Range: G1.6, G2.5, G4
EN 1359 & O.I.M.L compliance
Design
Long -term accuracy & safety
Ready for remote reading & data management
Quality
World-class, ISO9001 certified, European Engineering and
Manufacturing
APPLICATION
The ITRON, with an installed base of over 30 million units, is a
versatile meter that makes it the preferred choice of many large
utilities world-wide.
METROLOGY
The ITRON meets O.I.M.L, EN 1359 and MID (certificate delivered by
the LNE), and more than 25 national metrological standards
(DVGW,NMI Class 1....).
Its design and the careful choice of materials enable the ITRON to
meet the highest demand in international markets in terms of
accuracy and long-term stability.
During the preliminary test controls on the sonic nozzle test benches,
all meters are tested at Qmin, 0.2 Qmax and Qmax.
OPERATING PRINCIPLE
The ITRON is a positive displacement diaphragm gas meter with a
stand-alone twin chamber measuring unit.
The twin chambers are each fitted with a flexible and gas-tight
diaphragm which is moved by the differential between the inlet and
outlet pressure. The Gas enters one side of the diaphragm pan while
on the other side it comes out through a separate port on the valve.
When one side is full, the rotating mono-valve moves on to the next
position, allowing the gas to fill the empty side. A transmission gear
and a mechanical coupling or stuffing box transfer the reciprocating
motion to the mechanical retrofitable index. The measuring unit is
housed in a robust gas-tight casing.
CONSTRUCTION
With its casing in steel, high protection against corrosion is ensured
by 500 hours salt fog spray test resistant cataphoresis treatment. The
aluminum version can withstand up to 1000 hours salt fog spray test.
The extreme strength of the case joint is achieved by rolling the belt &
compressing the flanges into contact with a sealant applied between
the faces. This forms a joint which is both gas-tight and fire- resistant.
MEASURING UNIT
The achievement of the fixed stroke mechanism is the result of
precision and high quality automation, and eliminates the need for an
adjustable tangent. This confines all registration adjustments to the
accessible change wheels behind the index.
The long life synthetic diaphragms, coupled to the well-proven
movement design, combine to give excellent stability and accuracy
during the whole life of the metre.
All materials have been selected for their superior resistance to
chemicals and gas. The valve and the grid, thanks to a special
Bakelite formulation, enjoy high gliding properties and are protected
against premature wear.
Finally, a back-run stop prevents the metre from running backwards
in case of tampering.
INDEX
The metres are available with metric or cubic inch indexes. They
come with a permanent magnet for pulse generation and can be
retrofitted with a pulse transmitter. Ip54 and Ip67 versions are
available for specific environments.
QUALITY ASSURANCE
Quality assurance procedures- such as ISO 9001- and strict controls
throughout the manufacturing process ensure a very high quality
level.

This manual will assist you in installing, using and maintaining your flow meter. It is your responsibility to make sure that all
operators have access to adequate instructions about safe operating and maintenance procedure.
Operating Principle:
Gas flows through the turbine housing causing an internal rotor to spin. As the rotor spins, an electrical signal is generated in the pickup coil. This signal is converted into engineering units (liters, cubic meters, gallons etc.) on the local display where is applicable. Optional accessory modules can be used to export the signal to other equipment.
Upon receipt, examine your meter for visible damage. The turbine is a precision measuring instrument and should be handled carefully. Remove the protective plugs and caps for a thorough inspection. If any items are damaged or missing, contact
Make sure the turbine flow model meets your specific needs. For your future reference, it might be useful to record this information on nameplate in the manual in case it becomes unreadable on the turbine. Refer to the nameplate for your customized products specification.

FUJI developed the first infrared gas analyzer in Japan to use mass-flow sensors. Since then, we have supplied customers with various types of gas analyzers to support environmental preservation and control efforts. These efforts include measurements of atmospheric pollution and detection of low density of SOx and NOx, generated by incinerating facilities and boilers. FUJI's gas analyzers are widely used to monitor the atmosphere to help maintain a cleaner natural environment.
