Airflow Meter An airflow meter is a device used to measure the volume of air flowing through an engine's intake system in automobiles and other internal combustion engines. This measurement is crucial for maintaining optimal fuel-air mixture and ensuring proper engine performance. The airflow meter reads the incoming air, sends the data to the engine control unit (ECU), which then calculates the correct amount of fuel to be injected into the engine based on the airflow rate.
