SERIES GFC

GAS MASS FLOW CONTROLLERS

FLOW

Flow Range Up to 1000 L/min, Pressures Up to 500 psi, NIST Traceable

5-37/64

Model GFC-1101 thru GFC-1111

The Series GFC Gas Mass Flow Controllers combine a straight tube sensor with a

restrictor ow element. It is available for ow ranges up to 1000 L/min and offered in aluminum or 316 SS in 1/4˝, 3/8˝, 1/2˝ and 3/4˝ sizes.

FEATURES/BENEFITS

• 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 control by comparing measured sensor signal set to ow rates

• Set points can be adjusted with local potentiometers or remotely via 0-5 VDC or 4-20 mA analog signal

Controllers

• Actual gas ow is displayed in engineering units on a 3-1/2 digit, 90° tiltable LCD

Mass Flowmeters/

readout

• Can be used with Series GFT2 Flow Totalizer for applications requiring totalization

• NIST traceable certicate included

APPLICATIONS

• Gas ow measurement

• Gas ow control

• Operating pumps and valves

• Process equipment

• Vacuum processes

• Glass and metal coating

• Film deposition
