7.2.3 Function group REFERENCE PARAMETER
EPD EXCITATION
CURRENT MAXIMUM
(6426)
Use this function to activate the empty pipe detection (EPD).
In the event of inhomogeneous fluids or air bubbles, the excitation current of the
measuring pipes increases. If the excitation current set in this function is exceeded,
error message #700 is output similar to the functions "EPD VALUE LOW (6423)" and
"EPD VALUE HIGH (6424)".
User input:
5-digit floating-point number
Factory setting:
100.00 mA (deactivated)
! Note!
The function is not activated until a value under 100 mA is input. Entering the value
100 mA deactivates the function.

CORRECTED VOLUME
CALCULATION
(6460)
This function is used to set the reference density for calculating the corrected volume
flow.
Options:
FIXED REFERENCE DENSITY
CALCULATED REFERENCE DENSITY
Factory setting:
CALCULATED REFERENCE DENSITY
FIXED REFERENCE
DENSITY
(6461)
! Note!
This function is not available unless the FIXED REFERENCE DENSITY setting was
selected in the CORRECTED VOLUME CALCULATION function (6460).
In this function, a fixed value for the reference density can be entered, with which the
corrected volume flow or corrected volume is calculated.
User input:
5-digit floating-point number
Factory setting:
