A measurement control device includes a sensing unit and a low-pass filter unit. The sensing unit outputs an air flow rate value corresponding to an air flow rate flowing through a flow path. The low-pass filter unit removes high-frequency components included in the air flow rate value input from the sensing unit. The measurement control device calculates a pulsation state that is a state of a pulsation occurring in the air flow rate based on the air flow rate value that has passed through the low-pass filter unit. The measurement control device corrects the air flow rate value using the pulsation state.
