Flange connection:
• DN 15 (½"): ±20 % of the internal diameter
• DN 25 (1"): ±15 % of the internal diameter
• DN 40 (1½"): ±12 % of the internal diameter
• DN 侒 50 (2"): ±10 % of the internal diameter
If the standard internal diameter of the ordered process connection differs from the
internal diameter of the mating pipe, an additional measuring uncertainty of approx. 2 %
o.r. must be expected.
Example
Influence of the diameter mismatch without using the correction function:
• Mating pipe DN 100 (4"), Schedule 80
• Device flange DN 100 (4"), Schedule 40
• This installation position results in a diameter mismatch of 5 mm (0.2 in). If the
correction function is not used, an additional measuring uncertainty of approx. 2 % o.r.
must be expected.
• If the basic conditions are met and the feature is enabled, the additional measuring
uncertainty is 1 % o.r.
