Material Safety Data Sheets of the media to be used in the system (if applicable). Bronkhorst High-Tech B.V. cannot be held liable for any damage resulting from improper or unsafe use, use for other than the intended purpose or use with other media and/or under other conditions than specified on the purchase order.
The analog output and the digital measured value are scaled accordingly. Switching between ranges can be done via the RS232 interface or the fieldbus interface (if applicable), or with a Bronkhorst® readout and control unit (E-8000, BRIGHT).
The mini CORI-FLOW™ comes with all necessary documentation for basic operation and maintenance. Some parts of this manual refer to other documents, most of which can be downloaded from the Bronkhorst website. Calibration certificates, test certificates and material certificates are part of the scope of delivery or can be provided on request.
· Operating temperature · Technical properties (see Model key) Do not hesitate to contact your Bronkhorst representative if properties and ordering details do not match. Operating conditions Test pressure Bronkhorst® instruments are pressure tested to at least 1.5 times the specified working process conditions and outboard leak tested to at least 2 * 10 mbar l/s Helium.
· Tighten connections according to the instructions of the supplier of the fittings. Fittings Bronkhorst® mini CORI-FLOW™ meters/controllers can be fitted with different fitting types (e.g. compression or face-seal). For leak tight installation, follow the guidelines of the supplier of the fittings. Special fitting types are available on request.
When using other cables, cable wire diameters must be sufficient to carry the supply current, and voltage loss must be kept as low as possible. When in doubt, contact your Bronkhorst representative. When connecting the product to other devices, be sure that the integrity of the shielding is not affected; always use shielded cabling for signals and communication and do not use unshielded wire terminals.
Bronkhorst® To ensure proper shielding, connect the cable shielding with the glands before re-installing them to the instrument housing. For instruments with plastic cable glands, use the supplied clamps to connect the shielding to the metal base plate of the wiring terminal box.
Optional fieldbus interface FLOW-BUS FLOW-BUS is a Bronkhorst® designed fieldbus, based on RS485 technology, for digital communication between devices, offering the possibility of host-control by a Windows computer. Characteristics: · Baud rate 187500 (default) or 400000 Baud · +15…24 Vdc supply voltage ·...

Bronkhorst® PROFIBUS DP PROFIBUS DP is a 2-wire, RS485-based industrial data communication standard (fieldbus) which allows automation components (e.g. sensors, actuators and controllers) to exchange information. Consult Instruction manual PROFIBUS DP interface (document no. 9.17.025) for more information about setting up a PROFIBUS DP network.
Bronkhorst® Operation After correct installation and taking all necessary safety precautions, the mini CORI-FLOW™ can be used to measure and/or control the required flow rates. Powering up and powering down · It is recommended to turn on power before applying fluid pressure and to switch off power only after relieving fluid pressure.
Bronkhorst® · To avoid simultaneous heating and cooling of different parts of the instrument, make sure the ambient temperature is as stable and evenly distributed across the environment as possible. · Avoid temperature shocks; heating or cooling should amount to no more than 1 °C per second.
The instrument can always be operated via RS232 through the micro USB service connection in the wiring terminal box, even if it is configured for RS485 operation. Connecting the device with a micro USB to USB2.0 adapter cable to a Windows computer enables RS232 operation with the free Bronkhorst® FlowWare software suite for Windows. See also section Service port.

The zero point of a Bronkhorst® flow meter/controller is factory adjusted at approximately 20 °C and atmospheric pressure, with the instrument positioned upright. If the ambient conditions or mounting orientation are significantly different, zeroing a new instrument is recommended before using it for the first time.
Bronkhorst® 3.8.1 Digital procedure FlowPlot provides an easy way to adjust the zero point of an instrument via RS232; the Auto zero function automatically performs the procedure described here To adjust the zero point using digital communication, set parameter values in the following sequence (see section...
Bronkhorst® Digital parameters Each instrument is controlled internally by a number of digital parameters, most of which can only be accessed using digital communication. Each communication protocol uses its own methods for communicating with instruments and accessing parameters. This section describes the most commonly used parameters for digital operation of the mini CORI-FLOW™. Descriptions are...
