Model GFC thermal Mass Flow Controllers are designed to indicate and control set flow rates of gases.
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 "U"-shape 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.

Application
For flow meters and controllers with analog 0-5 Vdc, 5-10 Vdc, 0-10 Vdc, 4-20mA input output interface, where flow indications / control and totalizers or alarm functions are required. Also when re-transmission of the flow rate and/or totalizer functions via optically-isolated pulse output or serial communication is desired. Local or programmable set point control for flow controllers (no host PC presence required). Activation of user-supplied equipment via programmable optically-isolated digital outputs when flow alarms or totalizers events are active.
