Comprehensive expert knowledge is required to properly utilise these parame-
ters. We therefore recommend the NIVUS commissioning service or a thor-
ough device training.

Manning Strickler
The theoretical discharge curve is calculated using the settings under >Dimen-
sions<, >Slope< and >Roughness<.
This function may be combined with the automatic mode. The theoretical set-
tings within the flow velocity monitoring area (see Fig. 9-68, No. 4) will be veri-
fied using this method.

Slope
Enter the slope at measurement point in %
Strickler -coefficient
Enter the Manning - Strickler coefficient
Please see Table „Manning - Strickler Coefficients“ in chapter 14 for more
information.
Manual
Enter the current level and the current flow velocity (measured using a refer-
ence) directly. The theoretical discharge curve is calculated from these values.
This function may be combined with the automatic mode. The theoretical set-
tings within the flow velocity monitoring area (see Fig. 9-68, No. 4) will be veri-
fied using this method.
