Gas Meter Itron G25

Gas Meter Itron G25 diaphragm meters. Through decades of knowledge in field commercial and industrial diaphragm gas meters, G25 and G40 meter sizes combine accuracy of measurement and long life in field.

Application :

  • Used for applications requiring high precision and large rangeability at low pressure (below 1 bar gauge).
  • Due to the volumetric principle of the diaphragm meter, its metrology is not influenced by installation conditions.
  • Designed for use with natural gas, manufactured gas and other non-corrosive gases.
  • Approved for fiscal use.

Benefits :

  • Ready for remote reading and data management
  • Long-term accuracy and reliability
  • Very low pressure loss
  • Robust, maintenance-free meter
  • Large cyclic volumes
Gas Meter Itron G25 Made of four main parts :
  1. The measuring unit mainly consisting in :
    – Four measuring chambers
    – Two sliding valves
    – An outlet pipe
  2. A Steel casing where 1 or 2 connectors are fitted
  3. A magnetic coupling or a stuffing box transmits the movement of the measuring unit to the totalizer
  4. A totalizer is available in different versions depending on the application
