It contains general product information, installation and operating instructions and troubleshooting tips. 1.2. Intended use The MASS-STREAM D-6400 is designed to accurately measure and/or control gas flow rates in a fluid system using the media and operating conditions (e.g. temperature, pressure) that were specified at ordering time.
Inlet connection Outlet connection The MASS-STREAM D-6400 instruments are measurement devices for thermal mass flow and control of gases. They are equipped with a digital electronic multi-bus pc-board and consist of a micro-controller with peripheral circuitry for measuring, controlling and communication. The flow signal is measured directly in the gas flow, digitized and processed by means of the internal software (firmware).
The MASS-STREAM D-6400 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 included in the scope of delivery or can be provided on request.

Use the equipment in an environment with a stable ambient pressure and temperature. The instruments’ preferred mounting position is horizontally (upright). Especially when installing bigger mass flow controllers (D-6471 and bigger) in different ways you should get in contact with your distributor or Bronkhorst Instruments GmbH beforehand.
2.6. Fluid connection Install the MASS-STREAM D-6400 meter/controller in the line, in accordance with the direction of the FLOW arrow on the body of the instrument. All devices have Withworth pipe threads – type RP – according to ISO228-1 (cylindrical G-threads in inches according to BSPP).

® ® Digital Bronkhorst instruments can be operated via RS232 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.

3.7. 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. at stable process conditions), the zero point will remain stable. However, over time several factors can induce a slight deviation of the measured value from the zero point, causing the instrument to detect a flow when in reality ther is none.
