Residential Diaphragm Gas Meter ITRON (MID approved) Steel Version Basic Features 3 Compact size: 1.2 dm cyclic volume 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.
