What Is the Function of Air Flow Meter Sensor

The function of an air flow meter sensor is to measure the amount of air entering the engine of a vehicle or a process in an industrial setting.

This measurement is crucial for ensuring the proper air-to-fuel ratio for combustion engines, as well as for controlling various processes reliant on airflow in industrial machinery.

In automotive applications, the air flow meter sensor provides data to the engine control unit (ECU), allowing it to adjust fuel injection rates accordingly.

By maintaining the correct air-to-fuel ratio, the sensor helps optimize engine performance, fuel efficiency, and emissions levels.

In industrial settings, air flow meter sensors are used to monitor and regulate airflow in processes such as HVAC systems, pneumatic systems, and combustion processes.

They ensure that the correct volume of air is supplied to achieve desired outcomes, such as maintaining temperature control, facilitating material transport, or supporting combustion reactions.

Overall, the function of an air flow meter sensor is critical for achieving optimal performance, efficiency, and environmental compliance in both automotive and industrial applications. 

Working Principle of Air Flow Meter

Different air flow meters use different working principles, mainly the following types:
1. Vane Airflow Sensor: This sensor has a rotating vane. When air flows through, it will push the vane to rotate. The change in the position of the vane will change the resistance value, thereby generating an electrical signal proportional to the air flow.
2. Hot-Wire Airflow Sensor: Use a heated metal wire. When air flows through, the temperature of the metal wire will drop. The ECU will increase the current to maintain the temperature of the metal wire. The change in current reflects the change in air flow.
3. Hot-Film Airflow Sensor: Similar to the hot-wire type, but uses a thin film resistor instead of a metal wire.
4. Karman Vortex Airflow Sensor: Use the vortex generated when air flows through an obstacle. The frequency of the vortex is proportional to the air flow. The sensor measures the air flow by detecting the vortex frequency.
5. Ultrasonic Airflow Sensor: Using ultrasonic transmitter and receiver, air flow will affect the propagation time of ultrasonic waves, so that the air flow can be calculated.
