Page 7: Introduction
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 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. -
Page 8: Product Overview
Switching between ranges can be done via the RS-232 interface or the fieldbus interface, or with a Bronkhorst® readout and control unit (E-8000, BRIGHT). For RS-232 communication, Bronkhorst can offer a special T-part RS-232 cable to connect the instrument with a Windows computer, together with free tooling software (FlowPlot). -
Page 9: Calibration
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 18: Valve Safe State
Bronkhorst® Valve Safe State When a controlling instrument is not powered or cannot communicate with the fieldbus network (if applicable), all electrical valves operated by the instrument (whether integrated or external) automatically return to their default state. The default state is closed for 'normally closed' valves (n/c) and fully open for 'normally open' valves (n/o). Taking into account the typical process conditions under which the instrument is used (such as the processed media and ambient conditions;... -

Page 24: Analog Operation
3.9.2.1 FlowDDE Digital Bronkhorst® instruments can be operated via RS-232 using the Bronkhorst® FlowDDE server application. Dynamic Data Exchange (DDE) provides a basic level of inter process communication between Windows applications. Together with a client application, either self-made or with a third party SCADA program, it is possible to create an easy way of data exchange between the flow meter/controller and a Windows application. -

Page 26: Fieldbus Operation
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 at approximately 20 °C and atmospheric pressure (ambient conditions), with the instrument positioned upright. Under normal circumstances (i.e. when process conditions are constant), the zero point will remain stable. However, several factors might cause the instrument to develop a zero-stability error over time, causing it to detect a flow when actually there is none. -
Page 27: 3.10.1 Manual Procedure
· digitally (via RS-232 or fieldbus) · with the autozero function of a Bronkhorst® readout and control unit (E-8000, BRIGHT) Regardless of the preferred method, the procedure takes approximately 60 seconds to complete (longer if the output signal is unstable). -
Page 28: 3.10.2 Digital Procedure
The procedure described here is by no means a proper calibration procedure; it can only be used to get a quick impression of the calibration status of an instrument. Performing a reliable calibration procedure requires thorough knowledge of the many parameters involved. Bronkhorst has skilled and experienced staff available that can take care of calibration matters; contact your Bronkhorst representative for information. -
Page 29: Digital Parameters
