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.
