DOMESTIC GAS METER 750 SERIES

DOMESTIC GAS METER 750 SERIES.

General Details
Housed in a compact aluminium case, the Model 750 is a slow revving high
capacity gas meter. Its 2 litre per cycle diaphragm operates at a rate of 40%
slower than its 1.2 litre rivals. This design minimises the speed of internal
components and coupled with high quality materials wear rates are reduced
ensuring long term accuracy retention.
The Model 750 has a capacity of 7.5m³/h of Natural Gas (SG0.62) or 6m³/h of
Air at 125Pa pressure drop, a standard proven in Australia and throughout
the world to ensure durability and reliable accuracy for periods of beyond
20 years. Suitable for granny flat sub meters.
Accuracy
The outstanding design features of the Model 750 gas meter such as its
tangent control, large cyclic capacity and magnetic drive index provide
unparalleled accuracy from 10 litres/h to 7.5m³/h. Our modern calibration and
test facilities are accredited to ISO/IEC 17025.
Pressure Absorption
The Model 750 meter has a low pressure absorption due to the tangent assembly,
sliding low friction valves, and large cyclic volume (2 dm³/cycle),
which ensures extended field life and long term accuracy retention.
Pressure absorption across the meter reflects how hard the meter is working
and is directly proportional to the component wear rate and subsequent
meter life. The pressure absorption of the Model 750 is 125 Pascals (Pa) at a
flow rate of 6m³/h of Air (7.5 m³/h of Natural Gas).
Accuracy Retention
The initial accuracy of a meter is easy to achieve by using calibration to pass
initial testing. However, sustained accuracy over time comes down to the
quality, design and construction of the meter. The Model 750 has been
designed for long-term stability and extended field life.
Product Enhancements
Every Model 750 gas meter is supplied pulse ready so that the meter can be
retrofitted with a pulse output module for advanced metering applications
without the need to replace the meter index.
The Model 750 is also available with a top reading index allowing ease of
reading when the meter is located in a low height. The model 750 is also
available with Viton o-rings for aggressive gas applications.
Endurance Testing
Endurance testing to the most stringent world requirements has been
conducted on the Model 750 that show long term accuracy retention.
The Model 750 meter exceeds the endurance testing requirements of the
European Standard EN1359:1999, American National Standard ANSI B109.1,
Australian Standard AS4647:2005, and OIML Recommendation 31.
