Product Overview & Advantages

The Rosemount 2051TG Pressure Transmitter represents the pinnacle of Emerson's measurement technology specifically engineered for critical tank gauging applications. As a specialized variant within the renowned Rosemount 2051 series, the 2051TG is a high-accuracy, wet-wet differential pressure (DP) transmitter designed to provide exceptionally reliable level, interface, and density measurements for liquids stored in atmospheric or low-pressure tanks. Its core function utilizes the hydrostatic pressure principle – measuring the pressure difference between the bottom of the tank (high-pressure side) and the vapor space above the liquid (low-pressure side). This direct measurement, combined with sophisticated compensation and signal processing, delivers precise level data essential for inventory management, custody transfer, process control, and safety systems in industries like oil & gas (refining, terminals, pipelines), chemical processing, and power generation. 

Robust Reliability in Harsh Tank Farm Environments

Operating in exposed tank farms presents unique challenges: extreme temperatures, corrosive atmospheres, moisture, and potential physical impact. The Rosemount 2051TG is meticulously designed to thrive in these demanding conditions, ensuring continuous, trouble-free operation. Its sensor module features an all-welded, hermetically sealed construction with Hastelloy C-276 wetted parts, providing outstanding resistance to corrosion from a wide range of aggressive process fluids and atmospheric conditions. The robust, cast aluminum or optional stainless-steel housing offers superior protection against environmental ingress, achieving IP66, IP67, or IP68 ratings depending on configuration. The transmitter incorporates advanced diagnostics that monitor the health of the sensor, electronics, and communication, providing early warnings of potential issues before they impact measurement integrity or cause downtime. 

Unmatched Accuracy, Stability, and Performance

The defining advantage of the Rosemount 2051TG lies in its exceptional measurement accuracy and long-term stability, crucial for financial transactions (custody transfer) and efficient process optimization. Engineered with Emerson's industry-leading Silicon-on-Sapphire (SOS) sensor technology, the transmitter achieves remarkable performance, boasting ±0.025% accuracy when calibrated with Rosemount 1199 Remote Seals and ±0.04% with direct-mount seals. This sensor technology is inherently immune to hysteresis and non-repeatability errors, ensuring consistent readings over time. Furthermore, the 2051TG features sophisticated static pressure compensation, automatically correcting for the effects of varying vapor density and pressure above the liquid, a critical factor for accurate level readings, especially in large tanks experiencing significant temperature swings. Its wet-wet differential capability inherently eliminates errors associated with traditional dry-leg/wet-leg reference installations, simplifying system design and enhancing reliability. The result is minimized measurement uncertainty, maximized tank inventory accuracy, and increased confidence in operational decisions.

Advanced Features for Simplified Integration and Operational Excellence

Beyond core measurement, the Rosemount 2051TG offers a suite of advanced features designed to streamline installation, commissioning, operation, and maintenance, delivering significant operational value. Native integration with Emerson's PlantWeb™ digital ecosystem and AMS Device Manager software allows for powerful remote configuration, calibration management, and detailed diagnostics, minimizing the need for technicians to physically access often remote or hazardous tank locations. Features like "TankMapping" simplify configuration by allowing direct entry of tank strapping tables for precise volume calculation. The transmitter supports multiple industry-standard communication protocols (HART 5/7, FOUNDATION Fieldbus, Profibus PA) ensuring compatibility with diverse control systems. Its modular design facilitates easy replacement of electronics modules without breaking the process seal, reducing maintenance time and cost. Long-term stability minimizes calibration frequency, while features like the "Verify" diagnostics provide confidence in measurement validity. These capabilities collectively translate into reduced installation time, lower total cost of ownership through minimized maintenance and calibration needs, enhanced process visibility, improved decision-making, and maximized operational uptime for critical tank storage operations.
