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： IN a thermal type flow measurement apparatus, a heating element is disposed in a fluid passage and generates heat by a passage of a current through itself. A first thermal sensitive element is disposed adjacent upstream of the heating element in a direction of fluid flow to be measured. A second thermal sensitive element is disposed adjacent downstream of the heating element in the direction of fluid flow to be measured. The fluid passage is provided with the heating element, the first thermal sensitive element, and the second thermal sensitive element. The fluid passage has an asymmetric structure with respect to the direction of fluid flow.Means for measuring a difference of temperatures is sensed by the first and the second thermal sensitive elements to produce a voltage according to a fluid flow rate. Heat control means for controlling the passage of the current through the heating element so that a sum with weights of respective temperatures sensed by the first and the second thermal sensitive elements reaches a preset value.
