The content of the tables has been compiled to help the user. The accuracy of the given data depends on the composition,
the temperature and the manufacturing process of the respective material. We do not accept liability for possible
inaccuracies.
Table 1 -
Pipe parameters stored
in FLUXUS
The following table shows the most important
parameters for pipe materials and/or linings, which are
already pre-programmed in the instrument. On request,
we can optimise the material list or extend it with new
materials, should this be required.

Table 3 - Typical roughness coefficients for pipes
For your convenience, we have already pre-programmed common roughness coefficients for pipe materials.
The data are based upon experience with measurements performed with these pipe materials:
Pipewall material
Absolute roughness [
µ
m]
Drawn pipes of non-ferrous metal, glass, plastics and light
metal 0 ... 1.5
Drawn steel pipes 10 ... 50
•
fine-planed, polished surface up to 10
•
planed surface 10 ... 40
•
rough-planed surface 50 ... 00
Welded steel pipes, new 50 ... 100
•
long usage, cleaned 150 ... 200
•
lightly and evenly rusted up to 400
•
heavily encrusted up to 3,000
Cast iron pipes
•
bitumen lining 120
•
new, without lining 250 ... 1000
•
rusted 1000 ... 1500
•
encrusted 1500 ... 3000
Table 4 - Media parameters
The instrument is already pre-programmed with the most frequently used media
parameters. On request, we can optimise this list or extend it with new media.
