2 .1 .6 Point of installation and steadying zones
The mounting attitude is unimportant. It is generally sufficient to have a distance of 10 pipe
diameters (D) before the monitoring head if the velocity profile is only slightly disturbed. For
much disturbed velocity profiles, above all for a superimposed swirl-flow, there should be a
distance of 20 to 50 pipe diameters (D) before the monitoring head in order to eliminate high devia-
tions in the values measured.
It is generally recommended to observe the following distances:
- distance before the monitoring head
15 … 20 x D
- distance after the monitoring head
5 x D
