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 veloc-
ity (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
Nomograph for pressure loss calculations
For flange transition piece with α/2 = 8°
(V) Flow velocity [m/s]
(∆p) Pressure loss [mbar]
