AALBORG GFC17A-VADL2-E0-01-N2 Mass Flow Controller Offers

Mass flow controllers designed to indicate and control flow rates of gases. Advanced straight tube sensor combined with flow passage elements constructed of aluminum and brass for non-corrosive gases. Features a Max Pressure Differential of 50 psi (3.4 bar).


  • Zero and span adjustments are accessible from the outside of transmitters
  • Metered gases are divided into two laminar flow paths, one through the primary flow conduit, and the other through a capillary sensor tube
  • Both conduits are designed to ensure laminar flows and there-fore the ratio of their flow rates is constant
  • Two precision temperature sensing windings on the sensor tube are heated, and when flow takes place, gas carries heat from the upstream to the downstream windings
  • Resultant temperature differential is proportional to the change in resistance of the sensor windings
  • Wheatstone bridge design is used to monitor the temperature dependent resistance gradient on the sensor windings which is nearly proportional to the instantaneous rate of flow
  • Output signals of 0 to 5Vdc and 4 to 20mA are generated indicating mass molecular based flow rates of the metered gas
  • The combined gas streams flow through a proportionating electromagnetic valve with an appropriately selected orifice
  • The closed loop control circuit continuously monitors the mass flow
  • output and maintains it at the set flow rate
  • Flow setpoints are controlled either locally or remotely
  • LCD readout built into the top of the transmitters is tilt-able over 90° to provide optimal reading comfort
  • LCD readout is connected to the transducer by a standard modular plug, and is readily removable for remote reading installations
  • Transducers without LCD readout are also available
  • Available with flow ranges from 10 sccm to 1000 l/min
  • Gases are connected by means of 1/4", 3/8" or optional 1/8" compression fittings and 3/4" FNPT fittings
  • Transducer power supply ports are fuse and polarity protected
