Product Description
Series GFC Gas Mass Flow Controller – 0–1000 LPM, Model GFC-2145
Engineered for high-flow industrial gas control, the GFC-2145 Mass Flow Controller provides closed-loop regulation from 0–1000 LPM with stable performance across changing temperatures and pressures. Designed around a straight-tube thermal sensor and restrictor element, this controller maintains accuracy while supporting demanding process environments up to 1000 PSI.
Each unit includes a NIST-traceable calibration certificate, making the GFC-2145 suitable for compliance-driven manufacturing, coating lines, vacuum systems, and semiconductor-adjacent processes.

Advanced Control Electronics
The GFC-2145 integrates electromagnetic valve control and PID electronics to maintain continuous flow stability. Operators can set flow locally or remotely using 0–5 VDC or 4–20 mA signals, while the onboard display reports live flow values in engineering units.
Compatible with the GFT2 Flow Totalizer, this model supports batch processing and totalized gas usage monitoring.
