WebTake the GCF of the gas that you are flowing and divide that by the GCF of the gas that the MFC was calibrated for. Example: the MFC is calibrated for 100 sccm of Argon (GCF 1.39) and you are flowing CO2 (GCF = 0.7) the resulting effective GCF would be 0.7/1.39 = 0.50. Therefore the 100 sccm Argon instrument will be flowing 50 sccm of CO2 at ... WebA mass flow meter measures the flow rate of a gas based on the convective transfer of heat on the surface of the flowing gas and uses temperature sensors with electric heaters in …

Mass flow controller - Wikipedia

WebAll Mass Flow Controllers feature an inlet port, outlet port, a mass flow sensor and a proportional control valve. They are fitted with a closed loop control system, which is … WebW = r · Q, which means that the mass flow of fluid passing through a flowmeter (A) is equal to the fluid density (r) times the volume of the fluid (Q). Volumetric flowmeters directly measure the volume of fluid (Q) passing through the flowmeter. The only flowmeter technology that measures volume directly is the positive displacement flowmeter. probuilder cut hole
