4.3 Measurements to be taken on site
4.3.1 Topography of the site
For future configuration of your Uf 831, the following points should be measured:
Geometry of banks upstream, downstream and level with the measuring point,
Pile (or probe support) position and the position of the ultrasonic probes,
Floor profile (bathymetry),
Water level on the water level gauge (day, date and time of operation).
4.3.2 Determining the different levels in relation to the stream
For future configuration of your Uf 831, the following measurements need to be taken on site in relation to
the water level:
The level probe(s),
The velocity measurement chords (ultrasonic probes).
4.4 Analysing and processing data measured on site
In preparation for configuring your meter, produce the site plan and the plan of the different heights using
the data collected.
Follow the 5 steps below to produce your 2 plans.
1.
Trace the position:
o
Of the probe supports
o
Of the water level gauge
o
Of the banks
2.
Work out the main axis of flow
3.
Project the position of the probes onto this axis
4.
On the plan, measure:
o
The distance between probes "L"
o
The axis diameter
5.
Produce the plan of the different heights:
o
Of the water level gauge
o
Of the velocity measurement chords (ultrasonic probes)
o
Of the level sensors
