Measuring Airflow with a Vane

Measuring with the Rotating Vane Anemometer

For highly accurate quick measurement, the rotating vane anemometer is the best way to measure airflow. Vane anemometers have several advantages over any other method. The primary advantages are speed, accuracy, and ease of use. Vane anemometers do not require air density compensation due to air temperature, humidity, or atmospheric pressure.  The mini vane allows for a full duct traverse with an automatic calculation of the CFM in the duct if the dimensions are input into the instrument before the measurement is taken. It is imperative that the ducting attached to the appliance, and the base pan, if side returned is used, is sealed.  A large vane can be used at the registers to proportional balance the system or for accurately measuring airflow at the return
