The CMG series of gas flow meters employ our proprietary Micro Flow thermal flow rate sensor as the sensing element to measure the air and fuel flow rate for gas burners. The CMG flow meter measures the volumetric flow rate in a normal standard state and displays the instantaneous flow rate and the integrated flow total without the need for temperature and pressure conversion. Other functions include alarm contact output, analog output of instantaneous flow rate, and open collector output of integrated pulse or event output. These functions enable fine air-fuel ratio management of individual burners and flow rate management of combustion equipment.
