Overview

Spirit IT Flow-Xpert is based on the Spirit IT Flow-X flow computer calculation library that is used in numerous installations and is verified by many test laboratories and oil and gas companies. It provides all the typical fluid and hydrocarbon property calculations used for custody measurement (AGA, API, ASTM, GERG, GPA, ISO etc.).

The free iOS and Android apps can be used to verify single calculations. The Excel add-in allows you to build your own tool to verify and audit flow computers, volume correctors, EFM's and RTUS. The DLL interface allows for the integration of proven oil and gas calculations in any automation system.

Spirit IT Flow-Xpert supports both the metric and US Customary versions of the AGA and API implementations.
