Jual Landis Gyr Gas Meter Model 750


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.

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.
