I USE MODALITY
I1 MECHANICAL CHARACTERISTICS
FOREWORD
The main feature of these nozzles is that they are easy to use.
Two operating modes are available:
1
ASSISTED MODE
Dispense by operating the nozzle lever. To interrupt dispensing man-
ually, release the lever.
2
AUTOMATIC MODE
Use the opening lever lock device for automatic dispensing.
To continue dispensing after automatic stop, the lever must be fully
released before proceeding to operate it again.
To interrupt dispensing in manual mode, press the lever again, there-
by releasing the device, and then release.
ATTENTION
DO NOT USE THE NOZZLE OUTSIDE THE PARAMETERS INDI-
CATED ON THE ”TECHNICAL SPECIFICATIONS” CHART
Dispensing is automatically interrupted thanks to the
shut-off device, which operates when the level of the liquid
reaches the end of the spout.
I2 ELECTRONIC CHARACTERISTICS
ATTENTION
The user can choose between two different operating
modes:
1 - Normal Mode
Normal Mode: Mode with display of Partial and Total dispensed quantities
2 - Flow rate Mode
Flow Rate Mode: Mode with display of Flow Rate, as well as Partial
dispensed quantity.
Note
The meter features a non-volatile memory for storing the dispensing
data, even in the event of a complete power break for long periods. The
measurement electronics and the LCD display are fitted in the top part
of the meter which remains isolated from the fluid-bath measurement
chamber and sealed from the outside by means of a cover.
L MISFILLING (optional)
PREMISE
Refuelling with the nozzle equipped with “magnet switch” is
only possible in combination with the “magnet adapter” , so
misfuelling into tanks is made impossible
OPERATION
The “magnet switch” is a fixed magnetic field within the filler necks of
the nozzle. This opens the magnet switch in the spout, so it is only pos-
sible to dispense from the tank where the magnet adaptor is installed.
ATTENTION
Nozzles equipped with “magnet switch” work only in combi-
nation with the “magnet adapter”. The “magnet adapter” is
an optional to be bought separately.
M PRELIMINARY CHECK

3 Keeping the lever open, make sure the spout is submerged by about
5 cm (2 inches).
4 The nozzle must stop, with a click of the lever.
MEDIUM
CLIP
HIGH CLIP
5 Repeat the same operations with the lever in medium-flow and
maximum-flow position.
Check the correct operation of the stop device as described above.
6 If the nozzle stops during dispensing, check and reduce the flow.
7 If the shut-off device does not begin to operate, check the minimum
flow rate of the system or replace the nozzle.
N INITIAL START UP
FOREWORD
Only start dispensing after making sure that assembly and installa-
tion have been correctly performed.
ATTENTION
It is a good practice to only operate the nozzle lever after
making sure the spout has been properly inserted in the
mouth of the tank to be filled.
NOTE
When using for the first time and every time the nozzle is used, fol-
lowing the connection of the supply hose, gently operate the lever
to enable the air to escape from the circuit, until normal operation
is achieved.
ATTENTION
Check the correct operation of the automatic stop device
once the tank is full.
THE FAULTY OPERATION OF THIS DEVICE COULD CAUSE THE
SPILL OF LIQUIDS THAT ARE HAZARDOUS FOR PEOPLE AND
THE ENVIRONMENT.

