Abstract
The hot wire type air flow meter is an important tool in measuring the quality of air flow. It is widely used in Santana engine, and in this article, the application in exhaust analyzer is introduced. The basis theory, the basic principle and the application of the hot wire type air flow meter are presented. The main purpose of this article is using the least square method to fit the standard data, calibrating accurately the flow meter by making the curve fit, then using standard tests and comparing the results with the standard current flux at last. The results indicate that the hot wire type air flow meter is accurate in surveying the flux of the exhaust gas.
