The main advantages of mass flow controllers

1. Flow measurement and control will not be inaccurate due to temperature or pressure fluctuations. For most flow measurement and control systems, it is difficult to avoid system pressure fluctuations and environmental and medium temperature changes. For ordinary flow meters, pressure and temperature fluctuations will cause large errors; for mass flow meters/mass flow controllers, they can generally be ignored. 2. Self-measurement and control 1. Flow measurement and control are not inaccurate due to temperature or pressure fluctuations. For most flow measurement and control systems, it is difficult to avoid system pressure fluctuations and environmental and medium temperature changes. For ordinary flow meters, pressure and temperature fluctuations will cause large errors; for mass flow meters/mass flow controllers, they can generally be ignored. 2. The automatic mass flow meter/mass flow controller for measurement control can output the flow measurement value as a standard electrical signal output. In this way, it is easy to realize the digital display of the flow, automatic measurement of the accumulated flow, automatic data recording, computer management and so on. For mass flow controllers, automatic flow control can also be realized. Usually, the analog MFC/MFM input and output signal is 0~+5V or 4~20mA, and the digital MFC/MFM is also equipped with RS232 or RS485 digital serial communication port, which can be easily connected with the computer for automatic control. 3. Accurate quantitative control of the flow. The mass flow controller can accurately control the given amount of gas, which is particularly useful for the flow control of many processes and the proportional control of different gases. 4. Wide range of application There is a wide range of working pressure, our products can be from vacuum to 10MPa; can be applied to a variety of gas media (including some corrosive gases, such as HCL); have a wide range of flow, our products The minimum flow range can reach 0~5 sccm, and the maximum flow range can reach 0~200 slm. The resolution of the flow display can reach 0.1% of the full scale, the flow control range is 2-100% of the full scale, and the scale ratio is -50:1, so it is widely used in many fields.
