Also, they can be coupled having a radial damper, a crown damper and an opposed-blade damper for airflow Command.
When you are unable to get yourself a stream hood, you could consider using an anemometer which has a Screen with a little supporter connected to it. Anemometers are utilized to measure air velocity as an alternative to air volume or airflow in CFM or m3/hr.
