6.6 Operating mode
The parameters for the different operating modes are described in the following table.
Operating mode /
(order code)
Designation Additional parameters required Parameter setting
Liquid Volume / NL1 Operating volume flow
(for liquid measuring medium)
— —
Liquid Volume
(temperature
compensated) / NL2
Standard volume flow
(for liquid measuring medium)
Measuring medium temperature
1)
With internal temperature sensor.
No information required, the measured value
from the temperature sensor is used.
Default setting for the temperature value:
Device Setup / Plant/Customized /
Compensation Setting -> Preset Int.Temp
Reference temperature in the normal
condition
Device Setup / Plant/Customized /
Compensation Setting -> Ref. Temperature
Volume expansion coefficient Device Setup / Plant/Customized /
Compensation Setting -> Volume Exp.Coef.
Liquid Mass (no
correction) / NL3
Liquid mass flow, based on direct
determination of the operating
density via analog input, HART
input or default setting.
(for liquid measuring medium)
Operating density
2) 3)
Via analog input:
Input/Output / Field Input / Analog In Value ->
Density
Via HART input:
Input/Output / Field Input / HART In Value ->
Density
Default setting for the density:
Device Setup / Plant/Customized /
Compensation Setting -> Preset Density
Liquid Mass (density
adjustment) / NL3
Mass flow rate, based on the
density under reference
conditions and density expansion
coefficient in the normal
condition.
(for liquid measuring medium)
Measuring medium temperature
1)
With internal temperature sensor.
No information required, the measured value
from the temperature sensor is used.
Default setting for the temperature value:
Device Setup / Plant/Customized /
Compensation Setting -> Preset Int.Temp
Reference temperature in the normal
condition
Device Setup / Plant/Customized /
Compensation Setting -> Ref. Temperature
Density expansion coefficient Device Setup / Plant/Customized /
Compensation Setting -> Density Exp.Coef.
Density under reference conditions in the
normal condition
Device Setup / Plant/Customized /
Compensation Setting -> Ref. Density
1) The highest priority of the device is to record the operating temperature.
2) The highest priority of the device is to record the density via the analog input, as long as the analog input is activated as a density input. If the analog input is not
available as a density input, the system attempts to record the density via the HART input. If both the analog input and the HART input are deactivated as a density
input, the system uses the default density value.
3) The connection via the analog input or HART input is described in the chapter titled "Electrical connections" on page 29.
