Large-Flow Type Micro Insertion Airflow Thermal Mass Air Flow Meter Sensor
Thermal gas mass flowmeters are a type of mass flowmeter specifically designed for measuring the flow rate of gases, while mass flowmeters, in a broader sense, can measure the flow rate of both gases and liquids. Here are some key differences between thermal gas mass flowmeters and other types of mass flowmeters:
Operating Principle:
Thermal Gas Mass Flowmeters: These flowmeters operate based on the principle of convective heat transfer. They typically have a heated sensor and a temperature sensor. As gas flows past the heated sensor, it absorbs heat, and the temperature sensor measures the temperature change. The amount of heat absorbed is proportional to the mass flow rate of the gas.
Other Mass Flowmeters: Other types of mass flowmeters may use different operating principles such as Coriolis, differential pressure, or ultrasonic methods to measure mass flow. These methods are suitable for measuring the flow of both gases and liquids.
Fluid Compatibility:
Thermal Gas Mass Flowmeters: These flowmeters are specifically designed for measuring the flow of gases and may not be suitable for measuring liquids.
Other Mass Flowmeters: Mass flowmeters using other principles may be suitable for measuring both gases and liquids, depending on their design and specifications.
Measurement Range:
Thermal Gas Mass Flowmeters: Typically used for measuring gas flow rates, thermal gas mass flowmeters have a specified measurement range suitable for gas flow applications.
Other Mass Flowmeters: Depending on the type and design, other mass flowmeters may have a wider range of applications, capable of measuring both gas and liquid flow rates over a broader range.
Fluid Properties:
Thermal Gas Mass Flowmeters: These flowmeters are designed to measure the flow of gases with varying properties such as density, viscosity, and composition.
Other Mass Flowmeters: Mass flowmeters using different principles may have different sensitivities to fluid properties. Some may be more suitable for certain types of fluids or applications.
Installation and Maintenance:
Thermal Gas Mass Flowmeters: Installation and maintenance procedures for thermal gas mass flowmeters may differ from other types of mass flowmeters due to their specific design and operating principles.
Other Mass Flowmeters: Installation and maintenance requirements may vary depending on the type of mass flowmeter being used and its application.
In summary, while thermal gas mass flowmeters are a type of mass flowmeter specifically designed for gas flow applications, other types of mass flowmeters are more versatile and can measure the flow of both gases and liquids using different operating principles. The choice between thermal gas mass flowmeters and other mass flowmeters depends on the specific application requirements, fluid properties, and measurement range needed.
