The Mass Flow Controller (MFC) / Mass Flow Meter (MFM) Type 8742 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 8742 is available in two variants: The variant with several analogue

or digital (communication) interfaces and the variant with only a CANopen-based

interface. The latter is suitable for integration into existing CANopen networks or -

in combination with the fieldbus gateway Type ME43 - 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. Type ME43 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 8742 can be configured as required as an MFM or MFC. Optionally, up

to four calibration curves can be stored in the device. The thermal MEMS sensor is

located directly in the gas flow and achieves very fast response times and the highest

level of measuring accuracy, with long-term stable calibration. As the actuator,

a Bürkert direct-acting proportional valve guarantees high response sensitivity. The

integrated PI controller ensures excellent control characteristics of the MFC.

Type 8742 is especially designed for use in harsh environments thanks to its high

IP protection class and explosion protection.
