How Air Flow Meter Works?

A small electrically heated wire (hot wire) is in a hot-wire mass air flow sensor. A temperature sensor measures the temperature of the air near the hot wire.

Mass airflow sensors detect gas, air, and oxygen. The system’s computer monitors Flow rate and volume, which converts this data into measurable signals. Mass airflow sensors play various roles depending on the type of equipment used. Equipment commonly used includes:

  1. Ventilation systems use mass air flow sensors to monitor the patient’s breathing cycle. A processing unit detects and monitors minute ventilation, tidal volume, and flow rate by converting the gas flow into electrical signals. This data will determine any abnormalities.
  2. A mass air flow meter determines the amount of oxygen, air, and nitrous oxide flowing through the patient’s lungs.
  3. Also, it detects anesthetic gas concentrations to administer a safe and effective dose.
  4. A mass air flow sensor monitors and controls oxygen machine air flow rates.

How Air Flow Meter Works?

Heaters and thermal mass flow meters are included in mass air flow sensors. Heat is transferred from the heating source to the thermal sensor when gas flows through the heating source. A value is then calculated based on the energy required to maintain the sensor at the same temperature. To calculate flow, this value is transmitted through a communication interface.

Designs Of Popular Mass Air Flow Sensors

A mass air flow sensor measures frequency in one of two ways:

  1. Sensors for measuring mass airflow. The output voltage of analog sensors is variable.
  2. Sensors for digital mass airflow. Frequency is the output of digital sensors.

Medical equipment must have mass air flow sensors to function accurately and reliably. Our OEM customers can choose from various cost-effective, high-performance mass air flow sensors.
