28.1.6 Channel Profiles
The NivuFlow Mobile with clamp-on measurement permits to select between "Pipe" and "Rec-
tangular". "Pipe" is circular, not elliptic.
The selected profile is indicated as a graph in the preview field. The graphic representation,
however, does not coincide with the dimensions (in relation) specified. There is
no visual
control
available.

The dimensional values are entered as soon as the profile has been chosen. The unit is
set to meter [m] per default. This can be changed in the >System< / >Region Settings< /
>Units< / >Level< menu (Fig. 28-4).

Entering the channel dimensions
For
pipes
it is sufficient to enter two values to specify the pipe dimensions:
• Pipe circumference or inside/outside diameter
• Wall thickness
Entering inside diameter and the wall thickness causes the transmitter to add outside diameter
and pipe circumference automatically. The same applies once circumference and wall thick-
ness are entered. The transmitter adds the missing parameters.
For
pipes with inner lining
it is necessary to additionally specify the thickness of the lining
material. The transmitter includes the material thickness with the calculation and uses it to
compute the correct inside diameter.
For
rectangular profiles
width, height and wall thickness are required. If the channel is
equipped with a lining the thickness of the lining needs to be specified too.
