    摘要: An air flow meter which can decrease the error due to the backflow. Throttle valve 17 which opens and shuts the air intake passage is installed in the air intake passage of the internal combustion engine. The first sensor part 161 is installed in the air intake passage in the upstream of throttle valve 17. Further, the second sensor part 141 is installed in the air intake passage in the downstream of throttle valve 17. Pulsation compensating means 671 corrects the pulsation of the air flow rate signal detected by the first sensor part by using the output signals of the first and the second sensor parts 161, 141 based on each cylinder of the internal combustion engine.
