4.6.7 Installation in the vicinity of pumps
•
For flowmeter primaries that are installed near pumps or other
vibration-causing fixtures, the use of mechanical vibration control
components is mandatory.

4.6.8 Installation in larger size pipelines
Determine the resulting pressure loss when using reduction
pieces (1):
1.
Calculate the diameter ratio d/D.
2.
Determine the flow velocity based on the flow range nomograph
(Fig. 24).
3.
Read the pressure drop on the Y-axis in Fig. 24.
