SONOS型流程气体分析器是采用新型测量原理连续工作的分析仪器。当气体流过射流元件时产生声振动，振动频率与气体混合物的声速成比例。浓度变化和频率变化之间存在着单一的关系，根据此关系可以计算出气体组份的浓度。该测量原理已由德国卡尔斯鲁厄核研究中心申请此项发明的专
SONOS process gas analyzer is the use of new measurement principle of continuous operation of analytical instruments. Acoustic vibrations occur when gas flows through the jet element, and the frequency of vibration is proportional to the speed of sound of the gas mixture. There is a single relationship between changes in concentration and changes in frequency, from which the concentration of gas components can be calculated. The measuring principle has been applied for by the German Karlsruhe Nuclear Research Center for this invention
