F INSTALLATION
FOREWORD
K24 features a threaded, perpendicular inlet and outlet (1” BSP male
and female that can be combined together). It has been designed to
be easily installed in any position: xed in-line or mobile on a dispensing nozzle. In order to improve the life of the turbine, it is recommended to t a strainer before the meter itself
ATTENTION An F/F coupling, complete with its gasket, is supplied
for installations on male couplings. Always screw the
side with gasket on K24.
It is up to the installer to use another gasket on the
other side of the coupling.
The gasket used has the following characteristics: at
seal id=24, od=35.5 , thick=2 Material: NBR 70 SH
For installations on system, position K24 so that the
battery housing can be easily reached.
G DAILY USE
FOREWORD
The only operations that need to be done for daily use are partial and/
or resettable total register resetting. The user should use only the dispensing system of k24. Occasionally the meter may need to be con-
gured 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.
NOTA 6 digits are available for Totals, plus two icons x 10 /
x100. The increment sequence is the following:
0.0 -> 99999.9 -> 999999 -> 100000 x 10 -> 999999 x
10 ->100000 x 100 -> 999999 x 100
G.1 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 eect.
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 situation is called standby and remains stable until the user
operates the k24 again.
G.1.1 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
rst 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 rst of all shown
with the reset partial and the reset total
and, after a few moments, the reset total is replaced by the
non resettableTotal.
G.1.2 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-o segments and
nally shows the display page where the reset Reset
Total is shown.
C.2 DISPENSING WITH FLOW RATE MODE DISPLAY
It is possible to dispense uids, 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 ow rate is updated every 0.7 seconds. Consequently, the display could be relatively
unstable at lower ow rates. The higher the ow rate, the more stable the displayed
value.
IMPORTANT The ow rate is measured with reference to the unit of
measurement of the Partial. For this reason, in case of
the unit of measurement of the Partial and Total being
dierent, as in the example shown below, it should be
remembered that the indicated ow rate relates to
the unit of measurement of the partial. In the example
shown, the ow rate is expressed in Qts/min.
The word “Gal” remaining alongside the ow rate
refers to the register of the Totals (Reset or NON Reset)
which are again displayed when exiting from the ow
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 eect.
IMPORTANT
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.
G.2.1 PARTIAL RESET (FLOW RATE MODE)
To reset the Partial Register, nish dispensing and wait for
the Remote Display to show a Flow Rate of 0.0 as indicated
in the illustration
then quickly press RESET
H CALIBRATION
When operating close to extreme use or ow rate conditions (close to minimum or
maximum acceptable values), an on-the-spot calibration may be required to suit
the real conditions in which the K24 is required to operate.
H1 DEFINITIONS
CALIBRATION
FACTOR OR
“K FACTOR”
Multiplication factor applied by the system to the electrical pulses
received, to transform these into measured uid units.
FACTORY K
FACTOR
Factory-set default factor. It is equal to 1,000. This calibration factor
ensures utmost 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 modied by calibration.
H2 CALIBRATION MODE
Why calibrate? 1
Display the currently used calibration factor:
2
Return to factory calibration (Factory K Factor) after a previous calibration by the user
3
Change the calibration factor using one of the two previously indicated 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 dierent 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 indenite time, even in the
case of a long power break; after changing the bat-
teries, calibration need not be repeated.
H.2.1 DISPLAY OF CURRENT CALIBRATION FACTOR
AND RESTORING FACTORY FACTOR.
CALCAL
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..
CAL
The ow chart alongside
shows the switchover logic
from one display page to
another
In this condition, the Reset
key permits switching
from User factor to Factory
factor.
To conrm the choice of
calibration factor, quickly
press CAL while “User” or
“Fact” are displayed.
After the restart cycle, the
K24 uses the calibration
factor that has just been
conrmed

H.2.2 IN FIELD CALIBRATION
FOREWORD
This procedure calls for the uid to be dispensed into a graduated sample container in real operating conditions ( ow rate,
viscosity, etc.) requiring maximum precision.
ATTENTION
For correct K24 calibration, it is most important to:
1
When the Factory Factor is conrmed, 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 ow rate equivalent to that of normal use, until the container is full;
4
Not reduce the ow rate to reach the graduated area of the container during the nal dispensing stage (the correct method during
the nal stages of sample container lling consists in making short
top-ups at normal operation ow 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, during which the level in the container could
drop.

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
nally achieve standby condition.
IMPORTANT: From now on, the indicated factor will become
the calibration factor used by the Meter and will continue to
remain such even after a battery change
10
NO OPERATION
The Meter stores the new work calibration factor and is
ready to begin dispensing, using the USER K FACTOR that
has just been calculated.
.
H.2.3 DIRECT MODIFICATION OF K FACTOR
If normal Meter operation shows a mean percentage error, this can be corrected by applying to the currently 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
1"4';%&K'S%;./#''''T''''O&:'5%&'S%;./#''U ( )
FCC'@'6V
FCC
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 Meter 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 Meter shows more than the real dispensed value (positive error).
