Bürkert Type 8741 and 8745 mass flow meters and controllers

Bürkert has released high-precision mass flow meters (MFM) and controllers (MFC) for gases. The devices feature an integrated industrial Ethernet switch and support all standard industrial Ethernet protocols.

Typical applications for mass flow meters and controllers are in the areas of metal, glass or ceramic processing, coating technology, or the production of foams in the food and plastics industries. MFCs/MFMs are also used in fermenters and water treatment systems.

The Type 8741 flow meters and controllers handle nominal flow rates of up to 150 ln/min (relative to N2), while the Type 8745 devices permit a maximum of 2500 ln/min (relative to N2). Due to their wide measuring range, the same MFC/MFM devices can often be used at different locations within an application, thus reducing the number of device versions.

The mass flow controllers employ direct-acting proportional valves. The Type 8745 can also be combined with a Type 3280 or 3285 motor-driven valve for high-pressure applications of up to 22 bar. Valve orifices up to DN20 can be realised for applications with high flow rates, even at low differential pressures such as those found in burner control systems. All MFC/MFMs are also available with UL approval. In addition to industrial Ethernet interfaces supporting Profinet, EtherNet/IP, EtherCAT or Modbus TCP, standard signal interfaces will soon also be available for Types 8741 and 8745, thereby further expanding the application spectrum.
