Abstract
A kind of hot —wire style gas flow sensor has been designed. Sensing principle of hot —wire style sensor and it’s temperature characteristics and circuit design of front channel are introduced. Computer processing technology and heat balance principle are used.Fluid speed is determined by heat transfer.Temperature and linearity compensation are achieved through data fusion algorithm to get higher accuracy and temperature stability. Result of function is given in the end.
