Overview

MCG 3905

For terminal operators, bulk storage managers, inventory accountants, automation engineers, and compliance teams who need accurate, real-time visibility into tank inventories across complex facilities, the MCG 3905 WINGauge Inventory Management System delivers a scalable, Windows-based platform for enterprise-class tank monitoring and reporting.
WINGauge supports up to 1,000 tanks across 32 field loops, integrating seamlessly with L&J radar, servo, float & tape, temperature, and alarm devices—as well as selected third-party gauges. Unlike basic inventory software, WINGauge combines real-time monitoring, historical trending, alarm management, and SQL-based data storage in a single system designed specifically for custody transfer, compliance reporting, and operational control.
With customizable operator displays, dynamic report generation, multi-protocol communications, and optional redundant server architectures, WINGauge provides a future-ready foundation for terminals, refineries, chemical plants, and bulk liquid storage facilities that require accuracy, auditability, and long-term scalability.
