4 GENERAL INFORMATIONS
The K40 mechanical flow meter with oval gears has been designed to allow accurate measurement of
oil or other liquids that are compatible with the component materials. The oval gears of the measuring
chamber (see diagram) are moved by the fluid, and they activate the gear train housed in the lid of the
flow meter body, which transmits the motion to the counter.
The counter is fitted with a total indicator, which cannot be reset, in litres or quarter gallons and with
a partial indicator which can be reset using the button provided.
ATTENTION To ensure correct and safe use of the flow meter, it is necessary to read
and comply with the instructions and warnings contained in the present
manual.
Incorrect installation or use of the flow meter could cause danger for
people and things.
5 INSTALLATION
The K40 flow meter can be installed in any position, with flexible and rigid piping as well as directly
on pumps and tanks.
The flow meter has one preset flow direction.
If solid particles get into the measuring chamber, they could prevent the correct operation of the oval
gears.
Therefore, make provision to filter the fluid by installing a filter before the flow meter (recommended
filter: 400 ŋ).

6 USE
Once installed, the K40 flow meter is ready for use. Press the RESET button until the partial indicator
returns to zero.
The total indicator cannot be reset in any way. Make sure that, during use, the operating pressure does
not exceed the valued indicated in the “Technical Data” section.
7 MAINTENANCE
If installed and used correctly, the K40 flow meter does not require any ordinary maintenance work.
Inadequate filtration on the line before the flow meter could cause the measuring chamber to wear
out or become clogged, which may consequently affect the accuracy of the flow meter. Should this
problem arise (see “Problems, Causes and Solution” section), disassemble the measuring chamber as
shown in the “Disassembly/Reassembly” section.
ATTENTION Before disassembling, make sure that all the liquid has been removed
from the flow meter and the pipes connected to it.
To carry out the required cleaning, use a soft brush or a small tool (a screwdriver for example), taking
care not to damage the measuring chamber during cleaning.
Carefully inspect the flow meter and replace any damaged parts using only original spare parts, as
shown in the “Spare Parts Exploded Diagram”.
8 DISASSEMBLY AND REASSEMBLY
The K40 flow meter can be easily disassembled into its main components, without having to separate
the body from the piping.
MEASURING CHAMBER
To access the measuring chamber:
ARemove the rubber protection
BUnscrew the 6 screws located under the flow meter body
CRemove the lid
DRemove the gasket and the oval disk
ERemove the gears
To reassemble the parts, carry out the above-mentioned steps in reverse order, taking particular to:
-Install the gasket seals correctly after having checked and lubricated them;
-Tighten the screws correctly;
-Ensure that, if you hold the flow meter with the inlet facing down, the outlet gear is on the right-
hand side;
-Check that the oval gears are turning correctly;
-Check that the gears on the lid correspond with the that in the chamber outlet.
