5 . . .Installation
Free inlet or outlet
Mounting with heavily contaminated measuring media
Mounting with pipe vibration
For strongly contaminated measuring media, a bypass line in
accordance with the figure is recommended so that operation
of the system can continue to run without interruption during
mechanical cleaning.
If pipe vibration occurs, it needs to be damped using
damping devices. The damping devices must be installed
outside the support section and outside of the piping section
between the turn-off devices. Avoid connecting damping
devices directly to the flowmeter sensor.

For a free outflow, do not install flowmeter at the
highest point of the piping or on its outflow side,
since the measuring tube may run empty, creating
air bubbles.
For free inflow/outflow, provide an invert to make
sure that the piping is always full.
