CMG Gas Mass Flow Monitor

The CMG series of gas flow monitor with models for natural gas and compressed air are an efficient way to monitor gas usage. The CMG series offers a wide range of functions, such as instantaneous and integrated flow rate indication, and event output and analogue output. In addition to its wide rangeability, the CMG series is available in a variety of models for application to natural gas and air. It also supports air ratio control and energy management of burners.

Features of the CMG Gas Mass Flow Monitor include:

  • Displays instantaneous or totalised flow
  • Low pressure loss making it suitable for a wide range of burner applications

Available outputs include:

  • alarm
  • instantaneous flow
  • totaliser pulse (NPN open collector) and event
  • Face plate colour coded for service: Natural Gas: Yellow; Air: Blue
  • Does not require upstream or downstream straight pipe runs

Other Applications:

  • Measuring the fuel flow to a gas burner
  • Air ratio control
  • Energy management
