Abstract
An air flow measurement device that measures an air flow rate based on an output value of a sensing unit attached in an environment in which air flows, the air flow measurement device is provided. The air flow measurement device may calculate an average air amount, which is an average value of the air flow rate, from the output value. The air flow measurement device may calculate a pulsation maximum value, which is a maximum value of the air flow rate, from the output value.
