The Type 8743 mass flow controller (MFC)/meter (MFM) is suitable for controlling

or measuring aggressive gases, gas mixtures and in the area of application for

alternating gases. A thermal capillary sensor, with sensor elements not in contact

with medium, is used for this. This also enables easy conversion to the process gas

in question. The forms in contact with medium are made of high-quality stainless

steel and FFKM as a seal material for high chemical resistance. The MFC version

achieves high control accuracy thanks to the use of Bürkert proportional valve

technology and the application-appropriate layout of the valve orifice. The MFC

can be implemented with low pressure loss as required, due to the diversity of the

available valve orifices. These MFCs and MFMs either communicate the set-point

and actual values of the flow value via an analogue interface, or other values, as

well as the set-point and actual values, that can be selected via software via an

Ethernet interface. Type 8744 represents the IP65 variant of the Type 8743 and

contains the CAN-based büS version for integration into CAN or büS networks. A

wide range of devices can easily and efficiently be integrated into the control level

in this way via an Ethernet gateway. The communication data is configured via the

Bürkert Communicator software.
