Gas Flow Controller


Type 8702 - Mass Flow Meter for Gases (MFM)


The mass flow meter (MFM) type 8702 is suited for measuring the mass flow of gases over a big flow range. The thermal MEMS sensor is located directly in the gas stream and therefore reaches very fast response times. Type 8702 can optionally be calibrated for two different gases; the user can switch between these two gases. As electrical interfaces both, analog standard signals and fieldbuses are available. Type 8712 is especially designed for use in harsh environments due to the high protection class.

  • Nominal flow ranges from 0.010 lN/min to 80 lN/min
  • High accuracy
  • Very fast response times
  • Protection class IP 65
  • Optional: Fieldbus interface

Type 8711 - Mass Flow Controller for Gases (MFC)


The mass flow controller (MFC) Type 8711 is suited for regulating the mass flow of gases over a big flow range. The thermal MEMS sensor is located directly in the gas stream and therefore reaches very fast response times. A direct-acting proportional valve from Bürkert guarantees a high sensitivity. The integrated PI controller ensures outstanding control characteristics of the MFC. Type 8711 can optionally be calibrated for two different gases; the user can switch between these two gases. As electrical interfaces both, analog standard signals and fieldbuses are available. The mass flow controller type 8711 fits for various applications, like e.g. burner controls, heat treatment, material coatings, bio reactors, fuel cell technology or test benches.

  • Nominal flow ranges from 0.010 lN/min to 80 lN/min
  • High accuracy and repeatability
  • Very fast settling times
  • Optional: Fieldbus interface

Type 8745 - Mass Flow Controller (MFC)/ Mass Flow Meter (MFM) for gases


The MFC / MFM type 8745 is suitable for the mass flow control of high flow rates. Type 8745 can be configured as MFM or MFC. Optional, four different gases can be calibrated. The thermal inline sensor is located directly in the main gas stream and therefore reaches very fast response times. A direct-acting proportional valve as regulating unit guarantees high sensitivity. The integrated PI controller ensures outstanding control characteristics of the MFC / MFM. MFC Type 8745 is available in two versions: with electromagnetic proportional valve and with motor-driven proportional valve.

  • Nominal flow ranges from 20 lN/min up to 2500 lN/min
  • High accuracy and repeatability
  • Communication via standard signals or Industrial Ethernet
  • Electromagnetic and motor-driven valve actuation available
  • Easy device exchange through configuration memory
