EPD -
Response time
AUTO - OOS Use this parameter to enter the time span for which the criteria for an empty
pipe have to be satisfied without interruption before a notice message or
fault message is generated.
User input:
Fixed point number: 1.0 to 100.0 s
Factory setting:
1.0 s
EPD - Exc.Curr.Max AUTO - OOS Use this parameter 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 in the "Diag. -Act.Sys.Condition"
parameter ( → Page 131) in the same way as the "EPD - Low Value" and
"EPD High Value" parameter.
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.
Ref.Param. - Corr.
Vol.Calculation
AUTO - OOS This parameter is used to set the reference density for calculating the
corrected volume flow.
Options:
CALC. REF. DENSITY
FIX. REF. DENSITY
Factory setting:
CALC. REF. DENSITY
Ref.Param. - Fixed
Ref.Density
AUTO - OOS
! Note!
The entry is not active unless the FIX REF. DENSITY option was selected in
the parameter "Reference Param. - Cor. Volume Calc.".
In this parameter, 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:
1.0000 kg/Nl
Ref.Param. - Fixed
Ref.Density Unit
AUTO - OOS Displays the unit used for the standard density in the calculation of corrected
volume flow.
! Note!
The unit is taken from the parameter "System Unit - Reference Density"
( → Page 129).
