摘要

To measure the flow rate of each gas component in gas mixture, a novel non-contact sensing method is proposed based on spectrum absorption theory. By using the Finite Element Analysis Method (FEAM), the process of the proposed sensing method is simulated, which proves the feasibility of the proposed method. Then, the further numerical analysis results prove that the non-contact flow rate sensing method could identify the flow rates of each gas components in gas mixture with different flow widths and rates. The maximum relative error is demonstrated to be 9.7%.
