Abstract: Based on the acoustic decay theory, this paper introduced the method adopting ultrasonic mixed-gas monitoring. A kind of monitoring device was designed with the ultrasonic sensors measuring carbon-containing gases in air. The monitoring device was composed of the lower computer, the measuring module and the upper computer, the monitoring module of ultrasonic monitoring model. Each submodule was connected, debugged, and carried out experimental measurement. The experimental data and theoretical data were consistent with each other, which realizes monitoring the component and concentration of the carbon-containing gas in air.
Key words: ultrasonic; acoustic decay; gas monitoring; sensor
