Flow-Xpert Features

Flow-Xpert, flow calculation software for your PC contains a large library of most international liquid and gas calculations.  This includes AGA, API, ISO and many more standards. All the calculations have been carefully and thoroughly tested by our Software Test and Development team and are certified by a metrological institute.

Validated Calculation Standards

The implemented calculation standards are part of Spirit Flow Suite, which is also used in our Flow-X series of flow computers and in the Virtual Flow Computer (VFC) software modules of our eXLerate software platform. Flow calculations have been carefully and thoroughly tested by our software test and development team and are certified by the Dutch metrological institute NMi.

Example calculations included

For each calculation standard, multiple working and practical examples are included on the installation disk, and can be easily used and modified as required. The calculations are all well documented in a separate manual, and additional on-line help is available for the library functions into your spreadsheet.

Different Editions

Flow-Xpert is available in 3 Editions:

• Flow-Xpert Basic Edition, a standalone calculation package for basic calculations
• Flow-Xpert Excel Edition, an Excel add-in library for fully flexible calculations
• Flow-Xpert Enterprise Edition, for usage in Enterprise software and other software systems.
