Product Description
Mid-Range Gas Mass Flow Controller for Process Equipment
The Series GFC Model GFC-1143 Gas Mass Flow Controller is engineered for stable, repeatable gas regulation up to 200 L/min, making it an excellent fit for coating chambers, vacuum pump packages, pilot manufacturing skids, and industrial research systems where controlled throughput matters.
A straight-tube thermal sensor paired with a restrictor flow element minimizes sensitivity to upstream pressure changes, while onboard PID electronics continuously modulate the electromagnetic valve to hold setpoints across dynamic operating conditions. Dual analog outputs enable direct PLC or controller integration for automated gas panels and production tooling.
Each controller ships with a NIST-traceable calibration certificate, supporting ISO-driven facilities and regulated manufacturing environments.
