E OPERATING MODES
OPERATING
The user can choose between two different operating modes:
MODES 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 K24 which remains isolated from the fluid-bath measure-
ment chamber and sealed from the outside by means of a cover.
1 - Normal Normal Mode: Mode with display of Partial and Total dis-
Mode pensed quantities
2 - Flow rate Flow Rate Mode: Mode with display of Flow Rate, as well as
Mode Partial dispensed quantity.
F INSTALLATION
FOREWORD K24 features a threaded, perpendicular inlet and outlet (1" NPT
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
4 Should one of the keys be accidentally pressed during
dispensing, this will have no effect.
1
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.

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

BATTERY
Use 2x1.5 V alkaline batteries size AAA
REPLACEMENT
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.
Indicated value Real value 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