sired unit of measurement can be set.
LEGEND
CALIBRATE MEANS PERFORMING ACTIONS ON THE METER KEYS. BELOW IS THE
LEGEND OF THE SYMBOLS USED TO DESCRIBE THE ACTIONS TO BE PERFORMED
O2 BATTERY HOUSING
NOTE
K24 is powered by two 1.5V standard type batteries (size AAA). The
battery housing is easily accessible and is closed by a cover with seal.
Everything is easily removable by taking off the rubber protection
around the nozzle and loosening the screws which secure the cover.
P DAILY USE
FOREWORD
The only operations that need to be done for daily use are partial and/or reset-
table total register resetting. The user should use only the dispensing system of
k24. Occasionally the meter may need to be configured or calibrated. To do so,
please refer to the relevant chapters.
Below are the two typical normal operation displays. One display page shows the partial and reset total
registers. The other shows the partial and general total. Switchover from resettable total to general total
display is automatic and tied to phases and times that are in factory set and cannot be changed.
Note
6 digits are available for Totals, plus two icons x 10 / x100. The incre-
ment sequence is the following:
0.0 -> 99999.9 -> 999999 -> 100000 x 10 -> 999999 x 10 ->100000 x
100 -> 999999 x 100
P1 DISPENSING IN NORMAL MODE
FOREWORD
Normal mode is the standard dispensing. While the count is made, the partial and
resettable total are displayed at the same time (reset total).
WARNING
Should one of the keys be accidentally pressed during dispensing,
this will have no effect.
stand by
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 situa-
tion is called standby and remains stable until the user operates the k24 again.
P1.1
PARTIAL RESET (NORMAL MODE)
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
and, after a few moments, the reset total is replaced by the non reset-
tableTotal.
P1.2
RESETTING THE RESET TOTAL
The reset total resetting operation can only be performed after reset-
ting 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 partia
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.
P2 DISPENSING WITH FLOW RATE MODE DISPLAY
It is possible to dispense fluids, displaying at the same time::
1 the dispensed partial
2 the Flow Rate in [Partial Unit / minute] as shown on the following
display page:
Procedure for entering this mode:
1 wait for the Remote Display to go to Standby, meaning the display screen shows Total only
2 quickly press the CAL key.
3 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.
ATTENTION
The flow rate is measured with reference to
the unit of measurement of the Partial. For
this reason, in case of the unit of measure-
ment of the Partial and Total being dif-
ferent, as in the example shown below, it
should be remembered that the indicated
flow rate relates to the unit of measure-
ment of the partial. In the example shown,
the flow rate is expressed in Qts/min.
The word “Gal” remaining alongside the flow rate refers to the register of the To-
tals (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. If one of the two keys RESET
or CAL is accidentally pressed during the count, this will have no effect.
ATTENTION
Even though in this mode they are not displayed, both the Reset Total
and the General Total (Total) increase. Their value can be checked
after dispensing has terminated, returning to “Normal” mode, by
quickly pressing CAL.
P2.1
PARTIAL RESET (FLOW RATE MODE)
To reset the Partial Register, finish dispensing and wait for the Remote
Display to show a Flow Rate of 0.0 as indicated in the illustration
then quickly press RESET
Q CALIBRATION
Q1 WHY CALIBRATE?
Note
When working in extreme operating or flow conditions, (close to
minimum or maximum acceptable range values), it may be a good
idea to calibrate in the field, in the real conditions in which the
SB32 M has to work..
Q2 DEFINITIONS
CALIBRATION FAC-
TOR OR
“K FACTOR”
Multiplication factor applied by the system to the electrical pulses received, to
transform these into measured fluid units.
FACTORY K
FACTOR
Factory-set default factor. It is equal to 1,000. This calibration factor ensures ut-
most precision in the following operating conditions:
Fluid
water/urea solution or liquid food products Temperature:
20°C
Flow rate: 10 - 30 ltr/min
Even after any changes have been made by the user, the factory k factor can be
restored by means of a simple procedure.
USER K FACTOR:
Customized calibration factor, meaning modified by calibration.

Q4 CALIBRATION MODE
Why calibrate?
1
Display the currently used calibration factor:
2
Return to factory calibration (Factory K Factor) after a previous cali-
bration by the user
3
Change the calibration factor using one of the two previously indi-
cated procedures
FOREWORD
Two procedures are available for changing the Calibration Factor:
1
In-Field Calibration, performed by means of a dispensing operation
2
Direct Calibration, performed by directly changing the calibration factor
In calibration mode, the partial and total dispensed quantities indicated on the display screen take on
different meanings according to the calibration procedure phase.
In calibration mode, the K24 cannot be used for normal dispensing operations.
In “Calibration” mode, the totals are not increased
ATTENTION
The K24 features a non-volatile memory that keeps the data
concerning calibration and total dispensed quantity stored for
an indefinite time, even in the case of a long power break; after
changing the batteries, calibration need not be repeated.
Q4.1
DISPLAY OF CURRENT CALIBRATION

CAL
By pressing the CAL key while the appliance is in
Standby, the display page appears showing the
current calibration factor used. If no calibration
has ever been performed, or the factory setting
has been restored after previous calibrations,
the following display page will appear: The
word “Fact” abbreviation for “factory” shows
that the factory calibration factor is being used
If, on the other hand, calibrations have been
made by the user, the display page will appear
showing the currently used calibration factor ( in
our example 0,998) . The word “user” indicates a
calibration factor set by the user is being used..

