G INSTALLATION
WARNING
Installation, assembly and maintenance operations of
the K24 , must only be performed by personnel quali-
fied to operate in HAZARDOUS LOCATIONS ZONE1.
K24featuresa threaded,perpendicularinletand 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
For installations on system, position meter so that the
baery 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
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 replace
the thread tape or sealant. Refer to the Troubleshooting
Section
To minimize static electricity build up,use only static
conductive hose R<1MΩm when metering flammable
fluids, and keep the fill nozzle in contact with the con-
tainer being filled during the filling process.
All parts of our system must be incontinuity and
grounded.
DO NOT exceed 145 psi - 20 bar line pressure.
DO NOT install additional foot valve or check valve
without a pressure relief valve; otherwise the meter
may rapture.
PULSER
CONNECTIONS The electrical signal between K24 PULSER and the control unit device must be protected by intrinsically
safe barrier.
The electrical limits of signal are the follows :
Ui = 12 V
Ii = 100 mA
Pi = 0.3 W
The barier must be properly connected to an earth
grounded.
Improper installation of this meter and barier could re-
sult in death or serious injury.
H DAILY USE
FOREWORD The only operations that need to be done for daily use are partial
and/or reseable total register reseing. 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
reseable total to general total display is automatic and tied tophases and times that are
in factory set and cannot be changed.
NOTICE
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
H.1 DISPENSING IN NORMAL MODE
FOREWORD Normal mode is the standard dispensing. While the count is made,
the partial and reseable total are displayed at the same time (reset
total).
NOTICE
Should one ofthe keys be accidentally pressedduring
dispensing, this will have no effect.
stand by A few seconds aer dispensing has ended, on the lowerregister, the
display switches from reseable total to generaltotal: 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.
H.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”.
Aer 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, aer a few moments, the reset total is replaced bythe non
reseableTotal.
H.1.2 RESETTING THE RESET TOTAL
The reset total reseing operation can only be performed
aer reseing 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:
1Wait for the display to show normal standby display page
(with total only displayed)
2Press the reset key quickly
3The meter starts to reset the partial
4While the display page showing the reset total is displayed
Press the reset key again for at least 1 second
The display screen again shows all the segments of the
display followed by all the switched-off segments and fi-
nally shows the display page where the reset Reset Total
is shown.
H.2 DISPENSING WITH FLOW RATE MODE DISPLAY
It is possible to dispense fluids, displaying at the same time::
1the dispensed partial
2the Flow Rate in [Partial Unit / minute] as shown on the
following display page:
Procedure for entering this mode:
1wait for the Remote Display to go to Standby, meaning the
display screen shows Total only
2quickly press the CAL key.
3Start 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.
NOTICE
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 be-
ing 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 re-
fers 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.
NOTICE
Even though in this mode they are not displayed, both
the Reset Total and the General Total (Total) increase.
Their value can be checked aer dispensing has termi-
nated, returning to “Normal” mode, by quickly pressing
CAL.
H.2.1 PARTIAL RESET (FLOW RATE MODE)
To reset the Partial Register, finish dispensing and wait for
the Remote Display to show a FlowRate of 0.0 as indicated
in the illustration
then quickly press RESET
I CALIBRATION
When operating close to extreme use or flow rate conditions (close to minimum or maxi-
mum acceptable values), an on-the-spot calibration maybe required to suit the real condi-
tions in which the K24 is required to operate.
I.1 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 - 68°F
Flow rate: 50 lit/min (13 GPM)
Even aer any changes have been made by the user, the factory k
factor can be restored by means of a simple procedure.
USER K FAC-
TOR: Customized calibration factor, meaning modified by calibration.
I.2 CALIBRATION MODE
Why calibrate? 1Display the currently used calibration factor:
2Return to factory calibration (FactoryK Factor) aer a pre-
vious calibration by the user
3Change 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
NOTICE
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; aer changing the bat-
teries, calibration need not be repeated.

I.2.2 IN FIELD CALIBRATION
FOREWORD This procedure calls for the fluid to be dispensed into a graduated
sample container in real operating conditions ( flow rate, viscosity,
etc.) requiring maximum precision.
NOTICE
For correct K24 calibration, it is most important to:
1When the Factory Factor is confirmed, the old User factor is deleted
from the memory
2use a precise Sample Container with a capacity of not less than 5
litres, featuring an accurate graduated indicator.
3ensure calibration dispensing is done at a constant flow rate equiva-
lent to that of normal use, until the container is full;
4Not 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);
5aer dispensing, wait a few minutes to make sure any air bubbles are
eliminated from the sample container; only read the Realvalue at the
end of this stage, during which the level in the container could drop.

The Meter enters calibration mode, shows <<CAL>> and displays
the calibration factor in use instead of partial. The words “Fact” and
“USER” indicate which of the two factors (factory or user)is currently
in use.
Important: This factor is that which the instrument also uses for field
calibration measurement operations

4DISPENSING INTO SAMPLE CONTAINER
Without pressing any key, start dispensing into the sample container
Dispensing can be interrupted and started again at will. Continue
dispensing until the level of the fluid in the sample container has
reached the graduated area. There is no need to reach a preset
quantity.

SHORT RESET key keying
The Meter is informed that the calibration dispensing operation is
finished.
Make sure dispensing is correctly finished before performing this
operation. To calibrate the Meter, the value indicated by the partial
totaliser (example 9.800) must be forced to the real value marked
on the graduated sample container. In the boom le part of the
display an arrow appears (upwards and downwards), that shows the
direction (increase or decrease) of the value change displayed when
the following operations 6 or 7 are performed.

SHORT/LONGCAL key keying
The indicated value changes in the direction indicated by the arrow

by keeping the key pressed. If the desired value is exceeded, repeat
the operations from point (6).

Before performing this operation, makesure the INDICATED value is
the same as the REAL value.
Indicated value Real value
The Meter calculates the new USER K FACTOR ; this calculation
could require a fewseconds, depending on the correction to be made
ATTENTION: If this operation is performed aer action (5), without
changing the indicated value, the USER K FACTOR would be the
same as the FACTORY K FACTOR, thus it is ignored.
9NO OPERATION
At the end of the calculation, the new USER K FACTOR is shown
for a few seconds, aer 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 evenaer a baery 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.
.
I.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 percent-
age. In this case, the percentage correction of the USER K FACTOR must be calcu-
lated 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 Meter indicates less than the real dispensed value (negative error) the new cali-
bration 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).

BY THE USE OF BATTERIES NOT SUITABLE.
K24 should be installed in a position allowing the bat-
teries to be replaced without removing it from the
system.
BATTERIES Check the baeries and terminals at least every year
to ensure properoperation. Itis stronglyrecommend-
ed that terminals be cleaned annually
K24 features two low-baery alarm levels:
1When the baery charge falls below the first level on the
LCD, the fixed baery symbol appears. In this condition,
K24 continues to operate correctly, but the fixed icon
warns the user that it is ADVISABLE to change the bat-
teries.
2 If K24 operation continues without changing the baer-
ies, the second baery alarm level will be reached which
will prevent operation. In this condition the baery icon
starts to flash and is the only one to remain visible on the
LCD.
WARNING
During meter removal, liquid may spill. Follow the liq-
uid manifacturer’s safety precautions for clean up of
minor spills.
TO REMOVE
BATTERY 1Ensure all liquid is drained from the meter. This could include draining the hose, meter, nozzle or pipe
2

be resumed
The K24 will display the same Reset Total, the same Total and the same Partial
indicated before the baeries were changed. Aer changing the baeries, the
meter does not need calibrating again.
CLEANING Only one operation is necessary to clean the k24. Aer
removing k24 from the plant where it was built in, any re-
sidual elements can be removed by washing or mechani-
cally-handling. If this operation does not restore a smooth
rotation of the turbine, it will have to be replaced.
WARNING
Do not discard the old baeries 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
