3. Specify height and diameter of the dry weather flume.
4. Use the 3D-Preview to verify whether dimensions are specified correctly.
U-Profile
The U-profile is composed from a bottom semicircle and vertical walls. The semicircle radius
here is ½ the channel width and is entered automatically by the system.
Profiles with radii larger than ½x channel width should be created as free profiles.
Trapezoid
This selection allows setting the parameters for symmetric channels featuring a horizontal
bottom and sloped walls. Parameters of symmetric channels with a horizontal bottom, sloped
walls and featuring vertical walls at the top can be set in this menu too.
Right as with rectangular profiles, a dry weather flume can be added as extra option.

Ü
Proceed as described in the rectangle with dry weather flume section on page 83.
Channel
Sound Expert Knowledge required
Setting the parameters for a water bed requires sound knowledge and comprehensive
experience on the operation of the NivuFlow Mobile as well as about hydrologic ambient
conditions.
We recommend letting the NIVUS commissioning service or a company authorised by
NIVUS do the programming works.
In this profile you define the reference point/zero point yourself. Mostly, the maximum level or
the water surface on one bank or channel side is determined as zero point. By performing local
measurements on site you can save the profile of a certain section of the water body in the
transmitter here.
Â
Ü
Enter the freely defined measuring section into the table one after the other.
Symmetric profile using height-width (Heigth-Width (sym.))
This menu can be used to set any kind of symmetric profiles.
Selecting the button >Table< indicates a table of values where a maximum of 32 breakpoint
pairs (channel height/channel width) can be entered. The system calculates these values
automatically and saves them as symmetric profile in the internal memory.
