MCG 2000MAX

The MCG 2000MAX Float and Tape Transmitter provides accurate, reliable tank level data that integrates easily with control and inventory systems. Designed for terminal operators, plant engineers, maintenance technicians, and EPC project teams, it delivers continuous digital measurement with magnetic precision and high reliability.

Unlike traditional float or mechanical transmitters that may lose calibration or drift after power interruptions, the MCG 2000MAX uses patented Absolute Magnetic Encoding technology to retain the correct tank level even after outages or resets. No recalibration is required.

Its two-wire loop-powered design, infrared calibration capability, guided setup, and support for multiple communication protocols make installation, configuration, and integration straightforward for both new installations and retrofit projects.

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

Features

Absolute Encoding Reliability

Magnetic encoding ensures level data is retained after power loss, preventing drift, recalibration needs, or measurement reset errors.

High-Resolution Accuracy

Standard 1/32″ (0.8 mm) resolution supports precise inventory control, with optional 1/64″ resolution for custody-grade applications.

Extended Measurement Range

Up to 128 ft capability covers tall storage tanks, enabling accurate monitoring across petroleum, chemical, and industrial vessels.

Retrofit Compatibility

Direct coupling to Varec and S&J mechanical gauges reduces installation effort, enabling modernization without tank shutdowns.

Ultra-Low Power Design

Consumes less than 0.04 W, ideal for 2-wire loop-powered systems requiring efficient, low-maintenance long-term operation.

Hazardous-Area Compliance

UL, ATEX, and IECEx approvals support deployment in global classified areas, ensuring safe and compliant field operation.

Mechanical Gauge Couplings

MCG 2000 MAX interfaces with any float and tape gauge, including the Varec 2500, S&J 92021, and similar gauges, to deliver electronic level, temperature, and optional alarm data.

Applications

  • Inventory Management: Digitizes float-gauge movement into precise electronic data that supports audit-ready reconciliation and prevents costly measurement discrepancies.
  • Retrofit Upgrades: Replaces mechanical transmitters without tank entry, modernizing existing infrastructure while reducing installation time and engineering cost.
  • Petroleum & Chemicals: Operates reliably in corrosive or hazardous atmospheres due to sealed electronics and global safety certifications.
  • Water & Wastewater: Converts basic float readings into dependable signals for SCADA monitoring, preventing overflows and reducing manual inspections including communicating cover position.

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 ensure level data is never lost?

+

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 it be retrofitted onto existing float and 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 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 options 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 help?

+

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

Summary

The MCG 2000MAX Level Transmitter delivers reliable, continuous tank level measurement using magnetic absolute encoding that retains data through power loss without recalibration. With 1/32-inch standard accuracy, ultra-low 0.04 W power consumption, and hazardous-area approvals, the MCG 2000MAX provides Cognesense’s proven measurement performance for petroleum, chemical, and industrial storage applications.
