    Product description

    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.
