The above tables show the effect that an increase of temperature or change of material have
on the maximum working pressure of the flange. The values are independent of nominal size.
For intermediate temperatures use value from nearest higher temperature.
Example
For a PN 16 flange in 2C2 (316) material at 80 degrees the maximum working pressure should
be taken as 12.5 bar.

The sensor must be mounted between two
flanges. Gaskets are only necessary when the
flowmeter is installed with earthing flanges as
the liner is used in place of gaskets.
When measuring abrasive liquids the use of
flowmeter inlet protection may be necessary.
Here type C earthing flanges are used.
