FOREWORD
K24 features a threaded, perpendicular inlet and outlet (1” NPT
or
BSP
male and female that can be combined together). It has been
designed to be easily installed in any position: fixed in-line or mobile
on a dispensing nozzle. In order to improve the life of the turbine, it is
recommended to fit a strainer before the meter itself
ATTENTION
For installations on system, position meter so that the
battery housing can be easily reached.
Connections
To protect against the leakage, make sure all threads are
sealed with two or three turns of thread tape or a sealing
compound compatible with the liquid being metered
ATTENTION
Make sure the thread tape or sealing compound does
interfere with flow
Make sure there are no leaks in the connections.
To seal leaks, remove and inspect the meter and re-
place the thread tape or sealant. Refer to the Trouble-
shooting Section
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 dis-
pensing system of k24. Occasionally the meter may need to be con-
figured or calibrated. To do so, please refer to the relevant chapters.
Below are the two typical normal operation displays. One display page shows the par-
tial 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 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 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
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 resettableTotal.
G.1.2 RESETTING THE RESET TOTAL
VALID JUST FOR METER VERSION WITH SILVER LABEL
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.
C.2
DISPENSING WITH FLOW RATE MODE DISPLAY
VALID JUST FOR METER VERSION WITH SILVER LABEL
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.
IMPORTANT
The flow 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
different, as in the example shown below, it should be
remembered that the indicated flow rate relates to
the unit of measurement 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 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. If one of the two keys RESET or
CAL is accidentally pressed during the count, this will have no effect.
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, 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
H
CALIBRATION
When operating close to extreme use or flow 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 fluid 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
diesel
Temperature: 20°C
Flow rate: 50 lit/min (13 GPM)
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.
H2
CALIBRATION MODE
Why calibrate? 1
Display the currently used calibration factor:
2
Return to factory calibration (Factory K Factor) after a pre-
vious calibration by the user
3
Change the calibration factor using one of the two previ-
ously 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 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 bat-
teries, calibration need not be repeated.
H.2.1 DISPLAY OF CURRENT CALIBRATION FACTOR
AND RESTORING FACTORY FACTOR.

tor 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 fac-
tor set by the user is being used..

H.2.2 IN FIELD CALIBRATION
FOREWORD
This procedure calls for the fluid to be dispensed into a gradu-
ated sample container 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 equiva-
lent to that of normal use, until the container is full;
4 Not reduce the flow rate to reach the graduated area of the con-
tainer 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, during which the level in the container could
drop.

The Meter 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 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 ap-
plying 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 opera-
tor 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 Meter indicates less than the real dispensed value (negative error) the new calibra-
tion factor must be higher than the old one as shown in the example. The opposite ap-
plies if the Meter shows more than the real dispensed value (positive error).

L MAINTENANCE
BATTERY
REPLACEMENT
Use 2x1.5 V alkaline batteries size AAA
WARNING
K24 should be installed in a position allowing the
batteries to be replaced without removing it from
the system.
BATTERIES
Check the batteries and terminals at least every
year to ensure proper operation. It is strongly rec-
ommended that terminals be cleaned annually
K24 features two low-battery alarm levels:
1
When the battery charge falls below the first level on the LCD,
the fixed battery symbol appears. In this condition, K24 con-
tinues to operate correctly, but the fixed icon warns the user
that it is ADVISABLE to change the batteries.
2
If K24 operation continues without changing the batteries,
the second battery alarm level will be reached which will
prevent operation. In this condition the battery icon starts to
flash and is the only one to remain visible on the LCD.
TO REMOVE BATTERY
ATTENTION
During meter removal, liquid may spill. Follow the
liquid manifacturer’s safety precautions for clean
up of minor spills.
1
Ensure all liquid is drained from the meter. This could
include draining the hose, meter, nozzle or pipe
2
Wear protective clothing as necessary, loosen both ends
of the meter. Use a wrench only on the meter’s flat metal
surfaces
3
If the meter is not immediately installed again, cap the
hose end or pipe to prevent spills
To change the
batteries, with
reference to the
exploded diagram
positions, proceed
as follows
1
Press RESET to update all the totals
2
Loosen the 4 fixing screws of the lower cover
3
Remove the old batteries and disconnect the plug
4
Place the new batteries in the same position as the old ones
(sure to put the battery in the correct way)
5
close the cover again, by positioning the rubber pro-
tection as a gasket
6
K24 will switch on automatically and normal opera-
tion can be resumed
The K24 will display the same Reset Total, the same Total and the same Partial indi-
cated before the batteries were changed.
After changing the batteries, the meter does not need calibrating again.
ATTENTION
Never blow compressed air trought the meter. It
could damage the rotor.
CLEANING
Only one operation is necessary to clean the k24.
After removing k24 from the plant where it was built
