The Type 8741 mass flow controller (MFC)/mass flow meter (MFM) for gases is
suitable for a variety of applications and is available with Industrial Ethernet, analogue
or fieldbus interfaces. The variant with CANopen-based Bürkert Systembus
(büS) is suitable for integration into existing CANopen networks or (in combination
with the Type ME43 fieldbus gateway) for integration into all common industry
standards for Industrial Ethernet and/or fieldbus. The latter option is tailor-made for
applications with many control loops. Up to 32 MFCs/MFMs can be connected to
one fieldbus gateway. Type ME43 transmits the internal CANopen-based communication
to Industrial Ethernet and fieldbus standards. The mass flow controller/
mass flow meter can always switch between büS and CANopen communication.
Type 8741 can be configured as an MFM or an MFC according to demand. Furthermore
a Modbus RTU variant is available as well. Optionally, up to four calibration
curves can be stored in the device. The thermal MEMS sensor is located directly in
the gas stream and therefore achieves very fast response times. As actuator, a
Bürkert direct-acting proportional valve guarantees high response sensitivity.
