Measuring Flow

Once the SMART Air Hood™ is placed and supported by the pole, airflow can 
be viewed on the handheld by tapping METER MODE.

The following screen shows airflow measurements using the default Diffuser. 
Note that the default diffuser is 

Step Down Three Cone Register

. In addition to 

measuring flow, barometric pressure, relative humidity, and air temperature 
can also be measured.

In order to read flow accurately, the correct diffuser style must be selected. To 
determine the diffuser style, look through the translucent body of the SMART 
Air Hood™ or remove the SMART Air Hood™ from the diffuser. In the below 
example, airflow is being measured from a 

Plaque Register 

diffuser style.

In order to change from Step Down Three Cone Register diffuser style, simply 
tap on the diffuser icon. The following screen will appear, showing the entire 
library of diffuser styles.

Tap on the appropriate icon to select that diffuser style, which in this example 
is the 

Plaque Register

. Now the Plaque Register diffuser style is selected 

assuring accurate flow measurements.
