Dynamic Data Exchange (DDE)
RS232 communication can be used for operating the instrument using the Bronkhorst FlowDDE server application. Dynamic Data
Exchange (DDE) provides the user a basic level of interprocess communication between Windows applications. FlowDDE is a DDE
server application. Together with a client-application, either self-made or with a SCADA-program from third parties, it is possible to
create an easy way of data exchange between the flow controller and a Windows application. For example, a cell in Microsoft Excel
could be linked to the measured value of the LIQUI-FLOW
TM
mini and when the measured value changes, it will be updated
automatically in the Excel spreadsheet.

FlowDDE
The FlowDDE server also offers a lot of test facilities and user-adjustable settings for efficient communication with the connected
flow/pressure meter or controller. How to setup a DDE link with FlowDDE is described in the help-file of the FlowDDE application.
Programming examples are available for making applications in: Visual Basic, LabView and Microsoft Excel.
