Free Inlet Or Outlet; Mounting With Heavily Contaminated Measuring Media; Mounting With Pipe Vibration - ABB ProcessMaster FEP630 Series Operating Instruction

FEP630, FEH630 ELECTROMAGNETIC FLOWMETER | OI/FEP630/FEH630-EN REV. D

Free inlet or outlet

Figure 17: Free inflow and outflow
For a free outflow, do not install flowmeter at the highest
A
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
B
the piping is always full

Mounting with heavily contaminated measuring media

Figure 18: Bypass line
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.

Mounting with pipe vibration

1 Pump
2 Damping device
Figure 19: Vibration damping
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.
