Grand gas meters are used to measure the volume of: natural gas; liquefied gas vapours; other non-aggressive gases.

Field of application:

Grand gas meters allow for metering of consumed gas: in apartments; in private houses; in other utility and household facilities.


  • Instrument's compactness is conditioned by the use of the jet method, it ensures small overall dimensions of the instrument;
  • Absence of moving mechanical parts and high reliability due to this, also conditioned by the chosen jet method of gas consumption volume metering;
  • Simple mounting (gas welding operations not required) allows quick and inexpensive replacement of the old meter;
  • The meter can be mounted in any position convenient for the client, vertical or horizontal;
  • The manufacturer provides a long-term 12 year warranty.


By the colour of casing:

  • White;
  • Gray;
  • Orange.
