danger
risk of injury due to high pressure in the installation.
• Stop the circulation of fluid, cut off the pressure and drain the pipe before loosening the process connections.
risk of injury due to the nature of the fluid.
• Respect the prevailing regulations on accident prevention and safety relating to the use of aggressive fluids.
The 8045 flowmeter has to be inserted into an S020 fitting mounted on a pipe.

Choose an S020 fitting appropriate to the velocity of the fluid inside the pipe: refer to the graphs below:

Example
Flow rate
Fluid 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 appro-
priate pipe diameter, DN40 (or DN50 for
the asterisked fittings).
* For the fittings:
• with external thread connections acc. to
SMS 1145,
• with welding end connections acc. to
SMS 3008, BS 4825 / ASME BPE or
DIN 11850 Rg 2,
• with Clamp connections acc.
to SMS 3017 / ISO 2852,
BS 4825 / ASME BPE or DIN 32676.
