FlowNavigator Flow Configuration Software FSA120

FlowNavigator (FSA120) is a unique software tool that helps you get the most out of the EJX910A / EJX930A Multivariable Transmitter by supporting the configuration of the discharge coefficient, primary device bore, upstream internal pipe diameter, gas expansion factor, density, and viscosity data needed to perform full compensation and dynamic calculation of the mass flow. It also helps you get the most out of the digitalYEWFLO Vortex Flowmeter for FOUNDATION fieldbus protocol by supporting AR block configuration of the density data. This powerful configuration tool has dialog windows that walk you through the entire configuration process.

FlowNavigator (FSA120) includes following two programs:

  • EJXMVTool: for EJX Multivariable Transmitter
  • DYFMVTool: for digitalYEWFLO Vortex Flowmeter

About OpreX

It consists of categories and families under each category. This product belongs to the OpreX Field Instruments family that is aligned under the OpreX Measurement category.



Flow Configuration Wizard
There are varieties of flow calculation modes.

  • Auto Compensation Mode (EJXMVTool), Detail (Gas / Liquid) Compensation Mode (DYFMVTool)

    FlowNavigator employs a series of dialog windows that simplify the process of configuring primary devices (Orifice, Nozzle, Venturi, Multiport Averaging Pitot and Cone meters for EJXMVTool) and fluid physical properties. With this software tool, you can be assured of getting the settings right for mass flow measurement and dynamic compensation, and making the fullest use of device's capabilities. It has the physical properties database for 125 fluids, Natural gas, steam table (for EJXMVTool) and custom fluids.

  • Basic Mode (EJXMVTool), Simple (Gas / Liquid) Compensation Mode (DYFMVTool)

    In addition to auto compensation mode, flow operation and density compensation can be performed by manually specifying flow factors such as the reference temperature, reference static pressure, and Kfactor, using known configuration information.

  • Steam Compensation Mode (DYFMVTool)

    Flow operation and density compensation can be performed by the flow factors inside digitalYEWFLO Vortex Flowmeter.

Flow Parameter Management
FlowNavigator has a variety of functions that make maximum use of valuable data that you have obtained. For example, a set of flow configuration data can be saved for downloading to a device and is also available in the CSV format, which is useful for the analysis of flow characteristics.

Device Parameter Management
The general parameters of the device can be edited or stored by Online/Offline parameter menu window in "EJX Multivariable Transmitter" / "digitalYEWFLO vortex flow meter" DTM bundled in FieldMate and PRM.
