Description Additional parameters required Parameter setting
Liquid Mass (volume
adjustment) / NL3
Fluid mass flow, based on
reference density and volume
expansion coefficient in the
normal condition
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.
Reference density in the normal condition Device Setup / Plant/Customized /
Compensation Setting -> Ref. Density
Liquid Power / NL44) Energy flow of the liquid medium,
such as brine or condensate
Heat capacity Device Setup / Plant/Customized /
Compensation Setting -> Heat Capacity
Measuring medium temperature at the
inflow
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
Measuring medium temperature at the
outflow
3), 5)
Via analog input:
Input/Output / Field Input / Analog In Value ->
Temperature
Via HART input:
Input/Output / Field Input / Hart In Value ->
Temperature
Default setting for the temperature:
Device Setup / Plant/Customized /
Compensation Setting -> Preset Ext.Temp
Gas Act. Volume / NG1

1) The highest priority of the device is to record the operating temperature.
3) The connection via the analog input or HART input is described in the chapter titled „Electrical connections“ on page 21.
4) In order to implement the "Liquid Power" mode, as a precondition the required parameters from one of the NL3 modes must be available. See chapter „Measuring the
energy of liquids“ on page 37.
5) The highest priority of the device is to record the temperature via the analog input, as long as the analog input is activated as a temperature input. If the analog input is
not available as a temperature input, the system attempts to record the temperature via the HART input. If both the analog input and the HART input are deactivated
as a temperature input, the system uses the default density value.
