Product Description
Industrial Gas Mass Flow Controller for Medium-to-High Flow Systems
The Series GFC Model GFC-1144 Gas Mass Flow Controller is engineered for precise regulation of gas delivery up to 500 L/min, making it ideal for coating systems, vacuum pump skids, process tooling, and research environments that demand dependable flow stability without stepping into full-scale production volumes.
A straight-tube thermal sensor combined with a restrictor flow element reduces sensitivity to pressure fluctuations, while onboard PID electronics continuously modulate the electromagnetic valve to maintain target flow rates through changing loads. Dual analog outputs allow seamless integration into PLC-controlled skids and automated process lines.
Each unit ships with a NIST-traceable calibration certificate, ensuring traceability for quality programs and regulated industrial operations.
