Dust collection systems require the proper airflow to be operating correctly. If not enough air is going through the system, dust isn’t being properly removed from the collection points and the dust collection equipment (baghouse, cartridge collectors, cyclones, etc.) might not be operating correctly. However, if too much air is being pulled through the system, a variety of issues might ensue, such as product being lost, removal efficiency lowered, utility usage increased.
Conventional Way to Measure Airflow
The normal way to measure airflow is to insert a pitot tube in the ductwork to measure the air velocity in an airstream, and then calculate the velocity (and airflow). This is a manual process that requires a trained individual. It is time consuming and to a certain degree an art, since the velocity in a ductwork changes depending how close to the wall you are.
Effective Way to Measure Airflow
Obviously, you cannot walk next to a piece of equipment or meter and check the velocity through the ductwork. However, if you have a cyclone dust collector you can. Cyclone pressure drops are based on the airflow through them. The more air you send through a cyclone, the higher the pressure drop. Each cyclone design has its own equation to determine pressure drop based on the airflow. With this equation, you can estimate the airflow based on the pressure drop in your cyclone.
