Gas Meter



Why choose it

The MGM100 meter is a volumetric measuring instrument with deformable walls for natural gas, manufactured gas, LPG and technical gases, for industrial use.

The design and construction are carried out using the highest standards, and in compliance with EN1359 and the MID Directive. The high-precision and accuracy of the measurement is guaranteed by the production control process and by an automated calibration system, applied at the Metrology Laboratory on 100% of the samples produced. 

The quality of the plastic and metal components used allows the meters a high sensitivity, even with a minimum gas flow, and excellent performance over time.

The accuracy and reliability over time of the measurement is guaranteed by the well-established mechanical principle of measurement that takes place with membrane system and drawers.

Normative requirements

  4. High measurement stability 
  5. Low noise and pressure absorption 
  6. Equipped with mechanical anti-return device 
  7. All models are designed to be connected to a low frequency (LF) pulse generating sensor
  8. Measurement and counting units are not responsive to magnetic tampering
  9. Meters are available on request with different types of connection and inter-axis distance   
  10. Mechanical transmission of the measurement to the dial
  11. RAL 9000 standard colours (other colours on request)


The MGM100 meter is produced with multi-camera technology; six metrological complexes of 6 dm3, phased through a special kinematics, work in series/ parallel optimizing stability and accuracy of measurement.

The difference in pressure between the inlet and outlet of the counter induces the filling and cyclic emptying of the two measuring complexes through the alternating movement of the deformable membranes.  

The gas passing through the complexes is collected by a special collector and expelled by an outlet pipe. By means of the measuring kinematics, consisting of drawer valves and crank-rod coupling, the alternative motion is converted into rotary motion. 

By means of a mechanical shaft, the counter dial is activated, which records the measurement in accordance with current regulations.
