Installation

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.
