After installing the meter and completing the electrical connec-
tions, the meter parameters must be compared with the values of
the calibration certificate or test certificate. Example:
• Path lengths
• Axial distances
• Limit values
They are listed in an alphabetical order of their corresponding
matrix coordinates and can be found using the operating display.
As an alternative, they can be read out of the USE09 directly us-
ing the operating software RMGView
The functions can be checked as soon as the meter is exposed
to pressure.
For this purpose, the content of the valid measurements (in %)
are checked in the coordinates L-6 to Q-6. They should be 100%
at zero flow and should also not fall below 70% under difficult flow
conditions, for example, with high flow rates.
If the operating pressure is not reached, a functional check is only
possible to a limited extent.
In this case, contact RMG services.
