3.2.1.2 Duct/pipe diameter < 0.5 m
The activities are generally the same as those for larger diameters. The difference with
small diameters is that installing the flanges and sender/receiver units can have a greater
impact on the flow characteristics. To minimize this impact, therefore, the flange pipes
should not be inserted in the pipeline, but rather mounted and welded on the outside.
There are two installation options (see Fig. 3.11):
• On two sides
• On one side, using the sound reflection at the opposite inside wall.
This solution can be used with very small ducts to increase the measuring distance, or if
access is only possible from one side.
