General Details Typical Accuracy Curve
Housed in a compact aluminium case, the Model 750 is a slow revving high 3 SIGNATURE
capacity gas meter. Its 2 litre per cycle diaphragm operates at a rate 60% 2
slower than its 1.2 litre rivals. This design minimises the speed of internal 1

The outstanding design features of the Model 750 gas meter such as its tangent
control, large cyclic volume and magnetic drive index provide unparalleled DRAFT No. 5
accuracy from 10 litres/hr to 7.5m3/hr. Our modern calibration and test facilities
are accredited to ISO/IEC 17025.
Pressure Absorption
The Model 750 has a low pressure absorption due to the tangent assembly, sliding Weight 2.7 kg 152.4
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 70
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
6 m3/hr of Air (7.5 m3/hr of Natural Gas).
Accuracy Retention 249
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. 227 162
