4 BECOMING AQUANINTED WITH K900
FOREWORD METER is an electronic digital meter featuring an oval-gear measurement system, de-
signed for easy and precise measuring of oils, diesel, rapsoil and antifreeze.
FUNCTIONING
PRINCIPLE The fluid, by flowing through the appliance, rotates the gears which, during their rota- tion, transfer, “volume units” of fluid. The exact measurement of the dispensed fluid is
done by counting the number of rotations made by the gears and consequently the
number of transferred “volume units”. The magnetic coupling, between the magnets
installed in the gears and a magnetic switch outside the measurement chamber, en-
sures measurement chamber sealing and ensures transmission of the pulses gener-
ated by gear rotation to the electronic board microprocessor.
OPERATIONAL
MODE In the dispensing mode (Normal Mode), the partial and the total amounts are shown in two different registers of the LCD.
The METER features a non-volatile memory for storing the dispensing data, even in
the event of a complete power break for long periods.
4.1 LCD DISPLAY (ONLY METER VERSION)
FOREWORD The “LCD” of the METER features two numerical registers and various indications displayed to
the user only when the applicable function so requires.
1Partial register (5 figures with moving comma FROM
0.1 to 99999) indicating the volume dispensed since
the reset button was last pressed

Measurement
Chamber The measurement chamber of K900 consists of two chambers held together by the
manifold.
Inside the measurement chamber are the oval gears which, on turning, generate elec-
trical pulses which are processed by the microprocessor-controlled electronic board.
By applying a suitable calibration factor (meaning a “weight” associated with each
pulse), the microprocessor translates the pulses generated by the “fluid volume” ro-
tation expressed in the set units of measurement, displayed on the partial and total
registers of the LCD.
All the meters are factory set with a calibration factor called FACTORY K FACTOR
equal to 1,000. For best meter performance the instrument can be “calibrated”.
It is possible to return to factory calibration at any time.
Baery Housing K900 is powered by two standard type 1.5 V batteries (size 1N) .
The battery housing is closed by a threaded watertight cap that can be easily
removed for quick battery change.

5 INSTALLATION
FOREWORD K900 has a 3 inch inlet and outlet. It was designed for permanent installation on a dis-
tribution line and to this purpose, the measurement chamber is fitted with a threaded
inlet and outlet.
The two cables (each one consisting of two wires) sticking out from the cover of the
measurement chamber are to be connected to K900 remote display.
WARNING The position of the filter determines the input direction of the flow.
The pulser must be connected by two wires observing the electrical specifications
shown in the diagram
Make sure a filter with adequate filtering capacity is always fied either at meter
inlet or at the entrance of the line on which the meter is fied. If solid particles enter
the measurement chamber, the gears could seize.
On installations, place the meter in a position that will enable an easy access to the
baeries compartment

6 DAILY USE
FOREWORD The only operations that need to be done for daily use are partial and/or resettable total reg-
ister resetting. The user should use only the dispensing system of K900. 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 reg-
isters. 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.
• The Partial register positioned in the top part of the display indicates the quantity
dispensed since the RESET key was last pressed
• The RESET Total register, positioned in the lower part of the display, indicates the
quantity dispensed since the last RESET Total resetting. The RESET Total cannot be
reset until the Partial has been reset, while vice versa, the Partial can always be reset
without resetting the RESET Total. The unit of measurement of the two Totals can
be the same as the Partial or else different according to the factory or user settings.
• The General TOTAL register (Total) can never be reset by the user. It continues to rise
for the entire operating life of the meter.
• The register of the two totals (Reset Total and Total) share the same area and digits of
the display. For this reason, the two totals will never be visible at the same time, but will
always be displayed alternately.
• The General Total (Total ) is shown during Meter standby
• The Reset Total is shown:
- At the end of a Partial reset for a certain time (a few seconds)
- During the entire dispensing stage
- For a few seconds after the end of dispensing. Once this short time has expired. Meter
switches to standby and lower register display switches to General Total
NOTE 6 digits are available for Totals, plus two icons x 10 / x100. The increment se-
quence is the following:
0.0 -> 99999.9 -> 999999 -> 100000 x 10 -> 999999 x 10 ->100000 x 100 -> 999999 x 100
6.1 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 ef-
fect.
stand by
A few seconds after dispensing has ended, on the lower register, the display switches from reset-
table 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 K400 again.

6.1.1 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.
6.2 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:
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 finally shows the display page where the reset
Reset Total is shown.

7 ERROR INDICATIONS
FOREWORD During the normal meter operation, unusual conditions may occur and compromise
its proper functioning. K900 electronics was designed to recognize one of these con-
ditions and inform the operator by means of a display message. In these cases, an
error indication will be displayed instead of the total; the partial indication continues
to increase while blinking.
The unusual working conditions recognized by the meter are the following:
Exceeding of the
maximum meter
flow rate
he flow rate of the fluid dispensed may exceed the max. allowed flow rate, thus dam-
aging the meter gears. Should this condition occur, “HI FLO” will be displayed:
From one of the
measurement
chambers no
pulses are found
The meter consists of two adjacent measurement chambers, held together by a
manifold. The fluid, by flowing through the appliance, rotates the gears in the two
chambers which, during their rotation, transfer, “volume units” of fluid. The exact mea-
surement of the dispensed fluid is done by counting the number of rotations made by
the gears in both chambers and consequently counting the transferred “volume units”.
Each chamber is associated with a transmission channel of “volume units”.
- chamber 1 channel 1 (CH1 WHITE wire)
- chamber 2 channel 2 (CH2 YELLOW wire).
Should the gears of one of the two chambers block or the counting electronics of one
of the two chambers break down, counting of the dispensed quantity would not be
correct.
To make the user aware of this fault, “E1” is displayed:
“E1 CH1” means that “channel 1 has stopped”: in chamber 1 no fluid is passing because
the gears are blocked or the electronics is faulty;
“E1 CH2” means that “channel 2 has stopped”: in chamber 2 no fluid is passing be-
cause the gears are blocked or the electronics is faulty.
In one measuring
chamber more
fluid is passing
than in the other
If the gears of one chamber are slightly obstructed, they slow down the transfer of fluid
which, in the other chamber, will flow more quickly. In this conditions it will be displayed:
“E2 CH1”: fluid in chamber 1 is slower than fluid in chamber 2 CHECK GEARS OF
CHAMBER 1.
“E2 CH2”: fluid in chamber 2 is slower than fluid in chamber 1 CHECK GEARS OF
CHAMBER 2.

