Eexample volumetric flow monitoring
Factory setting
Measuring range scaled
MEW = final value of the measuring range
In the set measuring range the output signal is between 4 and 20 mA�
It is also indicated:
Volumetric flow above the measuring range: output signal > 20 mA�
4.5 Customer-specific calibration
This calibration changes the slope of the curve of measured values for volumetric
flow� It influences the display and the outputs�
A
operating value for display and
output signals
Q
volumetric flow
MEW final value of the measuring
range
V0
curve of measured values
without calibration
V1,
V2
curve of measured values
after calibration
The change in the increase is indicated in percent� 100% corresponds to the fac-
tory calibration� It can be reset (→ 9�4�5)�
