Mounting location
A0028772
To prevent measuring errors arising from accumulation of gas bubbles in the measuring tube, avoid
the following mounting locations in the pipe:
• Highest point of a pipeline.
• Directly upstream of a free pipe outlet in a down pipe.
Installation in down pipes
However, the following installation suggestion allows for 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.

Orientation
The direction of the arrow on the sensor nameplate helps you to install the sensor according to the
flow direction (direction of medium flow through the piping).