8 CALIBRATION
FOREWORD K900 is supplied with a factory calibration that ensures precise measuring in most
operating conditions. Nevertheless, when operating close to extreme conditions, such
as for instance:
*
with fluids close to acceptable range extremes (such as low-viscosity antifreeze)
*
in extreme flow rate conditions (close to minimum or maximum acceptable values)
8.1 DEFINITIONS
Calibration fac-
tor or “K Factor” this is the 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 (EN590)
Temperature: 20°C
Flow rate: 50-255 litres/min
Even after any changes have been made by the user, the factory K factor can be
restored by means of a simple procedure.
K900 is also compatible with HVO / XTL paraffinic: EN 15940
User K Factor Customized calibration factor, meaning modified by calibration.
8.2 CALIBRATION PROCEDURE
Why calibrate? 1Display the currently used calibration factor:
2Return to factory calibration (Factory K Factor) after a previous calibration by the user
3Change the calibration factor using one of the two previously indicated procedures
FOREWORD Two procedures are available for changing the Calibration Factor:
1In-Field Calibration, performed by means of a dispensing operation
2Direct 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 meter cannot be used for normal
dispensing operations. In “Calibration” mode, the totals are not increased
ATTENTION The meter features a non-volatile memory that keeps the data concerning calibra-
tion and total dispensed quantity stored for an indefinite time, even in the case of
a long power break; aer changing the baeries, calibration need not be repeated.

8.2.2 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.
ATTENTION For correct K400 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 ac-
curate graduated indicator.
3ensure calibration dispensing is done at a constant flow rate equivalent to that of normal
use, until the container is full;
4Not reduce the flow rate to reach the graduated area of the container during the final dis-
pensing stage (the correct method during the final stages of sample container filling consists
in making short top-ups at normal operation flow rate) ;
5after 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.
6Carefully follow the procedure indicated below.

5 5 SHORT RESET KEY KEYING
K900 is informed that the calibration dispensing operation is finished.
Make sure dispensing is correctly finished before performing this operation.
To calibrate K900, the value indicated by the partial totaliser (example 155.20)
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 USER K FACTOR value change
when the operations 6 or 7 are performed.
6 SHORT RESET KEY KEYING
Changes the direction of the arrow. The operation can be repeated as many times
as you wish
7 SHORT/LONG CAL KEY KEYING
The indicated value changes in the direction indicated by the arrow
- one unit for every short CAL key keying
- continually if the CAL key is kept pressed.
(for the first 5 units slowly and then quickly).
If the desired value is exceeded, repeat the operations from point (6).
8 LONG RESET KEY KEYING
K900 is informed that the calibration procedure is finished. Before doing this,
make sure the DISPLAYED factor is the ACTUAL factor
Indicated value Real value
K900 calculates the new USER K FACTOR ; this calculation could require a few
seconds, depending on the correction to be made.
During this operation the arrow disappears but the CAL indication remains.
If this operation is performed aer operation (5), without changing the indicated
value, the USER K FACTOR would be the same as the FACTORY K FACTOR,
thus it is ignored.

8.2.3 DIRECT MODIFICATION OF K FACTOR
This procedure is especially useful to correct a “mean error” obtainable on the basis of several performed dispens-
ing operations. If normal K900 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:
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 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).

1
NONE
K900 in normal mode, not in counting mode
2
LONG CAL KEY KEYING
K900 enters calibration mode, shows “CAL” and displays the calibration factor
being used instead of the partial. The words “Fact” and “User” indicate which of
the two factors (factory or user) is currently being us
3
LONG RESET KEY KEYING
K900 shows “CAL” and the partial at zero.
K900 is ready to perform in-field calibration by dispensing
4
LONG RESET KEY KEYING
We now go on to Direct change of the calibration factor: the word “Direct” ap-
pears together with the Currently Used calibration factor. In the boom le part
of the display, an arrow appears (upwards or downwards) defining the direction
(increase or decrease) of change of the displayed value when subsequent opera-
tions 5 or 6 are performed
5
SHORT RESET KEY KEYING
Changes the direction of the arrow. The operation can be repeated to alternate
the direction of the arrow.
6
BSHORT/LONG CAL KEY KEYING
The indicated value changes in the direction indicated by the arrow
- one unit for every short CAL key keying
- continually if the CAL key is kept pressed. The speed increase rises by
keeping the key pressed.
If the desired value is exceeded, repeat the operations from point (5).

9.1 CONFIGURATION OF THE UNITS OF MEASUREMENT
The METER feature a menu with which the user can select the main measurement unit, Quarts (Qts), Pints (Pts),
Litres (Lit), Gallons (Gal); he combination of the unit of measurement of the Partial register and that of the
Totals is predefined according to the following table:
Combination no. Unit of Measurement
Partial Register Unit of Measurement Totals Register
1Litres (L) Litres (L)
2Gallons (Gal) Gallons (Gal)
3Quarts (Qts) Gallons (Gal)
4Pints (Pts) Gallons (Gal)
To choose between the 4 available combinations:
