Sigma Core is a scalable supervisory control and measurement software platform that combines real-time visualization, SCADA functions and data management with specialized fiscal, allocation and production measurement capabilities. It connects operators to flow computers, PLCs, analyzers and instrumentation through open interfaces, with interactive faceplates for measurements, diagnostics, alarm limits, calibration and proving, and historical trends. Advanced functions include batch reporting, meter proving, K-factor monitoring, gas chromatograph handling, condition-based monitoring and PVT calculations. Applications span oil and gas, hydrogen, terminals, utilities and process industries.
