Flow unit (048)
Options
Select volume flow unit.
When a new flow unit is selected, all flow-specific parameters are converted and
displayed with the new unit within a flow type. When the flow type is changed,
conversion is not possible.
Prerequisite:

Max. flow (009)
Entry
Enter maximum flow of primary element.
See also layout sheet of primary element. The maximum flow is assigned to the
maximum pressure which you enter via "Max. pressure flow (010)".
Factory setting:
100.0
Max. pressure flow (010)
Entry
Enter maximum pressure of primary element.
See layout sheet of primary element. This value is assigned to the maximum
flow value (see "Max. flow (009)").
Factory setting:
Upper-range limit (URL) of the sensor
Set low-flow cut-off (049)
Entry
Enter switch-on point of the flow-flow cut-off.
The hysteresis between the switch-on point and the switch-off point is always 1 %
of the maximum flow value.
Input range:
Switch-off point: 0 to 50% of end flow value ("Max. flow (009)").
A0025191
Factory setting:
5 % (of the maximum flow value)
