If you are planning to use the product (including any third party components supplied by Bronkhorst, such as pumps or valves) with other media and/or other conditions, always be sure to check the wetted materials (including seals) for compatibility. See the technical specifications of the product and consult third party documentation (if applicable) to check the incorporated materials. -

Bronkhorst® Model key The model key on the product label contains information about the technical properties of the instrument as ordered. The specific properties can be retrieved with the diagram below. See section Customized I/O options (pin 5) for more information about the pin-5 configuration options. -
Page 10: Starting Up
The EL-FLOW® Prestige is fitted with specific sealing material(s), compatible with the media specified at ordering time. Be sure that the sealing materials are compatible with the media and conditions used in the system. Bronkhorst High-Tech B.V. cannot be held responsible for any damage resulting from the use of other media and/or conditions than specified on the purchase order. -
Page 11: Mounting
However, compliance with the EMC requirements is not possible without the use of proper cables and connector/gland assemblies. Bronkhorst recommends the use of their standard cables. These cables have the right connectors and if loose ends are used, these are marked to help prevent wrong connection. When using other cables, cable wire diameters should be sufficient to carry the supply current, and voltage loss must be kept as low as possible. -

E-8000. Connecting the instrument with an RS232 cable or an RS232 cable with a USB to RS232 converter to a PC enables the use of the (free) Bronkhorst® FlowWare software for Windows, such as FlowDDE and FlowPlot. Make sure that the instrument label indicates RS232 settings for the 9-pin sub-D connector and apply the proper baud rate settings. -

With FlowTune™ fixed fluid properties for any gas or mixture can be stored in the instrument (density, heat capacity, thermal conductivity and dynamic viscosity). Although custom fluid data can be used, Bronkhorst advises to use the FLUIDAT® on the Net website for calculation of fluid properties at the actual process conditions. FLUIDAT® is a collection of routines to calculate physical properties of gases and liquids. -

Bronkhorst® 3.5.1 Cabling The illustrations below show examples of a number of EL-FLOW® Prestige instruments in an RS485 bus system. Note that many other bus configurations are possible, contact your local sales representative for more information. Please check the total power consumption of your instruments and do not exceed the maximum power of the power supply. -
Page 23: Software
When using a Windows computer to communicate with EL-FLOW® Prestige instruments, only the FLOW-BUS protocol is supported by Bronkhorst® software. When using Modbus operation, software from third parties, such as LabVIEW, ModScan or a Modbus PLC must be used to serve as Modbus master. -

Changing EtherCAT® Second Address EtherCAT® supports the use of a Second Address. Bronkhorst® instruments have 3 rotary switches, with which a Second Address can be set in the range of 0 – 4095 (0xFFF). This value of the rotary switches will be copied to the Configured Station Alias register (address 0x0012:0x0013) at instrument start-up. -
