ABSTRACT:
An air flow rate meter for detecting an air flow rate in a wide operating temperature range. A heating temperature of a heat generating resistor for detecting an intake air flow rate is set on the basis of an intake air temperature or a current flowing through the heat generating resistor. The heating temperature of the heat generating resistor is kept at an optimum value determined from a look up table stored in a read only memory.
