C1.10 Operating Values
Operating values are pre-set according to the application data; value can be adjusted
subsequently, if required.
C1.10.1 Oper. Temperature
Enter value in selected temperature unit.
C1.10.2 Oper. Pressure
Enter value in selected pressure unit.
C1.10.3 Oper. Density
Enter value in selected density unit.
C1.10.4 Min/Max Oper. Dens.
Minimum and maximum operating densities are defined by the nominal diameter and
the operating density as standard. By activating this function, deviating values for the
minimum and maximum operating densities can be defined.
C1.10.4.1 Function
Select: On / Off
If function = "On", min./max. operating density can be defined in C1.10.4.2 and C1.10.4.3
C1.10.4.2 Min. Oper. Density
Enter value for minimum operating density in selected density unit.
C1.10.4.3 Max. Oper. Density
Enter value for maximum operating density in selected density unit.
C1.11 Normal Values
Standard system values are pre-set according to the application data, if applicable.
Standard system can be changed by changing values in C1.11.1 to C1.11.3.
C1.11.1 Norm. Temperature
Enter value in selected temperature unit.
C1.11.2 Norm. Pressure
Enter value in selected pressure unit.
C1.11.3 Norm. Density
Enter value in selected density unit.
C1.12 Heater/Cooler
In net heat measurement applications this functionality monitors "Temp. Source 1"
(C1.6.1) and "Temp. Source 2" (C1.6.2) and triggers a NE 107 status message type C in
case of temperature incongruity.
Select:
- Heater: status message is triggered in case of "Temp. Source 1" < "Temp. Source 2"
- Cooler: status message is triggered in case of "Temp. Source 1" > "Temp. Source 2"
- Don't care: functionality is deactivated

C2 Output
C2.1 Current Output
2-wire current output 4..20 mA (for details refer to
Technical data on page 105)
C2.1.1 Current Out. Meas.
Determination of measurement variable for current output. Measurement variable for
current output is pre-set according to application data.
Select: Volume Flow / Norm. Volume Flow / Mass Flow / Density / Temperature1 /
Pressure / Vortex Frequency / Velocity / Gross Power / Net Power / FAD
The latter three measurement variables are just available if the respective meter type
option was activated.
C2.1.2 0% Range
The set value represents the 4 mA value of the current output. Usually 0% of flow is set
as 4 mA, but it is also possible to assign higher flow values than 4 mA.
C2.1.3 100% Range
The set value represents the 20 mA value of the current output. Usually 100% of flow is
set as 20 mA, but it is also possible to assign lower flow values than 20 mA.
C2.1.4 Lower Ext. Range
Minimum limit of current value. Pre-set value is 4 mA.
Enter: 3.8…4 mA
Condition for value < 4 mA: Measurement value at 4 mA must not be smaller or equal to
0%.
C2.1.5 Upper Ext. Range
Maximum limit of current value. Pre-set value is 20 mA.
Enter: 20…20.5 mA
Condition for value > 20 mA: Measurement value at 20 mA must not be greater or equal
to 100%.
