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 dia meters
(D) before the monitoring head without any bends and changes in pipe diameter if the velocity profile
is only slightly disturbed. For heavily disturbed velocity profiles, above all for a superimposed swirl-
flow, there should be a distance of 20 ... 50 pipe diameters (D) before the monitoring head in order
to eliminate high deviations of the measured values.
It is generally recommend to observe the following distances (see fig . 13):
• distance before the monitoring head without any bends and changes in pipe diameter:
15 ... 20 x D
• distance after the monitoring head without any bends and changes in pipe diameter:
5 x D
