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.
