The Micro Motion TA200T (DN50) is a 2-inch Coriolis flow meter engineered for applications where even the highest-grade nickel alloys fail. By utilizing Tantalum wetted components—a material renowned for its total immunity to almost all acids—the TA200T provides a robust and repeatable measurement solution for high-volume corrosive service.

The Tantalum Advantage: Tantalum is globally recognized for its incredible resistance to aggressive chemicals at elevated temperatures. Choosing the TA200T eliminates the frequent sensor replacements and catastrophic leak risks associated with using lesser materials in acid service.
High-Volume Precision: With a liquid mass flow accuracy of ±0.10%, the TA200T allows for precise inventory control and bulk transfer of high-value, high-risk chemicals, minimizing product loss.
Powered by the 5700 Transmitter: The TA200T is optimized for use with the Emerson 5700 9-wire transmitter, offering the industry's best signal processing, extensive diagnostic logging, and a built-in on-board historian.
Smart Meter Verification (SMV): In high-volume corrosive lines, manual inspection is dangerous. SMV enables you to verify the health of the tantalum tubes and the electronic calibration in-situ, ensuring measurement integrity without process exposure.
Multivariable Efficiency: One device provides mass flow, volume flow, density, and temperature. This reduces the number of penetrations required in your 2-inch piping, further enhancing system safety.
Advanced Process Tracking: Utilize the integrated historian to monitor for process upsets or potential sensor fouling, enabling proactive maintenance.
Industrial Communication: Seamlessly connects to modern DCS and PLC systems via HART, Modbus, and EtherNet/IP through the 5700 platform.
Certified Safety: Fully compliant with global hazardous area standards (ATEX, IECEx, CSA), ensuring safe deployment in refineries and specialized chemical plants.
The Challenge: A large-scale chemical site was transferring 98% Sulfuric Acid through 2-inch lines. Standard 316L and even Alloy C22 meters were experiencing pitting and stress corrosion, leading to monthly maintenance shutdowns and safety hazards.
The Hanyu Solution: The site upgraded to the Micro Motion TA200T from
The Result: The Tantalum tubes remained completely unaffected by the acid. The meter provided a rock-stable ±0.10% accuracy for over 3 years without requiring removal from the line.
The Impact: Shutdowns were reduced to zero, maintenance costs were slashed by 95%, and the plant significantly improved its environmental compliance by preventing potential acid spills.
Q: Is Tantalum worth the investment compared to Hastelloy C22?
A: For "clean" corrosives like hot HCl or $H_2SO_4$, Tantalum (TA200T) often lasts 10x longer than C22. If your process costs are high due to downtime or sensor failure, the TA200T offers the lowest total cost of ownership.
Q: Why does it only work with the 5700 transmitter?
A: The 5700’s advanced 9-wire digital technology is required to handle the specific signal profile of the Tantalum sensors, ensuring you get the full ±0.10% accuracy across all flow rates.
Q: Can it be used for density measurement?
A: Absolutely. It provides highly accurate liquid density measurement (±0.001 $g/cm^3$), which is essential for concentration monitoring and quality control in chemical blending.
Q4: How does Hanyu Zhilian ensure the quality of these premium sensors?
A: We provide 100% original factory-new units with full Material Traceability Reports (MTRs) and original calibration data. Due to the high value of Tantalum, all TA200T orders include specialized secure shipping and handling. All project details are strictly confidential.
