It can be specified which materials will be displayed in the scroll list (see section 16.5).
If Other Material is selected, the sound speed must be entered.
For the sound speed of some materials see annex C.1.
11.1.5 Pipe Roughness
The flow profile of the medium is influenced by the roughness of the inner pipe wall. The
roughness will be used for the calculation of the profile correction factor. As, in most cas-
es, the pipe roughness can not be exactly determined, it has to be estimated.
For the roughness of some materials see annex C.2.
If the pipe has an inner lining, select yes. Press ENTER.

within the inner pipe diameter range of the connected transducers,
an error message will be displayed.
It is possible to change the lower limit of the inner pipe diameter for a
given transducer type (see section 13.8).
