An air flow rate sensor, integral to engine management systems, measures the velocity and volume of air entering the engine, providing critical data for the ECU to regulate fuel injection. While the term "air flow rate sensor" is often used interchangeably with air flow meters, our products emphasize precision measurement technology, including hot-wire and hot-film sensor designs. Hot-wire sensors calculate air flow by monitoring heated wire cooling rates, while hot-film sensors use planar chips for enhanced reliability. These sensors ensure the ideal air-fuel mixture, boosting fuel efficiency, engine performance, and emission compliance. Compatible with diverse vehicle makes (Japanese, American, German, French, Chinese), our air flow rate sensors undergo rigorous testing for durability and accuracy.
