for gases is intended for the use in a büS or CANopen network. The büS network technology is based on CAN physics and was developed by Bürkert especially for Industrial Ethernet or fieldbus communication in applications with multiple control loops. In combination with the system control unit (SCU) Type ME2X, the CANopen based communication can be translated to the customer’s fieldbus. The mass flow controller (MFC) / meter (MFM) can always be switched between büS and CANopen communication. Given that, Type 8746 can also be directly integrated into existing CANopen networks. Type 8746 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. Type 8746 is especially designed for use in harsh environments due to a low sensitivity to contamination, high protection class and explosion-proof. MFC Type 8746 is available in two versions: With electromagnetic or with motor-driven proportional valve.

• Nominal flow ranges from 20 lN/min up to 2500 lN/min
• High accuracy and repeatability
• Communication via fieldbus based on CANopen
• Optional: ATEX II Cat. 3G/D
• Electromagnetic and motor-driven valve actuation available
