MEASURING ACCURACY
For the best possible accuracy, it is recommended to install the air volume damper so that it is preceded by a straight duct, at least 3 x D safety dis-
tance.
Valid when the damper blade opening is > 30%. Recommended maximum air velocity with shorter than 3 x D safety distances is 8 m/s.
Adequate safety distance is recommended after the type of flow disturbance (3 x D).
With sizes 500 and 630 should the safety distance be at least 3 x D.
The motor/ultrasound shall be placed as shown on the pictures above.
*) recommended position
*)
When using the minimum safety distance after the type of flow disturbance, the installation parameter must be set according to the commissioning
section (p.9-10) to achieve the accuracies.
