Dwyer GFC Series Gas Mass Flow Meter and Controllers

Dwyer GFC Series Gas Mass Flow Meter and 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. Flow Range Up to 1000 L/min, Pressures Up to 1000 psi, NIST Traceable.

Dwyer GFC Series Gas Mass Flow Meter and Controllers

Dwyer GFC Series Features

• 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 flow rates
• Set points can be adjusted with local potentiometers or remotely via 0 to 5 VDC or 4 to 20 mA analog signal
• Actual gas flow is displayed in engineering units on a 3-1/2 digit, 90° tiltable LCD readout
• Can be used with Series GFT2 Flow Totalizer for applications requiring totalization
• NIST traceable certificate included
  
  

Application

• Gas flow measurement
• Gas flow control
• Operating pumps and valves
• Process equipment
• Vacuum processes
• Glass and metal coating
• Film deposition
