5.4.2 "Pipe/fluid settings" menu
In "simple configuration" mode, access to the settings is restricted to the following sections:
1) Number of chords
Enter the number of chords used for your application.
2) Flow unit (unit Q)
Enter the flow unit to be displayed.
3) Flow graph
The flow graph is a screen in Measurement mode. It displays the changes
in a specific magnitude in the form of a curve (see the possible
dimensions below).
Enter the minimum and maximum limits of the dimension associated with
the flow graph. These limits mark the boundaries of the vertical display of
the flow graph.
The flow graph Period setting is used to define the time interval between
two successive points. The possible values are: 1 s, 5 s, 10 s, 30 s, 1 min,
2 mins, 5 mins, 10 mins, 15 mins, 30 mins, 1 hr, 2 hrs, 6 hrs, 12 hrs and
24 hrs.
Example: If the period of the flow graph is 1 min, each point of the curve represents the average value of
the dimension associated with the flow graph over 1 min and the whole screen shows the evolution of the
flow over the last 144 minutes.
4) Type of fluid
In simple configuration mode, the fluid must be water at ambient temperature (cannot be modified).
5) Chord settings
The settings to be entered for the definition of a chord are as follows:
 the reference of the probes used,
 the length (in metres) between the faces of the two probes,
 the projected length (axis diameter) with regard to the axis of the channel or the river,
 the height compared to H0.
