Procedure for Measuring Static Pressure

1. Select the location for the static pressure reading and drill a ¼" hole.
You may wish to paint a circle around the hole and number it for
future convenience.
2. Assemble the Velometer
readings as described above.
3. Place the rubber cup of the probe firmly over the hole, and read the
static pressure on the black or red "Inches of Water Gauge" scale.
4. Record the reading on an appropriate air balancing worksheet.

Procedure for Air Flow Measurement in Ducts

To calculate the air volume passing through a duct, measure the
average velocity inside the duct, determine the cross-sectional area of
the duct, and apply the following equation:
Q = A x V
Where
Q = Volume flow rate
A = Cross-section area
V = Average duct velocity
