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
which is Alodine surface pre-treated followed by baked Woodland Grey polyester powder coat.
meter life. The pressure absorption of the Model 750 is 125 Pascals (Pa) at a low rate of 6m³/h of Air (7.5 m³/h of Natural Gas).
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 bevretrofitted 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 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.
