Installation
Mounting location
Entrained air or gas bubbles in the measuring tube can result in an increase in measuring errors.
Therefore, avoid
the following mounting locations in the pipe installation:
• Highest point of a pipeline. Risk of air accumulating.
• Directly upstream of a free pipe outlet in a vertical pipeline.

Mounting location
Installation in down pipes
Notwithstanding the above, the installation proposal below permits installation in an open vertical
pipeline. Pipe restrictions or the use of an orifice with a smaller cross-section than the nominal
diameter prevent the sensor running empty while measurement is in progress.
