    Tips: What is a gas flow sensor?

    A gas flow sensor is a device used to measure the flow rate of gases passing through a specific point. It typically employs various principles such as thermal, differential pressure, or ultrasonic methods to determine the gas flow rate accurately. Gas flow sensors are crucial in industrial, medical, and environmental applications for monitoring and controlling gas flow in processes like manufacturing, combustion, HVAC systems, and medical equipment. These sensors are designed to handle different types of gases and can provide real-time data on flow rates, enabling efficient operation and maintenance of systems where precise gas flow management is critical.