Q4.2
IN FIELD CALIBRATION
FOREWORD
This procedure calls for the fluid to be dispensed into a graduated sample con-
tainer in real operating conditions ( flow rate, viscosity, etc.) requiring maximum
precision.
ATTENTION
For correct K24 calibration, it is most important to:
1
When the Factory Factor is confirmed, the old User factor is deleted from the
memory
2
use a precise Sample Container with a capacity of not less than 5 litres, featuring
an accurate graduated indicator.
3
ensure calibration dispensing is done at a constant flow rate equivalent to that of
normal use, until the container is full;
4
Not reduce the flow rate to reach the graduated area of the container during
the final dispensing stage (the correct method during the final stages of sample
container filling consists in making short top-ups at normal operation flow rate) ;
5
after dispensing, wait a few minutes to make sure any air bubbles are eliminated
from the sample container; only read the Real value at the end of this stage, dur
-
ing which the level in the container could drop.
6
Carefully follow the procedure indicated below.

The NEXT calculates the new USER K FACTOR ; this calculation could
require a few seconds, depending on the correction to be made
ATTENTION: If this operation is performed after action (5), without
changing the indicated value, the USER K FACTOR would be the
same as the FACTORY K FACTOR, thus it is ignored.
9
NO OPERATION
At the end of the calculation, the new USER K FACTOR is shown for
a few seconds, after which the restart cycle is repeated to finally
achieve standby condition.
IMPORTANT: From now on, the indicated factor will become the
calibration factor used by the NEXT and will continue to remain
such even after a battery change
10
NO OPERATION
The NEXT stores the new work calibration factor and is ready to
begin dispensing, using the USER K FACTOR that has just been
calculated..
Q4.3
DIRECT MODIFICATION OF K FACTOR
If normal NEXT operation shows a mean percentage error, this can be corrected by applying to the cur-
rently used calibration factor a correction of the same percentage. In this case, the percentage correction
of the USER K FACTOR must be calculated by the operator in the following way
New cal. Factor = Old Cal Factor *
( )
100 - E%
100
Example:
Error percentage found: E% - 0.9 %
CURRENT calibration factor: 1.000
New USER K FACTOR: 1.000 * [(100 – ( - 0.9))/100] = 1.000 * [(100 + 0.9)/100] = 1.009
If the NEXT indicates less than the real dispensed value (negative error) the new calibration factor
must be higher than the old one as shown in the example. The opposite applies if the NEXT shows
more than the real dispensed value (positive error).

The K24 will display the same Reset Total, the same Total and the same Partial indicated before the batter-
ies were changed. After changing the batteries, the meter does not need calibrating again.
CLEANING
Only one operation is necessary to clean the k24.
After removing k24 from the plant where it was built in, any residual
elements can be removed by washing or mechanically-handling.
If this operation does not restore a smooth rotation of the turbine, it
will have to be replaced.
ATTENTION
Do not discard the old batteries in the environment. Refer
to local disposal regulations.
Do not use compressed air onto the turbine in order to
avoid its damage because of an excessive rotation
PERIODICALLY CHECK THE CORRECT OPERATION OF THE
AUTOMATIC STOP DEVICE
IF FITTED, IT IS BEST TO PERIODICALLY CHECK THE FILTER AND
CLEAN IT EVERY 1000 LITRES OF TRANSFER.
PERIODICALLY CHECK THE TIGHTNESS OF THE CONNECTIONS

FOREWORD
THE POSSIBLE CAUSES OF MALFUNCTION ARE MAINLY ATTRIBUT-
ABLE TO THREE FACTORS:
1
NOZZLE DIRTY IN INNER HOLE OF LIP AT END OF SPOUT
2
OPERATING PRESSURE OF LIQUID TO BE DISPENSED BELOW 0.5 bar
OR ABOVE 3.5 bar
3
FLOW RATE TOO LOW OR TOO HIGH
NOTE
CORRECT AND REGULAR MAINTENANCE OF THE NOZZLE AND OF
THE SYSTEM TO WHICH IT IS CONNECTED PREVENTS MALFUNC-
TIONS AND POSSIBLE ACCIDENTAL SPILLS OF HAZARDOUS LIQUIDS.
