Burkert 8746 is a versatile device serving as both a mass flow controller and a meter for gases. It excels in various applications, ranging from metal and glass manufacturing to test benches and filling systems. With its multiple interface options, it seamlessly integrates into existing systems, supporting CANopen, CAN-based büS, PROFIBUS-DP, and analog communication. The integrated configuration memory simplifies device exchange by storing relevant parameters, eliminating the need for software tools.

Type 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 manufactur ing 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 field bus. 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 Ether net 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 character ised 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 explo sion protection.

3.) Max. Ambient temperature for versions with cULus approval is 40 °C
1.2. Version with electromagnetic proportional valve
Type 8746 can be configured as MFC or MFM as required. The MFC version uses direct-acting proportional valves of the 287x series. These electromagnetic proportional valves are normally closed and stand for highest measuring accuracy and repeatability with response times of a few hundred milliseconds.

1.3. Version 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 con sumption of a system. When de-energized, 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 duty cycle of the motor increases drastically due to frequent changes in the setpoint value. More

7. Product operation
7.1. Measuring principle
This sensor works as a hot-film anemometer in the so called CTA operational mode (Constant Temperature Anemometer). To do this, two resistors with precisely specified temperature coefficients located directly in the media flow and three resistors located outside the flow are connected together to form a bridge.
The first resistor in the gas flow (R
T
) measures the fluid temperature, while the second, low value resistor (R is a measure of the heat being removed by the flowing gas, and represents the primary measurement.
S
) 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
An adequate flow conditioning within the MFC and the calibration with high quality flow standards ensure that the mass of gas flow ing per time unit can be derived from the primary signal with high accuracy.

9.1. Bürkert Communicator Software
Note:
To install the software, click here .
Part of Bürkert’s EDIP program (Efficient Device Integration Platform) is the Bürkert Communicator. This software can be run under
MS-Windows and it is available on Bürkert’s website for free. The Bürkert Communicator allows convenient system configuration and parametrisation of all connected field devices. An accessory part, the büS stick serves as the interface between computer and process instruments (see
“10.4. Ordering chart accessories” on page 21 ). It transfers “USB data” to “CAN data”. The Communi
cator allows:
• Diagnosis
• Parametrization
• Registration and storage of process data
• To watch graph of process
• To update firmware of the device connected
• Guided re-calibration
Type 8746 connection with Bürkert Communicator software
The interface to the “Bürkert Communicator” software tool is based on CANopen. The appropriate bus termination is mandatory.
Hence, please activate, for Type 8746 with analogue or PROFIBUS interface, the termination resistor switch on the büS-stick. For
Type 8746 büS / CANopen, this termination resistor should not be activated, in case the device is already integrated in a properly terminated bus network
To connect the MFC / MFM with the “Bürkert Communicator” software tool, you need a büS-stick. The büS-stick sets contain the necessary accessories.
• For Type 8746 büS / CANopen, the connection is made directly via the 5 pin M12 plug (büS-stick Set 1 contains the necessary accessories).
• For Type 8746, with analogue or PROFIBUS, the connection is made via the micro-USB socket on the device (büS-stick Set 2 contains the necessary accessories).
ATTENTION: No external power supply may be connected to the micro-USB socket! The power supply to the unit must be provided
as described in chapter “5. Device/Process connections” on page 17
.

10.2. Recommendation regarding product selection
Note:
The product questionnaire form at the end of this document contains the relevant fluid specification. Using the experience of
Bürkert engineers already in the design phase provide us with a copy of the request containing the necessary data together with your inquiry or order.
For the proper choice of the actuator orifice within the MFC, not only the required maximum flow rate Q ues directly before and after the MFC (p

should be known. In general, these pressures are not the same as the overall inlet and outlet pressures of the whole plant, because usually there are additional flow resistors (tubing, additional shut-off valves, nozzles etc.) present both before and after the controller.
Please use the product questionnaire form at the end of this document to indicate the pressures directly before and after the MFC.
If these are unknown or not accessible to a measurement, estimates are to be made by taking into account the approximate pressure drops over the flow resistors before and after the MFC, respectively, at a flow rate of Q let pressure p
