Gas concentration measurement with thermal flow sensors
, the heating value of the gas is of interest in gas metering. In gas burner appliances, the flame is optimized for efficiency and emission by controlling the mixing ratio of air and gas depending on the gas type. Generally, there is a need for exact gas concentration measurement in many gas handling
