Note!
Quick Setup automatically deactivates the function EMPTY PIPE DETECTION (6420) so that the
instrument can measure flow at low gas pressures.
Corrected volume measurement with gas:
Proceed as follows if the corrected volume flow (e.g. in Nm
3
/h) should be displayed and output
instead of the mass flow (e.g. in kg/h).
1.
Select the “Commissioning” Quick Setup menu via the function matrix
2.
Under “Defaults”, select the “Corrected volume flow” system unit and configure the following
functions as follows:
3.
Exit the “Commissioning” Quick Setup menu. Then return to the HOME position.

ASSIGN
LOW FLOW CUTOFF
On account of the low mass flow involved when gas flows are mea-
sured, it is advisable not use a low flow cutoff.
Setting: OFF
6402
LOW FLOW CUTOFF
ON-VALUE
If the ASSIGN LOW FLOW CUTOFF function was not set to “OFF”,
the following applies:
Setting: 0.0000 [unit]
User input: Flow rates for gas measurements are low, so the value for
the switch-on point (= low flow cutoff) must be correspondingly low.
6403
LOW FLOW CUTOFF
OFF-VALUE
If the ASSIGN LOW FLOW CUTOFF function was not set to “OFF”,
the following applies:
Setting: 50%
User input: Enter the switch-off point as a positive hysteresis in %,
referenced to the switch-on point.
