GF80 Series

GF80 Series Metal Sealed Thermal Mass Flow Controllers & Meters

Raises the standard in performance for value-driven metal sealed applications.

Models GF80

For many industrial and semiconductor processes, both performance and cost efficiency are crucial. The GF80 Series metal sealed mass flow controllers and meters deliver both: Engineered using the same fast response sensor and patented 4th generation MultiFlo™ technology as our best-selling GF100 series, it’s the right choice for operations that need high performance at a value price point. Moving to a metal sealed MFC brings the full benefit of MultiFloTM multi-gas/multi-range capability since there are no limitations in gases that can be used, enhanced purity of the gas due to elimination of oxygen permeation through elastomers, and a reduction in maintenance since metal seals will last indefinitely.


  • Long-term zero stability of <±0.5% full scale per year
  • <1 second settling times
  • Full-scale flow rates up to 300 slpm
  • All-metal seal flow path – 16µ inch Ra surface finish
  • Corrosion-resistant Hastelloy® sensor can operate at lower temperatures for gases prone to thermal decomposition
  • Programmable MultiFloTM capability—one device, thousands of gas types and range combinations without removing the MFC from the gas line or compromising accuracy
  • Best-in-class temperature coefficient specification through active temperature compensation
  • Embedded self-test routines and independent diagnostic/service port
  • Slimline body with VCR fittings
  • DeviceNetTM, Profibus®, RS-485 and analog interfaces
  • Fast <1 second flow settling time eliminates wasted gas and process variability
  • No elastomer seals that can have oxygen permeation, requiring replacement over time
  • MultiFloTM simplifies and streamlines changing process gases — no more removing and calibrating MFCs
  • New gases and/or ranges can be set in under 60 seconds
  • Measurement accuracy not affected by temperature variations
  • Convenient access to diagnostics port for maximum uptime
  • Compact size eases integration into tight machine spaces; excellent choice for retrofits
  • Multi-protocol communication interface simplifies integration into existing systems
Key Applications
  • Cost efficient retrofit/upgrade of legacy MFCs in refurbished semiconductor process tools
  • Reduce MFC inventory in six-inch/eight-inch semiconductor fabs
  • MOCVD for LED and power device manufacturing
  • Solar/thin film chemical vapor deposition (CVD) systems
  • Analytical OEM equipment
