Abstract
An air flow rate meter includes a signal detector and a pulse generator. The signal detector is configured to detect that an output signal from the air flow rate detection element has passed a predetermined threshold. The pulse generator generates a pulse signal by using an output signal from the signal detector as a trigger. An output signal from the air flow rate detection element is corrected based on an output of the pulse generator.
