• Nominal flow ranges from 20 l/min up to 2500 l/min High measuring accuracy and repeatability with very fast response times Long-term stability of the flow calibration Simpler device exchange due to configuration memory Optional: ATEX II Cat. 3G/D or USP Class VI, FDA, EC 1935 conformity 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 inter- face. The latter is suitable for integration in existing CANopen networks or - in combination with a Bürkert fieldbus gateway - for integration in all common indus- try standards for Industrial Ethernet or fieldbus. This variant is tailor-made for appli- cations with many control loops. Up to 32 MFCs / MFMs can be connected to one fieldbus gateway. The gateway transmits the internal CANopen-based communi- cation to Industrial Ethernet and fieldbus standards. The mass flow controller / mass flow meter can always be switched between büS and CANopen communica- tion. 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 environ- ments thanks to its high IP protection class and explosion protection. Product variants described in the data sheet may differ from the product presentation and description. Type description Can be combined with Type 8746 © Christian Bürkert GmbH & Co.

Information in relation to the typical power consumption (at + °C ambient temperature, nominal flow and 30 min closed-loop control mode). Information according to UL 61010 may vary (see operating instructions Type 8746 ). 1.3. Variant with electromotive proportional valve Type 8746 with electromotive proportional valve is especially suitable for applications with high inlet pressures up to 22 bar or high flow rates (with low pressure loss). Thanks to their very low holding capacity, these valves can drastically reduce the less energy consumption of a system. When de-energised, the motor valves remain in position. The maximum duty cycle of the motor depends on the ambient temperature. The duty cycle is not the duty cycle of the appliance but the duty cycle of the motor. This is only switched on when the valve is to move. The motor’s duty cycle increases drastically due to frequent changes in the setpoint value.

Measuring principle This sensor works as a hot-film anemometer in the so called CTA operational mode (Constant Temperature Anemometer). 2 resistors with precisely specified temperature coefficients are located directly in the media flow. 3 resistors are located outside the flow. All resistors are connected to form a bridge. The first resistor in the gas flow (RT) measures the fluid temperature, while the second, low value resistor (RS) is heated so that it is maintained at a fixed, predefined overtemperature with respect to the fluid temperature. The heating current required to maintain this temperature is a measure of the heat being removed by the flowing gas and represents the primary measurement. An adequate flow conditioning within the MFC and the calibration with high quality flow standards ensure that the mass of gas flowing per time unit can be derived from the primary signal with high accuracy.

mechanical stress.

4 The screws prevent loosening of the protection cap and

hence the M12 connection under tensile stress.

5 The protection cap prevents damage of the M12 plug and all

connected elements if mechanical stress is applied. No particular ATEX sockets are required.

Bürkert Communicator software Note: The corresponding communication software can be downloaded from the website Type 8920 The Bürkert Communicator is the most important software component of the EDIP (Efficient Device Integration Platform). Various features of this universal tool simplify the configuration and parametrisation of devices equipped with a digital CANopen-based interface. With this tool, the user has a complete overview of cyclic process values as well as acyclic diagnostic data. The integrated graphical programming environment enables the creation of decentralised sub-system control functions. The connection to the PC is established with a USB büS interface set. The adapter is available as an accessory (see “10.5. Ordering chart accessories” on page 37 The Bürkert Communicator enables: Configuration, parametrisation and diagnosis of EDIP devices / networks Switching between defined gases Easy and comfortable mapping of cyclic values Graphic display, monitoring and storage of process values Firmware update of the connected EDIP devices Saving and restoring device configurations Zero-point adjustment in case of changed ambient conditions Guided re-calibration routine

For Type 8746 Analogue, Industrial Ethernet or PROFIBUS-DP, activate the termination resistor switch on the büS stick. For Type 8746 büS/CANopen, the termination resistor must not be activated in case the device is already integrated in a properly terminated bus network. For Type 8746 Analogue, Industrial Ethernet or PROFIBUS-DP, the connection is established via the micro USB socket on the device (USB büS interface set 2 contains the required accessories). For Type 8746 büS/CANopen, the connection is established via the 5-pin M12 plug (USB büS interface set 1 contains the required accessories). Please note: no external power supply must be connected to the micro USB socket. The device must be provided with power as described in chapter “5. Device/Process connections” on page 30 9.3. Configuration management for easy device replacement Depending on the electrical connection of the MFC, the following options for device replacement are available: If a device needs to be replaced, the memory card can be removed from the defective device and inserted into the new one. This transfers all data of the device to be replaced to the new device. The memory card is available as an accessory and must be ordered separately (see “10.5. Ordering chart accessories” on page 37) Option for Type 8746 büS/CANopen: The device is exchanged via the configuration provider of the higher-level gateway control (ME43 or ME63). In the gateway, a memory card is required. The memory card is available as an accessory and must be ordered separately (see “10.5. Ordering chart accessories” on page 37) In order to successfully exchange the device, it is necessary that both the new device and the device to be replaced possess the same device ID. 9.4. Web server for Industrial Ethernet variant The Industrial Ethernet-based devices (except for the EtherCAT® protocol) from software version A.13.00.00 dispose of an integrated web 10.

Bürkert Product Enquiry Form” on page 37 ) for the device details and send it to us once completed. For the proper choice of the actuator orifice within the MFC, you need to know not only the required maximum flow rate Qnom but also the pressure values directly before and after the MFC (p1, p2) at Qnom. In general, these pressures are not the same as the overall inlet and outlet pressures of the whole plant, because usually, additional flow resistors (tubing, additional shut-off valves, nozzles etc.) are present both before and after the MFC. Please use the Product Enquiry Form to indicate the pressures directly before and after the MFC. If these are unknown or not accessible to measurement, estimates are to be made by taking into account the approximate pressure drops over the flow resistors before and after the MFC, at Qnomflow rate. In addition, please quote the maximum inlet pressure p1 max to be encountered. This data is needed to make sure the actuator is able to provide a close-tight function within all the specified modes of operation.
