Function group LIMIT VALUES
You can specify the limit values for measured variables in this function group. If the deviation of a
verification step (see OPERATION, P. 38) lies within the configured limit values the result is
PASSED; if it lies outside of this range the result is FAILED. For quick and unambiguous
identification, the FAILED results are shown in white with a black background on the display.
Function description
FUNCTION  VERIFICATION  LIMIT VALUES
BASIC FLOW LIM. Use this function to specify the basis for calculating the permitted deviation of the
individual measuring points.
A higher limit is assigned to low flow velocities while higher flow velocities are closer to
the lower limit (similar to the error curve of the measuring device).
User input:
0.30 to 10.00 % (for Promass 80, 83)
0.60 to 10.00 % (for Promass 40)
Factory setting:
0.50 % (for Promass 80, 83)
0.60 % (for Promass 40)
CALCULATED FLOW
LIMITS
Use this function to read the value calculated by Fieldcheck during verification to
establish whether the result is PASSED or FAILED. A separate value is given for each of
measuring points MP1, MP2, MP3 and MP4.
DEVIATION DENSITY User input:
0.50 to 10.00 %
Factory setting:
0.5 %
