C MACHINE DESCRIPTION
K33 atex is mechanical owmeter with nutating disk, designed
toallow a precise measurement of Diesel oil or other uids
compatible with the manufacturing material. The nutating disk
of the metering chamber (seediagram 1, drawing “15”), which
is setin motion by the uid itself, drives thegear train located in
the cover of themeter body (drawing “8”) which transmitsthe
motion to the meter (pos. “6”). The meter is equipped with a
non-resettable litre totaliser and a batch register which can be
reset by means of a knob (Pos. “2”) whose unit digit is provided
with marks for the readout ofthe tenths of a litre.
WARNING
To ensure a proper and safe use of the meter it is necessary to read and follow the instructions and warnings
contained in this manual. An improper installation
or use of the meter may cause damage to objects and
people.

FOREWORD
Denition of zones as shown in directive 99/92/CE
ZONE 0
Place where an explosive atmosphere made up of a mix of air and inam-
mable substances in the form of gas, vapour or mist is continuously pres-
ent, either for long periods or frequently.
Note: Generally speaking, said conditions, when they occur, involve the
inside of tanks, pipes and containers, etc.
ZONE 1
Place where it is probable that an explosive atmosphere, made up of a
mix of air and inammable substances in the form of gas, vapour or mist,
can occur occasionally during normal operation.
Note: Said zone can also include:
- places in the immediate vicinity of zone 0;
- places in the immediate vicinity of supply openings;
- places in the immediate vicinity of lling and and emptying openings;
-
places in the immediate vicinity of appliances, protection systems and fragile
glass and ceramic components, or components made of other similar materials;
- places in the immediate vicinity of inadequately sealed stung boxes,
e.g., on pumps and valves with stung box.
ZONE 2
Place where it is improbable that an explosive atmosphere, made up of a
mix of air and inammable substances in the form of gas, vapour or mist,
can occur during normal operation, but which, if it does occurs, only per-
sists for a short time.
Note: Said zone can include, among others, places surrounding the zones 0 or 1.
ZONE 20
Place where an explosive atmosphere in the form of a cloud of combus-
tible powders in the air is continuously present, either for long periods
or frequently.
Note: Generally speaking, said conditions, when they occur, involve the
inside of tanks, pipes and containers, etc.
ZONE 21
Place where it is probable that an explosive atmosphere, in the form of a cloud of
combustible powders in the air, can occur occasionally during normal operation.
Note: Said zone can include, for example, among others, places in the im-
mediate vicinity of powder loading and emptying points and places where
powder layers form or which, during normal operation, could produce an
explosive concentration of combustible powders mixed with the air.
ZONE 22
Place where it is improbable that an explosive atmosphere, in the form of
a cloud of combustible powders in the air, occur during normal operation
but which, if it does occur, only persists for a short time.
Note: This zone can comprise, among others, places near appliances, pro-
tections systems and components containing powder, out of which the
powder can come out due to leaks with the formation of powder deposits
(e.g., milling salt, where the powder comes out of the mills and deposits).

WARNING
BEFORE ANY OPERATION, ENSURE TO BE OUT OF
POTENTIALLY EXPLOSIVE AREAS
The meter must never be operated before the delivery and
suction lines have been connected.
PRELIMINARY
CHECK
- Verify that all components are present. Request any missing parts
from the manufacturer.
- Check that the meter has not suered any damage during transport
or storage.
WARNING
IF VALVES IN THE CIRCUIT ARE TO BE INSTALLED, MAKE
SURE THEY ARE EQUIPPED WITH OVERPRESSURE SYSTEM.
CLEAN THE TANK AND MAKE SURE IT IS WELL-VENTILATED
(RECOMMENDED OPENING PRESSURE: 3 psi)
APPLY THE QUICK COUPLING TO THE TANK CORRECTLY
AND SAFELY
L CALIBRATION
FOREWORD
K33 ATEX are pre-calibrated in factory to be used with Diesel
oil. As specic operating conditions (suchas real ow rate,
nature andtemperature of the measured uid) may aect
the meter accuracy, a re-calibration should be carried out
afterthe installation has been completed. A new calibration
is necessary eachtime the meter is disassembled formaintenance operations or when it isused to measure uids that
dier fromDiesel oil.
