Selection of unit for mass flow.
Refer to Table 3: Units for the mass flow on page 77.
The selection applies to the display of the current mass flow, and for the parameters related to mass flow such
as QmMax and Qm DN.
Max
Select the unit for the mass totalizer.
Refer to Table 4: Units for the mass totalizer on page 77.
Selection of unit for volume flow.
Refer to Table 2: Units for the volume flow on page 77.
The selection applies to the display of the current volume flow and for the parameters related to volume flow
such as QvMax and Qv DN.
Max
Selection of unit for the volume totalizers.
Refer to Table 5: Units for the volume totalizer on page 77.
Selection of the unit for external process variables.
The transmitter can show two external process variables in the display. The process variables can be
transferred from the fieldbus master to the transmitter via the HART, Modbus or PROFIBUS DP protocol. You
can configure the display through the 'Display' menu.
Enter the name for the user-defined mass flow unit.
Enter the factor for a user-defined mass flow unit. The factor relates to the flow per liter.
Enter the name of the user-defined totalizer unit for mass flow.
Enter the factor for a user-defined mass flow unit. The factor relates to the flow per liter.
Enter the name for the user-defined volume flow unit.
Enter the factor for a user-defined volume flow unit. The factor relates to the flow per liter.
Enter the name for the user-defined volume flow unit.
Enter the factor for a user-defined volume flow unit.
The factor relates to the flow per gallon.
Set the switching threshold (0 to 10 %) for the low flow cut-off.
If the flow rate is below the switching threshold, there is no flow measurement. The setting of 0 % deactivates
the low flow cut-off.
Default setting: 1.0 %
Set the hysteresis (0 to 50 %) for the low flow cut-off as it is defined in the parameter 'Low Flow Cut Off'.
Default setting: 20 %
