摘要： A flow rate of air flowing through an air inlet pipe is detected by a heating resistor disposed therein and converted into an electric signal. A digital processing unit carries out calculation to judge whether or not the converted signal coincides with a predetermined temperature value and to correct the converted signal so that the same is caused to coincide with the predetermined value if both the values do not coincide with each other. The corrected signal is used to keep the heating resistor at the predetermined temperature. The digital processing unit is integrated with the air inlet pipe independently of a digital processing unit for engine control.
