CGR-FX Rotary Gas Meter

Rotary gas meters are positive displacement meters, designed to measure quantity of gas, for custody transfer or technical measurement applications.
The CGR-FX Meters are applied in measurement systems where high accuracy is required:
• transportation and distribution of natural gas
• primary and secondary measurements
• control metering of natural gas and non aggressive technical gases in industry

Double-body design of CGR-FX gas meter is a robust product with high endurance, able to operate in heavy duty environment. These attributes differ the CGR-FX from the other models of rotary gas meters available on the market.

The technical parameters and metrological properties significantly exceed the level achieved by traditional rotary gas meters.

CGR-FX rotary gas meters are optimal solution wherever occur the significant fluctuations in gas consumption and the accuracy of measurement is crucial factor to be controlled.

The CGR-FX are most commonly used in systems:

  • in low, medium, and high-pressure metering and reduction stations,
  • metering distribution systems and their connections to transmission lines,
  • control gas measurement,
  • measuring of industrial gases, including air, propane-butane, acetylene, and hydrogen.

The double-body design of the CGR-FX gas meter ensures complete resistance of the measuring assembly that could be caused by installation stresses and by the stresses combined with measuring gas at pressures and temperatures different from those of the surrounding environment. This feature allows to achieve wide range of rangeability with the maintain of measurement precision.
