Installation in pipelines with larger nominal widths
Determine the resulting pressure loss when using reducers (1):
1.
Determine the diameter ratio d/D
2.
Refer to the flow nomograph for the flow velocity (adjacent figure).
3.
Read the pressure loss on the Y-axis in the flow nomogram.
(1) Flange transition piece
(d) Inner diameter of the flowmeter
(D) Inner diameter of the pipeline
