DM08
Before changing the current settings, the cus-
tomer password has to be entered.
Otherwise, the settings only can be watched but
not changed.
The ESC key is used for discarding changes.
Volume flow QV unit:
Using this function, the physical unit, limit val-
ues and the upper-range value of volume flow
can be defined.
For selecting the desired function please use
the key
▲
or
▼
. After choosing the
Volume
flow QV unit
function and pressing the
ENTER key, the following selection field will be
displayed.
Volume flow QV
in [m3/h]
Example:
For changing the parameter please refer to the
description in Section "Selection window / make
a selection".
The following units are available:
Volume units:
m3 / s
m3 / min
m3 / h
l / s
l / min
l / h
USG / s USG / min USG / h
UKG / s UKG / min UKG / h
ft3 / s
MGD
(Mega US Gallons /
day)
Mass units*:
kg / h
t / h
* When selecting a mass unit the liquid density is
certainly required.
8.1.5.1 Scaling the outputs
The measuring variable volume flow rate is
shown by the DM08 as well as an analogue
current output as a pulse output.
The correlation of output and flow rate is not
fixed but it can be defined by the parameters
QV LRV
and
QV URV
(see Fig).
Volume flow lower-range value:
This function allows setting the lower-range
value for volume flow QV LRV which corres-
ponds to the lower-range value for the output
value.
For selecting the desired function please use
the key
▲
or
▼
. After choosing the function
Volume flow lower-range value
and press-
ing Enter, the following selection field will be
displayed:
QV LRV = 0%
+0.000000 m3/h
Example:
The unit for the QV LRV is defined by the func-
tion
Volume flow unit
.
Usually the value for QV LRV is set to 0.0 (fact-
ory default).
Volume flow upper-range value:
This function is intended to set the upper-range
value for volume flow QV URV which corres-
ponds to the upper-range value for the output
value.
