Qm Max
Qm Max set the upper range value for the mass flow.
Qm Min
Set the lower range value for the mass flow.
Qv@ Max
Set the upper range value for standard volume flow.
Qv@ Min
Set the lower range value for standard volume flow.
Damping Q
Select the damping for fl
ow measurement.
The value set here relates to 1 τ (Tau). The value refers to the response time for a step flowrate change. It affects the
instantaneous value in the display and at the current output.
Default setting: 0.2 seconds
Low Flow Cut Off
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
%
LowFlow Hysteresis
Set the hysteresi
s (0 to 50 %) for the low flow cut-off as it is defined in the parameter ‘Low Flow Cut Off’.
Default setting: 20 %
