An air flow metre, synonymous with an air flow meter, is a critical component in automotive systems, designed to measure the volume or mass of air entering the engine, typically in grams per second (g/s). This data is essential for the Engine Control Unit (ECU) to calculate the precise fuel injection amount, based on the air-fuel ratio (air mass flow × air-fuel ratio = fuel mass). Our company offers two main types: hot-wire air flow metres, which determine air velocity by the cooling rate of a heated filament, and hot-film air flow metres, which use a planar hot-film chip for enhanced reliability. These metres ensure optimal combustion, improving fuel efficiency, engine performance, and emission control.
