    Software & electronics

    The electronic and software backbone of every metering installation - from AGA-compliant flow computers to secure SCADA integration and remote diagnostics.

    MIDNMiIEC 62443
    Overview

    Flow computers, telemetry and SCADA integration to AGA, ISO and IEC.

    GGS delivers the full electronic stack: flow computers performing AGA3, AGA7, AGA8 and ISO 6976 calculations; secure communication gateways with Modbus, HART, OPC UA and IEC 60870; and integration into operator SCADA platforms with full data validation and audit trails.

    All systems are designed to IEC 62443 cyber-security guidance and integrated with our calibration and control system packages so a single software environment owns the metrological loop end-to-end.
