Function description
BASIC FUNCTION o PROCESS PARAMETER o PRESSURE CORRECTION
PRESSURE MODE
(6500)
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 83,
BA 059D/06/en, Accuracy Chapter).
Options:
OFF
MEASURED
This selection is only available if a current input has been selected in the function
ASSIGN CURRENT INPUT (5200) PRESSURE.
The actual measured process pressure is read in for pressure correction via the current
input.
FIX
A fixed process pressure for pressure correction is specified (see function PRESSURE
(6501)).
Factory setting:
OFF
PRESSURE
(6501)
! Note!
This function is only available if FIX was selected in the PRESSURE MODE function
(6500).
Use this function to enter the value for the process pressure which should be used during
pressure correction.
User input:
7-digit floating-point number
Factory setting:
0 bar g
! Note!
The appropriate unit is taken from the function group SYSTEM UNITS (see page 17).
