High-performance thermal mass flow meters are devices used to measure the mass flow rate of gases, characterized by high precision, stability, and versatility. Here are some common types of high-performance thermal mass flow meters and their usage:

1. Thermal Mass Flow Meters (TMFMs): Thermal mass flow meters determine mass flow rate by measuring the heat loss of gases passing through a sensor. During usage, TMFMs are typically installed in pipelines where the gas flow heats the sensor. The mass flow rate of the gas is then calculated by measuring the temperature change of the sensor. TMFMs usually come with a digital display or output signal for direct reading or connection to control systems for monitoring and control.

2. Coriolis Mass Flow Meters: Coriolis mass flow meters measure mass flow rate by utilizing the twisting effect of fluids passing through vibrating tubes. During usage, the flow of fluids through the vibrating tubes causes the tubes to vibrate, and the mass flow rate is determined by measuring the frequency and amplitude of the vibration. Coriolis flow meters typically feature a digital display or output signal for direct reading or connection to control systems for monitoring and control.

3. Inline Thermal Mass Flow Meters and Insertion Thermal Mass Flow Meters: Both types of thermal mass flow meters are installed in pipelines. Inline meters are installed directly inside the pipeline, while insertion meters involve inserting sensors into the pipeline. During usage, gases flow through the sensors, and the mass flow rate of the gas is calculated by measuring the temperature change of the sensor. These flow meters also typically feature a digital display or output signal for monitoring and control.

When using high-performance thermal mass flow meters, the following points should be noted:

• Before installation, ensure the selection of the appropriate size and type of flow meter and follow the manufacturer's installation instructions.
• During usage, perform calibration and maintenance according to the specific application to ensure accuracy and stability.
• For applications requiring connection to control systems for automation, ensure proper connection of output signals and configure the control systems as needed.
• Regularly inspect and clean the flow meters to ensure proper operation and extend their service life.

In conclusion, high-performance thermal mass flow meters should be correctly installed, calibrated, and maintained according to the specific model and application to ensure accurate and stable measurement of gas mass flow rate.
