The Burkert 8742 Mass Flow Controller/Meter Type 8742 - Gas Mass Flow Controller (MFC)/Mass Flow Meter (MFM) Type Description: The Burkert 8742 Gas Mass Flow Controller (MFC)/Meter (MFM) is suitable for a variety of applications, such as metal and glass production or processing, fermentation processes, test benches.
or filling systems, and packaging machines.
The The ME43 can transmit internal CANopen-based communication to Industrial Ethernet or fieldbus standards. The Burkert mass flow controller/meter can switch between büs and CANopen communication at any time.
The German-made Burkert 8742 mass flow controller can be configured as an MFM or MFC as needed. The device can store up to four calibration curves.
The thermal MEMS sensor, located directly in the airflow, offers extremely fast response time and maximum measurement accuracy, while maintaining stable calibration over time.
Burkert's direct-acting proportional valves provide exceptional responsiveness as actuators. An integrated PI controller gives the MFC superior control characteristics. Thanks to its high IP protection and explosion-proof rating, the Burkert 8742 gas mass flow controller (MFC)/Burkert mass flow meter (MFM) is particularly suitable for harsh environments.
Burkert 8742 Gas Mass Flow Controller (MFC) Features: Rated flow range: 0.010 lN/min to 160 lN/min; High measurement accuracy and Repeatability with extremely fast response; Durable flow calibration; Memory card configuration simplifies device replacement.
Optional: ATEX Category II 3G/D or USP Category VI, FDA, EC 1935 Compliance Marks.
Burkert 8742 Gas Mass Flow Controller (MFC) Measurement Principle: Measurement recording is performed directly in the bypass channel. A laminar flow element in the main channel generates a necessary pressure differential, allowing a small portion of the flow to enter the bypass channel.
A sensor located there directly detects the mass flow rate by temperature difference.
A silicon chip with a membrane is mounted on the inner wall of the bypass duct for measuring flow. This membrane has a heating resistor and two symmetrical temperature sensors (located upstream and downstream, respectively).
By maintaining the heating resistor at a constant temperature, the voltage difference between the two temperature sensors can be used to measure the mass flow rate of the gas flowing through the chip in the bypass channel.

- Burkert 8742 MFC/MFM Product Accessories 9.1. Bürkert Communicator Software Note: Please click here to install the software. The Bürkert Communicator software is part of the EDIP (Efficient Device Integration Platform) device platform. This MS-Windows based software tool is available free of charge to every user from the Bürkert website. It allows users to easily configure the system and set parameters for all connected field devices. A connection between the PC and the device can be established via a USB adapter (so-called büS drive disk). It can be purchased as an accessory (see "10.4. Accessory Ordering List" on page 23). The Bürkert Communicator software enables: • Diagnostics • Parameter setting • Registering and saving process parameters • Monitoring process parameters graphically • Updating firmware of connected devices • Guided recalibration procedures Connecting the Model 8742 to the Bürkert Communicator software Our software tool, "Bürkert Communicator Software," uses a CANopen-based interface. A corresponding bus termination indicator is required. Therefore, enable the accessible terminating resistor on the büS board drive for Model 8742 devices with analog or PROFIBUS interfaces. For Model 8742 büS/CANopen devices, if the device is already integrated into a normally terminated bus network, this terminating resistor should not be connected. Connecting the MFC/MFM to the "Bürkert Communicator Software" tool requires the büS drive board. The USB büS interface includes the necessary accessories. • Direct connection via a 5-pin M12 connector in Model 8742 büS/CANopen (USB büS interface 1 includes the necessary accessories). interface 2 includes necessary accessories). Note: Do not connect any external power source to the Micro-USB port! The device must be powered as described in section “5. Device/Process Interface” on page

Depending on the MFC's electrical connections, the following device replacement options are provided to the user: • 8742 büS: Device replacement is performed via the configuration provider of the upper-level gateway controller (ME43 or ME63). A Micro-SD card is required in the gateway for this. The MicroSD card can be purchased as an accessory and must be ordered separately. • 8742 Analog or PROFIBUS: A µSIM card is included in the MFC's supply;
- all relevant data is stored on this card. damaged device and insert it into the new device. This will transfer all data from the device to be replaced to the new device. A prerequisite for a successful device replacement is that both devices, the new device and the device to be replaced, have the same device ID.
Plain language sourcing guide for Burkert 8742 mass flow controller/flow meter (Germany)
Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.
Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.
Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.
If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.
Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.
Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.
Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.
Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.
For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.
For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.
For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
