GFC thermal Mass Flow Controller models, designed to indicate and control set flow rates of gases, assure +/- 1% accuracy up to 100 liters. The GFC combines the characteristics, and accuracy of conventional mass flow devices into a unique compact design at low costs previously unattainable. Each of these controllers incorporates an advanced straight tube sensor in conjunction with flow passage elements constructed of aluminum and brass for non-corrosive gases or 316 stainless steel for corrosive applications. Zero and span adjustments are accessible from the outside of transmitters. 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 case of a power outage. Setpoints are controlled either locally or remotely.
