摘要： A thermal air flowmeter having excellent temperature characteristics and improved measurement accuracy. The thermal air flowmeter includes a temperature sensor disposed in a casing of the air flowmeter, a computing unit for correcting a flow rate detection voltage from a measuring element by using the temperature sensor, and a heating temperature control disposed in a temperature control circuit for performing temperature control of a heating resistor to vary a temperature rise of the heating resistor relative to an air temperature depending on the air temperature. Flow rate detection errors of the thermal air flowmeter caused by an overall temperature change and a temperature change on an intake passage wall surface can be corrected simultaneously and a thermal air flowmeter having superior measurement accuracy can be realized.

摘要： A heating resistance flow rate measuring apparatus which can use a power source of an ECU in an automobile without requiring an expensive protective circuit and regulator. Heating of temperature detecting resistors themselves causes temperature changes on the windward and leeward sides, and these temperature changes depend on the amounts of heat generated by the temperature detecting resistors. The amounts of heat generated by the temperature detecting resistors depend on a voltage value of the ECU power source applied to the temperature detecting resistors, and an error is caused in a sensor output depending on a variation in the voltage of the ECU power source. Based on the finding that suppressing the amount of heat generated by the temperature detecting resistors is effective in avoiding the sensor output error caused depending on a variation in the output voltage of the ECU power source, means for suppressing the amount of heat generated by the temperature detecting resistors is disposed.
