From the developer:
Realflo is an application that enables custody transfer gas flow measurement of up to ten flow runs in our SCADAPack Smart RTUs. The application provides EFM functionality independent of, yet concurrent with, the Smart RTU’s Ladder Logic/IEC6-1131-3 and C/C++ user programmability.
You may want to check out more software, such as Riptide, 3D Studio VIZ R3 or P-CAD 2004 Viewer, which might be related to RealFLO.
