Belsim Dashboards are a one-stop solution composed of tables and graphs. Created either in VALI or in MS Excel, they provide instant insight and highlight discrepancies at each tier organizational interest.
Belsim trending tool facilitates the exploitation of VALI results through VALI or MS Excel forms. Amongst many other benefits, the trends lead to proper evalutation of the reliability of instruments (i.e. check for discrepancy between measured and reconciled value) or equipment performance assessment, unit or plant level (i.e. for KPI/EnPI monitoring).
Trends can be generated from the model directly inside the software interface, offering a user-friendly tool for application management.
The user can navigate back and forth from the modeling part to the reporting part thanks to a complete integration between the different modules of the software.
- VALI provides reconciled data that can be directly accessed from the Distributed Control System (DCS) of the plant.
- DCS owner can create graphical displays that show raw versus reconciled data.
- DCS graphs can be configured to display in (nearly-)real time all relevant plant operation parameters delivered by VALI as soft (virtual) sensors.
- Soft sensors calculated by VALI range from heat duties on heat exchangers, to temperatures, pressures and flow rates on every point of the system, and to other custom calculated values (KPIs).
