Vertical Roller Mill air flow measurement for cement plant ...

Air flow measurement at VRM is a difficult topic in the cement industry, this is due to the short distance turbulent air duct and extremely high temperature dusty condition between the cyclone filter to the VRM. Having a precise VRM air flow measurement enables operator to save energy used by the ID fan motor.


3 Simple Ways to Measure Air Flow - wikiHow

2. Turn on the anemometer and set it to measure air flow. If you just recently purchased your anemometer, insert batteries or plug it in to power it up. Once it's on, change the measurement settings to CFM so you can measure air flow. A typical anemometer will have a button that reads "Unit" or "Units.".


MEASUREMENT OF AIRFLOW IN A SIMULATED …

airflow, the resultant air speed values will not be accurate. Uultrasonic anemometers have been designed for measuring airflow velocities in three-dimensional space. With a three-axis anemometer, orientation of the instrument with flow direction is not necessary to measure speed. The anemometer can also record rapid changes in velocity.
