MCG 3630

Terminal managers, control room operators, process engineers, and safety teams require a reliable way to view tank conditions in real time.

The MCG 3630 Touch Panel Tank Monitor provides a dedicated, industrial-grade touchscreen interface designed for continuous monitoring of tank parameters such as level, temperature, BS&W (Basic Sediment and Water), density, alarms, and movement trends.

Unlike generic HMI systems or PC-based monitoring tools, the MCG 3630 is purpose-built for tank farm operations. It offers configurable graphics, customizable summaries, alarm history tracking, and simplified setup for gauge addresses, communication protocols, and alarm setpoints.

The system supports L&J Tankway, Modbus, and wireless communication options, allowing straightforward integration with existing L&J gauges, transmitters, and host systems.

From refineries and chemical plants to bulk liquid terminals, the MCG 3630 provides centralized visibility, faster operational decision making, and scalable monitoring for up to 100 tanks as facilities expand.

Details

How It Works

The MCG 3630 continuously polls connected tank gauges using L&J Tankway or other configured communication protocols. It aggregates measurement data and displays the information across several operator-focused interface screens.

Real-Time View

Displays graphical tank levels with alarm indicators, movement arrows, and real-time readings for level, volume, and temperature.

Tank Configuration Page

Allows operators to configure tank parameters including communication settings, tank addresses, product names, and alarm setpoints such as level, temperature, and BS&W limits.

Alarm History Page

Provides a chronological record of alarms with timestamps and configurable data fields to support compliance tracking, audits, and operational reviews.

Tank Summary Page

Displays a text-based table showing key operational data such as level, temperature, BS&W, gross volume, net volume, available capacity, and rate of change.

These views simplify monitoring tasks and help ensure consistent decision making across multiple operators and shifts.

Applications

Tank Farm Monitoring: Provides real-time visibility of tank levels, alarms, and temperature trends, improving safety and inventory accuracy.
Refinery Operations: Supports custody transfer tanks, process tanks, and daily inventory management through centralized monitoring and alarm control.
Chemical and Petrochemical Plants: Ideal for hazardous liquid storage requiring accurate monitoring, traceability, and rapid response to alarm conditions.
Distribution Terminals: Consolidates data across multiple tank areas and loading racks to support efficient throughput and coordinated operations.
Remote Storage Facilities: Integrates with SCADA systems to provide remote monitoring capabilities while reducing onsite staffing requirements.
Water and Wastewater Treatment: Monitors tank levels and temperatures to support process control and prevent overflow events.

How does the MCG 3630 improve operational confidence in the control room?

−

The monitor provides immediate, centralized visibility of all critical tank parameters and alarm conditions. By simplifying access to this data through an intuitive touchscreen, operators can confidently monitor their assets, respond quickly to anomalies, and prevent overfill or product loss.

How many tanks can the MCG 3630 monitor?

The base system supports 10 tanks, expandable to 50 or 100 tanks through model-number options.

Can the display layout be customized for specific operations?

Yes. Operators can choose between graphical bar graphs, text-based summaries, and configurable alarm color indicators. Several fields—including product name, maximum fill, and display preferences—can be customized per tank.

What communication protocols are supported?

Standard options include L&J Tankway, Modbus RS-232, Modbus RS-485, Modbus Ethernet, and an optional wireless interface.

Does the system store alarm history?

Yes. The Alarm History page logs event type, tank number, alarm thresholds, and timestamps, supporting compliance and audit requirements.

Can it integrate with SCADA or inventory management systems?

Absolutely. The MCG 3630 provides host communication options so data can be forwarded to gauging systems, SCADA platforms, or enterprise inventory tools.

Is the MCG 3630 designed for harsh industrial environments?

Yes. It is built as a rugged, industrial-grade device with a dedicated enclosure designed for continuous 24/7 service in demanding control room or panel-mounted environments, offering much higher reliability than standard desktop or laptop-based monitoring solutions.

Can it work with larger inventory management platforms?

Yes. The MCG 3630 is designed for seamless integration and scalability. It communicates using industry-standard protocols like Modbus and L&J Tankway, allowing it to interface directly with L&J field devices and integrate into larger host systems, such as an Inventory Management System, as your facility expands.