CALIBRATION
PROCEDURE
1
Unscrew the plug (see diagram 1,pos. “14”).
2
Purge the system (pump, pipelines, meter) of air by dispensing until the ow stream is full and steady.
3
Stop the ow by shutting o the nozzle, but let the pump
running
4
Reset the batch register by means of the reset knob (pos. “2”).
5
Dispense at the ow rate which thebest accuracy is required
at, by using a calibration container having a capacity not
lower than 20 litres. Do not reducethe ow in order to reach
the graduated zone of the calibration container. Theright
method is to start and stop the fullow repeatedly until the
required llingis obtained.
6
Compare the indication of the calibration container (real
value) withthe one of the meter (indicated value).
- If the indicated value is higher than the real value, loosen
the screw (pos. “12”);
- If the indicated value is lower than the real value, tighten
the screw (pos. “12”).
7
Repeat the operations 4 to 6 until accuracy is satisfactory
8
Tighten the plug (pos. “14”) again. The O ring which the
calibration screwis provided with, has the function to avoid
accidental loosening of the adjustment screw but does not
haveany sealing functions. Therefore it is always necessary
toproperly x the plug with the sealinggasket (pos. “12”)..
M EVERY DAY USE
WARNING THE WORKING OPERATIONS MUST ALWAYS BE
GUARDED BY THE OPERATOR.
Should any sealants be used on the suction and delivery circuit of the pump, make sure that these products
are not released inside the meter.
Foreign bodies in the suction and delivery circuit of
the pump could cause malfunctioning and breakage
of themeter components.
While dispensing, do not inhale the pumped product
IF ANY TREATED FLUID LEAKS OUT DURING DISPENSING, TAKE ALL STEPS NECESSARY TO ENSURE THE
LEAKED FLUID IS CLEANED UP AND SAFE AS SPECIFIED ON THE PRODUCT TECHNICAL SHEET.
USE
After installation and calibration K33 ATEX is ready to work.
Turn the reset knob (see diagram 1,pos. “12”) (clockwise if it
is mounted on the left of the meter and anticlockwiseif it is
mounted on the right) until the batch register is completely
reset. The totaliser cannot be reset in any way. Make sure that
during use pressure does not exceed the value indicated insection “Technical data”.
USE BY GRAVITY
K33 ATEX can also be used in fuel units which are not
equipped with pump sand where the ow is generated by
the dierence in fuel level between the tank and the nozzle
outlet. As a reference, a system composed ofa tank o the
ground, with the meter installed right at the bottom of the
tank,a 3-m long 1’’ exible pipe and a manual nozzle type Self
2000, guarantees aow rate of approximately 30 litres/minute if the dierence in level is higherthan 1.5 metres. Longer
pipes or nozzles producing higher pressure losses reduce the
owin respect to the existing dierence inlevel. Use by gravity is not recommended with dierences in level lower than
1metre, as the consequent reduced owrate causes the meter to work outside its guaranteed accuracy range. On eld
calibration is always advisable in case of gravity installations.
N MAINTENANCE
FOREWORD
No ordinary maintenance is required provided that the meter K33 ATEX
is properly installed and used. An incorrect ltering on the meter inlet
may block or wear out the measuring chamber, thus aecting the meter accuracy. Should this problem occur (see section”Problem, Causes
and Solutions”) disassemble the measuring chamber, as shown in
section“Disassembling/Reassembling”.
Necessary cleaning can be carried out by means of a soft brush or small
tool (i.e. a screwdriver). During cleaning be careful not to damage the
chamber or the disk. Carefully check the meter and replace the parts
which have suered any possible damage. Only use the original spare
part kits shown in diagram 1 “Exploded view and spare part list”. A new
calibration is always necessary after cleaning or replacing the meter
parts.
WARNING TO MAINTAIN THE SAFETY OF THE APPLIANCE, IT IS
MANDATORY TO REPLACE THE DAMAGED PARTS.
FOR SAFETY PURPOSES, YOU MUST USE ONLY GENU-
INE SPARE PARTS.
Safety instructions
