Mass flow controller becomes a new generation of new instrument
The mass flow controller not only has the function of a mass flow meter, but more importantly, the mass flow controller can automatically control the gas flow, that is, the user can set the flow rate as required, and the mass flow controller automatically keeps the flow constant at the set value. On the other hand, even if the system pressure fluctuates or the ambient temperature changes, it will not deviate from the set value. In simple terms, the mass flow controller is a steady flow device, a gas steady flow device that can be manually set or automatically controlled by a computer.
In general, mass flow meters are used when measuring or monitoring only the flow rate; mass flow controllers are used when the flow rate needs to be controlled. For some measurement occasions, both can be used, but the mass flow controller is better. For example, the measurement hole diameter, valve leakage, and workpiece (such as capillary) flow rate mentioned later. The mass flow controller can output the flow measurement as a standard electrical signal. This is very easy to achieve digital display of the flow, automatic measurement of cumulative flow, automatic data recording, computer management and so on. The mass flow controller can accurately control the amount of gas given, which is particularly useful for flow control in many processes, proportional control for different gases, and the like. For most flow measurement and control systems, it is difficult to avoid system pressure fluctuations and temperature changes in the environment and media. For common flowmeters, pressure and temperature fluctuations will cause large errors; for mass flowmeters/mass flow controllers, they are generally negligible.

For mass flow controllers, automatic flow control can also be achieved. The mass flow controller can be easily connected to a computer for automatic control.

Mass flow controllers have a wide range of working pressures. Our products can be used from vacuum up to 10 MPa. Mass flow controllers can be used in many gaseous media (including some corrosive gases such as HCL); mass flow controllers are very wide The range of flow rate, our product zui small flow range up to 0 ~ 5 sccm, zui large flow range up to 0 ~ 200 slm. Nowadays mass flow controllers have been used more and more widely to become a new generation of new instruments.
