4.7 INSTRUCTIONS FOR DIAMETER REDUCTION
In the case of diameter reduction, please refer to the indications shown in the figure below.
The diameter reduction introduces a pressure drop in the system. Pay attention, especially when the
flow rates are high and if the section reduction is applied simultaneously with the use of reduced
section meters.
In the case of low pressures, the section reduction could also lead to cavitation formation, especially
if the meter has a reduced section; this condition must be absolutely avoided.
