Mounting With Pipe Vibration - ABB FSM4000 Manual

FSM4000 ELECTROMAGNETIC FLOWMETER | DS/FSM4000-EN REV. L
Free inlet or outlet
Figure 6: Free inflow and outflow
A 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.
B For free inflow/outflow, provide an invert to make sure
that the piping is always full
Mounting with heavily contaminated measuring media
Figure 7: 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 8: 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.
Sensor insulation
1 Insulation
Figure 9: Insulation of the flowmeter sensor
In the high temperature design, the flowmeter sensor can be
completely thermally insulated. After the unit is installed, the
piping and sensor must be insulated in accordance with the
figure.
