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 dispens-
ing nozzle. In order to improve the life of the turbine, it is recommend-
ed 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
High ow rate 120 l/min For installations on system, position K24 so that the
Low ow rate 60 l/min battery housing can be easily reached.
G DAILY USE
The only operations that need to be done for daily use are partial and/
FOREWORD
or resettable total register resetting. The user should use only the dis-
pensing 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 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.
Main components: K24 Pulser

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

the system.
K24 features two low-battery alarm levels:
1 When the battery charge falls below the rst level on the LCD,

After changing the batteries, the meter does not need calibrating again.
CLEANING Only one operation is necessary to clean the k24.
After removing k24 from the plant where it was built
in, any residual elements can be removed by washing
or mechanically-handling.
If this operation does not restore a smooth rotation of
the turbine, it will have to be replaced.
