Gas Flow Meter: CMG Series 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 analog 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.
Available in both US and metric unit display, the GMG is a Flow Meter designed to measure the fuel flow to a gas burner. It's sensing element is the MicroFlow sensor chip, a MEMS thermal mass-flow sensor. The CMG displays instantaneous or totalized flow.
