How mass flow controller works
WebThe Valve. The mass flow controller valve is made up of: a motive force (electromagnetic, thermal, piezo-electric, motor-driven etc.) a resistive force (spring, diaphragm, etc.) a variable flow restriction (orifice-poppet, orifice-ball,etc.) The motive force is activated by the control circuitry to act against the resistive force to vary the ...

WebThermal mass flow meters, also known as thermal dispersion or immersible mass flow meters, comprise a family of instruments for the measurement of the total mass flow rate of a fluid, primarily gases, flowing through closed conduits.A second type is the capillary-tube type of thermal mass flow meter. Many mass flow controllers (MFC) which combine a … WebMass flow controllers are used in a wide range of industrial applications when the accurate flow control rate is required. How does a Flow Controller work? The medium enters from the inlet and flows through the sensor or the bypass. The sensor then detects the mass flow rate as a relative change in temperature and converted to an electric signal.
WebJun 28, 2012 · Mass flow controllers are often used to supply inert and other gases into semiconductor processes and laboratory reactors, as shown in Figure 2. In order to calibrate these devices precisely, it is accepted good practice to control the outlet pressure of the devices in the same range as the application pressure.
