Installation

No special measures such as supports etc. are necessary. External forces are absorbed by the
construction of the device.
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.
