For terminal operators, custody transfer officers, automation engineers, and EPC project specifiers who require accurate tank inventory reporting and compliance with international standards, the MCG 2350 Average Temperature Converter (ATC) delivers a proven solution. This advanced, microprocessor-based device calculates the true average product temperature by receiving inputs from multiple RTD sensors placed along the tank’s height. Unlike single-point temperature measurement that is prone to errors from thermal stratification, the MCG 2350 ensures accurate volume and mass calculations, reducing volumetric error, protecting revenue, and meeting global audit requirements.
Achieves high accuracy (±0.1 °C) and meets API, ISO, and OIML requirements for custody transfer, protecting revenue by ensuring correct billing.
Processes inputs from up to 14 RTD elements to provide a representative average product temperature, eliminating errors caused by thermal stratification in large tanks.
Designed to work seamlessly with L&J radar and servo gauges, providing a complete, custody-ready solution for accurate volume and mass data.
Provides both analog (4–20 mA) and digital outputs (Modbus, HART, Tankway) for flexible integration into SCADA, DCS, or tank farm management systems.
Supports temperature measurements from –200 °C to +250 °C (RTD dependent), suitable for everything from cryogenic fluids to hot asphalt.

We have tried to answer the most common questions we are asked here.
In large storage tanks, liquids often experience thermal stratification, meaning the temperature varies significantly from the top to the bottom. Relying on a single-point sensor can lead to volumetric errors of up to in inventory calculations, which is unacceptable for custody transfer. The MCG 2350‘s multi-point averaging eliminates this bias.
Yes. The MCG 2350 is specifically designed to meet or exceed the requirements set by key international standards bodies, including API, ISO, and OIML, ensuring your temperature data is audit-ready and globally compliant.
Direct integration allows the entire gauging system (level and temperature) to function as a unified custody-transfer solution. The MCG 2350 provides the necessary temperature correction data directly to the gauge or host system, simplifying the architecture and ensuring the final volume or mass calculation is based on the most accurate data possible.
