20 – (+5) = 15 PSID The 5 PSIG backpressure will try to reduce the gas flow through the controller. This 15 PSID pressure will force considerably less gas through a given orifice than would the 35 PSID pressure. The MFC valve is a variable orifice and the orifice varies in size depending on the flow rate, density, viscosity, and pressure.

MC-Series Mass Flow Controllers rapidly reach setpoints to maintain stable control of mass flow, volumetric flow, or pressure for 98+ gases from 0.01% to 100% of full scale. CODA KC-Series Coriolis Mass Flow Controllers control gas or liquid flows even when the fluid composition is changing or unknown, for pressures up to 4,000 PSIA (275 barA).

A traditional P-MFC approach includes an upstream pressure transducer, an upstream control valve, two individual pressure transducers, and laminar flow element. The use of an upstream valve has

Oct 26,  · HATFIELD, Pa. (USA) October 26, - Brooks Instrument, a world leader in advanced flow, pressure, vacuum and vapor delivery solutions, will feature its new GP200 Series pressure-based mass flow controller (P-MFC) at SEMICON Europa, November 16-19, in Munich, Germany. The company will be exhibiting in booth B1572.

The pressure based MFC was introduced in the last decade and is now overtaking the use of the thermal MFC in critical etch applications. In 2002, Fugasity introduced a pressure base MFC called the

A robust product portfolio consisting of SAM and Aera brand analog, digital, and pressure insensitive MFCs provide leading edge Mass Flow Control 

A mass flow controller (MFC) has a standard envelope with an enclosure and a corresponding base. A pressure transducer is communicatively coupled to a process gas in a proportional inlet valve without being physically coupled to the base. The space formerly occupied by the pressure transducer is available for additional component integration, or reduction of the standard envelope size.
