Every effort has been taken in the production of this data sheet to ensure it’s accuracy. Axio can not, however, accept responsibility for any damage, expense, injury, loss or consequential loss

resulting from any errors or omissions. Axio has a policy of continuous improvement and reserves the right to change this specification without notice.

InstallationMount the air velocity probe in the duct.

Adjust the speed of the fan to give a known air velocity. turn the static pressure probe so that a differential pressure

corresponding to the to the known air velocity is measured across the two probes. Lock in position using the pan-head

screws on the flanges

If the fan speed adjustment is not possible measure the air velocity with an anemometer or similar carry out procedure as

above.

Calculation

The air velocity probes can be connected to an Air differential pressure transmitter as per the above drawing

to select the correct range of AX-ADPT see the table on page 3

The output of the Air diferential pressure represents the air velocity and is defined by the following equation:-

Velocity squared = 2 x Velocity pressure

------------------------------

1.2

This calculation should be performed in a controllers stategy to air velocity in m/sec

How to use the Air velocity v differential pressure chart

Take the Left hand column take the relevant velocity in m/sec

then move along the top column to the relvant velocity in 0.1m/sec

Read the diferential pressure required in pascals

size the AX-ADPT to the next size above the the pascal range
