For maximum accuracy, observe the following precautions:

measuring procedures.
2. Make a complete and accurate velocity reading.
3. Record the velocity measurements on a diffuser air balancing
worksheet as shown.

4. When the procedures instruct you to apply an average velocity
reading, divide the opening into a number of equal areas and
determine an average of single readings taken at the center of the
equal areas.
5. When making a record of the measurements, include room location,
outlet model, flow factor, design air volume if known, measured
outlet velocity and calculated air volume.
