Brooks Instrument unveils new MFCs Brooks Instrument, a provider of advanced flow, pressure, vacuum and level solutions, has expanded its GF 40/80 Series portfolio of thermal mass flow controllers (MFCs) to enable a broader range of applications. The new GF81 MFC can be used for gas flow rates up to 300 slpm, making it ideal for high-flow applications in thin film, solar, analytical, biotech and fuel cell. The GF81 provides the same high-stability sensor and best-in-class repeatability as the GF40/80 Series, but with a higher flow rate. Compared with competitive products offering a similar flow rate, the compact footprint and low power draw of the GF81 allows users to design smaller, more efficient systems. It also provides better actual process gas accuracy over devices that use traditional single-point conversion factors. The GF81 Series features an all-metal seal flow path for durability and high leak integrity, precise flow control with fast sub-1-second settling times, and 1% of reading accuracy to ensure reliable flow measurement and control in demanding gas flow applications. A wide range of digital and analog I/O options offers the broadest range of communication protocols, making the GF81 an ideal upgrade for existing MFCs or MFMs.
