The mass flow controller (MFC) / mass flow meter (MFM) Type 8746 for gases is
suitable for a wide range of applications, e.g. metal and glass manufacturing or
processing, fermentation processes, test benches or filling systems and packaging
machines. Type 8746 is available in two variants: A variant with several analogue or
digital (communication) interfaces and a variant with a pure CANopen-based interface.
The latter is suitable for integration in existing CANopen networks or - in
combination with a Bürkert fieldbus gateway - for integration in all common industry
standards for Industrial Ethernet or fieldbus. This variant is tailor-made for applications
with many control loops. Up to 32 MFCs / MFMs can be connected to one
fieldbus gateway. The gateway transmits the internal CANopen-based communication
to Industrial Ethernet and fieldbus standards. The mass flow controller /
mass flow meter can always be switched between büS and CANopen communication.
Type 8746 can be configured as an MFM or an MFC according to demand.
Optionally, up to four calibration curves can be stored in the device. The thermal
inline sensor is located directly in the main flow and achieves fast response times
and a high level of measuring accuracy with long-term stable calibration. As the
actuator, a Bürkert direct-acting, electromagnetic proportional valve or motor valve
guarantees high response sensitivity. The integrated PI controller ensures excellent
control characteristics of the MFC. Type 8746 is characterised by low pressure
drop, even at high flow rates, and is especially designed for use in harsh environments
thanks to its high IP protection class and explosion protection.
