Figure 18: 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.
Installation in piping with larger nominal diameter

Reducer
Figure 19: Using reducers
Determine the resulting pressure loss when using reducers:
1. Determine diameter ratios d/D.
2. .Determine the flow velocity based on the flow rate
nomogram (Figure 20).
3. Read the pressure loss on the Y-axis in Figure 20.
