Flow Meter
Dispensing in Normal Mode
Normal mode is the standard
dispensing. While the count is
made, the partial and resettable total
are displayed at the same time
(reset total).
Should one of the keys be
accidentally pressed during
dispensing, this will have no effect.
A few seconds after dispensing has ended, on the
lower register, the display switches from resettable
total to general total: the word reset above the word
total disappears, and the reset total is replaced by the
general total. This situation is called standby and
remains stable until the user operates the 8424 again.
Partial Reset
The partial register can be reset by
pressing the reset key when the meter
is in standby, meaning when the
display screen shows the word
"TOTAL".
After pressing the reset key, during
reset, the display screen first of all
shows all the lit-up digits and then all
the digits that are not lit up.
At the end of the process, a display
page is first of all shown with the reset
partial and the reset total.
After a few moments, the reset total is replaced by the
non resettable Total.
Resetting the Reset Total
The reset total resetting operation can only be
performed after resetting the partial register. The reset
total can in fact be reset by pressing the reset key at length
while the display screen shows reset total as on the
following display page:
Schematically, the steps to be taken are:
1. Wait for the display to show normal
standby display page (with total
only displayed)
2. Press the reset key quickly

3. The meter starts to reset the partial
4. While the display page showing the
reset total is displayed Press the
reset key again for at least 1 second.
5. The display screen again shows all
the segments of the display
followed by all the switched-off segments and finally
shows the display page where the reset Reset Total is
shown.
Dispensing with Flow Rate Mode display
It is possible to dispense fluids,
displaying at the same time:
• The dispensed partial
• The Flow Rate in [Partial Unit/minute]
• As shown on the following display page:
Procedure for entering this mode:
• Wait for the Remote Display to go to Standby,
meaning the display screen shows Total only
• Quickly press the CAL key.
• Start dispensing
The flow rate is updated every 0.7 seconds.
Consequently, the display could be relatively unstable at
lower flow rates. The higher the flow rate, the more stable
the displayed value.
WARNING
The flow rate is measured with reference to the
unit of measurement of the Partial. For this reason,
in case the unit of measurement of the Partial
and Total being different, as in the example shown
below, it should be remembered that the indicated
flow rate relates to the unit of measurement
partial. In the example shown, the flow rate is
expressed in Qts/min.
"Gal" remaining alongside the flow
rate refers to the register of the
Totals (Reset or NON Reset) which
are again displayed when exiting
from the flow rate reading mode.
To return to "Normal" mode, press the CAL key again.
