Installation

No special measures such as supports 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.
