - vane anemometers or pressure-based measurement systems. In vane anemometers the airflow spins a fan wheel and the resulting rotational speed is converted to an airflow measurement. The airflow measurement can be volumetric, such as cubic feet per minute (CFM), or can be converted to an air speed based on the known flow area. In a pressure-based measurment system, the pressure and temperature of the airflow is measured by the device and the ideal gas law is used to convert these parameters to a corresponding air speed.
