14 Group PROCESS PARAMETER Device Functions Proline Promass 80
52 Endress+Hauser
MEASURE FLUID In this function the actual density of the fluid is measured for the density adjustment.
Options:
CANCEL
START
DENSITY ADJUST With this function a density adjustment can be carried out on site.
The density set value will thus be recalculated and stored. This ensures that the values
dependent on density calculations (e.g. volume flow) are as accurate as possible.
" Caution!
Before carrying out a density adjustment, please refer to BA 057D/06/en
“Promass 80 Operating Instructions” where a detailed description of the density
adjustment is given.
! Note!
The density adjustment can be executed if:
• The sensor does not accurately measure the density which the operator expects based
on laboratory trials.
• The characteristics of the fluid are outside the measuring points set at the factory or
reference conditions under which the flowmeter has been calibrated.
• The plant is used solely for measuring a fluid whose density is to be determined very
accurately under constant conditions.
Options:
CANCEL
DENSITY ADJUST
Factory setting:
CANCEL
RESTORE ORIGINAL With this function the original density coefficient determined at the factory are restored.
Options:
NO YES
Factory setting:
NO
PRESSURE MODE Use this function to configure an automatic pressure correction. In this way, the effect of
a pressure deviation between the calibration and process pressures on the measured error
for mass flow is compensated for, (see also Operating Instructions "Proline Promass 80",
BA 057D/06/en/, Accuracy Chapter).
Options:
OFF
PRESSUREFIX (A fixed process pressure for pressure correction is specified)
Factory setting:
OFF
