DM08
Low flow cut off:
The
low flow cut off
is a threshold for flow
rate (percentage the upper-range value).
If the volume drops below this value, the dis-
played value and the current outputs will be set
to “ZERO.”
For selecting the desired function please use
the key

or

. After choosing the function
Low
flow cut
and pressing Enter, the following se-
lection field will be displayed.
Low flow cut off
00 %
Example:
The value for low flow cut can be set from 0 to
20 % in 1-percent increments.
Hysteresis for the low flow cut-off:
The value for hysteresis for the low flow cut is
given as a percentage of the upper-range
value. It is the flow rate, the low flow cut has to
be exceeded, to activate the display and the
outputs.
For selecting the desired function please use
the key

or
▼
. After selecting the function
Low
flow cut off hysteresis
and pressing
Enter, the following selection field will be dis-
played.
Low flow cut off
hysteresis 0.0 %
Example:
The hysteresis for the low flow cut can be set
from 0 to 10 % in 1-percent increments.
Note
When the creep rate is exceeded, the
analogue output is set to 0/4 mA and
no pulses are output on the pulse output.
8.1.5 Flow
The FLOW functional class includes functions
that affect lower- and upper-range values and
the processing of the measured flow rates.
