Compact, self-contained GFC mass flow controllers are designed to indicate and control flow rates of gases. The rugged design coupled with instrumentation grade accuracy provides versatile and economical means of flow control. The built-in electromagnetic valve allows the flow to be set to any desired flow rate within the range of the particular model. The valve is normally closed as a safety feature to ensure that gas flow is shut off in the case of a power outage. The LCD readout built into the top of the transducer is tiltable over 90 degrees to provide optimal reading comfort. GFC mass flow controllers are available with flow ranges from 10 sccm to 2000 mL/min (N2). Gases are connected by means of 1/4” compression fittings. These controllers may be used as benchtop units or mounted by means of screws in the base. Transducer power supply ports are fuse and polarity protected.

For the use of other type gasses, please refer to the gas coefficient conversion table, which is listed in the operation manual. For liability considerations, at MTI does not endorse or recommend any product for a given gas, corrosive or otherwise. Our obligation is to list all construction materials in fluid contact, and customer’s responsibility For different gases, DuPont publishes compatibility information, see: https://dupont.secure.force.com/CRG_Home How to connect an MFC to a tube furnace
