Example
Flow rate
Flow velocity
Example:
• Specification: if the nominal flow
rate is 10 m 3 /h, the ideal flow
velocity is between 2 and 3 m/s.
• Solution: intersection between
flow rate and flow velocity in the
graph gives the appropriate pipe
diameter, DN40 (or DN50 for
the asterisked fittings).
1) The device cannot be installed
onto the following DN20 fittings:
* For the fittings:
• with external threads acc. to
SMS 1145.
• with weld ends
acc. to SMS 3008,
BS 4825 / ASME BPE or
DIN 11850 Rg2.
• Clamp acc. to
SMS 3017 / ISO 2852,
BS 4825 / ASME BPE or
DIN 32676.
