Gas mass flow controller | range 0-100 LPM. Specified flow range is for an equivalent flow of nitrogen at 70°F (21°C) @ 760 mm Hg | 3/8" compression fitting.
Series GFC Gas Mass Flow Controllers
Flow Range Up to 1000 L/min, Pressures Up to 1000 psi, NIST Traceable
The Series GFC Gas Mass Flow Controllers combine a straight tube sensor with a restrictor flow element. It is available for flow ranges up to 1000 L/min and offered in aluminum or 316 SS in 1/4", 3/8", 1/2" and 3/4" sizes.
Product Applications
- Gas flow measurement
- Gas flow control
- Operating pumps and valves
- Process equipment
- Vacuum processes
- Glass and metal coating
- Film depostition
- Provides high accuracy and repeatability
- Flow rates are virtually unaffected by temperature and pressure variations
- Utilizes an electromagnetic valve and PID electronics to maintain continuous controlby comparing measured sensor signal set to flow rates
- Set points can be adjusted with local potentiometers or remotely via 0 to 5 VDC or 4to 20 mA analog signal
- Actual gas flow is displayed in engineering units on a 3-1/2 digit, 90° tiltable LCDreadout
- Can be used with Series GFT2 Flow Totalizer for applications requiring totalization
- NIST traceable certificate included
