    Bronkhorst® Installation Mounting For stable fixation to a rigid and stable surface or construction, use the threaded mounting holes in the rear of the instrument housing (see product overview). Consult the dimensional drawing for the exact size and locations. 4.1.1 Location Gas bubbles in the liquid can lead to measuring errors.

  • Page 15: Electrical Connections

    The equipment carries the CE-mark and is compliant with the concerning EMC requirements. However, EMC requirements can only be met using appropriate cables and connector/gland assemblies. Bronkhorst recommends the use of their standard cables. These cables have the right connectors and loose ends (if any) are marked to help prevent wrong connection.

    Adjusting zero point Zero-stability The zero point of a Bronkhorst® flow meter/controller (the measurement signal that indicates the absence of a flow) is factory adjusted with water, at approximately 20 °C and atmospheric pressure (ambient conditions), with the instrument positioned upright. Under normal circumstances, the zero point will remain stable. However, in rare cases (for example due to strong fluctuations in temperature and/or pressure), the instrument might develop a zero-stability error over time, causing it to detect a flow when actually there is none.

    Bronkhorst® Digital communication RS-232 communication Digital Bronkhorst® instruments can be monitored and operated via RS-232 using the free FlowWare software tools for Windows. These tools provide a graphical interface to the ProPar protocol, for monitoring and changing instrument parameters. The FlowWare toolkit provides functionality for monitoring and operating digital instruments (FlowPlot, FlowSuite), selection of the active fluid and fieldbus configuration (if applicable).

    Due to limitations in, for example, memory capacity or communication properties, definition files for other fieldbus systems usually do not make all parameters available. For information about parameter access and availability for Bronkhorst® instruments in a specific fieldbus network, consult the according fieldbus manual.

  • Page 36: Maintenance

    Inexpertly servicing instruments can lead to serious personal injury and/or damage to the instrument or the system it is used in. Servicing must therefore be performed by trained and qualified personnel. Contact your Bronkhorst representative for information about cleaning and calibration. Bronkhorst has a trained staff available.

  • Page 37: Troubleshooting And Service

    To track down problems in the fluid system, depressurize the fluid system and disconnect the suspected unit from the process line. Dirt or clogging might be quickly detected by visual inspection on disassembled fluid connections. If you suspect leakage, do not disassemble the device for inspection, but contact your Bronkhorst representative for service or repairs.
