29 Example 2: Measurement in open waters
29.1 In General
The second measurement example is performed in an open water body.
The used transit time sensors are NIVUS hemispheres since they are very well suited for
slanted installation on river banks. The related banks should be stable and should not tend to
changes.
Measurement places featuring a defined and consistent flow cross section provide the best
conditions.
In order to set measurement place parameters the basic settings below are required at
least:
• Number of paths and path arrangement
• Measured medium
• Shape and dimensions of measurement place
• Sensors used and respective positions
Observe the preparatory measures and other information for the measuring
section as provided in the “Installation Instruction Transit Time Sensors”.
Diving works possibly required
Observe that installing sensors in open waters might require diving works. Diving works in
turn require observing particular regulations on safety at work. Prepare such activities very
carefully.
Prior to planning diving activities make sure to obtain any necessary permits from the
responsible authorities.
