MCG 2000MAX

Terminal operators, plant engineers, maintenance technicians, and EPC project teams require accurate and reliable tank level data that integrates easily with control and inventory systems.

The MCG 2000MAX Level Transmitter provides continuous digital tank level measurement using absolute magnetic encoding technology, delivering precise and reliable readings in demanding industrial environments.

Unlike traditional float or mechanical transmitters that may lose calibration or drift after power interruptions, the MCG 2000MAX retains the correct tank level even after outages or system resets. Its patented Absolute Magnetic Encoding technology ensures the system always remembers the correct level position without requiring recalibration.

The transmitter features a 2-wire loop-powered design, infrared calibration capability, guided configuration setup, and multi-protocol output options including L&J Tankway and HART.

With ATEX and IECEx certifications, ultra-low power consumption, and measurement resolution down to 1/64 inch (0.4 mm), the MCG 2000MAX provides a safe, maintenance-free, and globally compliant solution for modern tank gauging and automation systems.

MCG 2000MAX Level Transmitter

Details

The MCG 2000MAX is designed to simplify tank level monitoring and automation across industries where reliability, compliance, and compatibility with existing infrastructure are essential.

The transmitter converts the movement of a mechanical tank gauge into precise electronic measurement signals using absolute magnetic encoding. This approach maintains measurement accuracy even in environments with vibration, power interruptions, or harsh weather conditions.

Built for petroleum terminals, chemical plants, water treatment facilities, and regulated manufacturing environments, the transmitter supports multi-protocol connectivity and field-upgradeable Smart Flash firmware.

The result is a transmitter platform capable of integrating with both legacy mechanical gauges and modern digital monitoring systems, allowing facilities to modernize measurement infrastructure without replacing existing equipment.

Applications

Custody Transfer and Inventory Management: Digitizes float gauge outputs to provide precise measurement data that supports reconciliation, auditing, and custody transfer accuracy.
Process Data Transmission: Transmits process measurements including level, temperature (spot or average), pressure, and alarms, consolidating field instrumentation data.
Retrofits and System Upgrades: Converts legacy mechanical gauge boards into electronic measurement systems without requiring tank downtime or major modifications.
Petroleum and Chemical Storage: Sealed electronics and hazardous area certifications ensure reliable performance in corrosive or hazardous environments.
Pharmaceutical and Food Processing: Provides accurate non-invasive measurement that helps reduce product loss and maintain strict regulatory compliance.
Water and Wastewater Facilities: Converts basic float gauge readings into reliable electronic signals suitable for SCADA integration and automated monitoring.

What makes the MCG 2000MAX different from other level transmitters?

−

The 2000MAX uses Absolute Magnetic Encoding — meaning it never loses level data during power interruptions and does not require recalibration after resets.

How does Absolute Magnetic Encoding prevent loss of level data?

Unlike older optical or incremental encoders that lose their position after a power interruption, Absolute Magnetic Encoding uses a series of permanent magnets to uniquely identify the exact position of the float at all times. When power is restored, the transmitter instantly reads the absolute position without needing to search or re-reference, guaranteeing true, continuous measurement and eliminating the need for recalibration.

Can the transmitter be retrofitted to existing float or tape gauges?

Yes. It directly couples to Varec 2500, Shand & Jurs 92021, and other standard mechanical gauges — ideal for upgrading without downtime.

Is it suitable for hazardous industrial environments?

Absolutely. It’s certified to UL, ATEX, IECEx, and CE standards for use in explosive or corrosive areas.

How is calibration performed?

Calibration and setup are done via infrared handheld and LCD interface — no need to open enclosures or access the tank top.

What happens if power is lost?

The MCG 2000MAX’s Absolute Magnetic Encoding ensures the level position is retained — it automatically restores the correct value on power-up.

What communication protocols are supported?

It supports 4–20 mA analog, L&J Tankway, and HART (with others available), allowing flexible integration into any control system.

How does Smart Flash technology support system upgrades?

It allows firmware updates and diagnostics without batteries or EEPROMs — reducing maintenance costs and extending service life.
