The Tantalum Advantage: Tantalum creates a durable oxide layer that resists corrosion from hot concentrated acids (like HCl and $H_2SO_4$), preventing sensor failure and eliminating the risk of hazardous leaks.
Precision for High-Value Chemicals: With a liquid mass flow accuracy of ±0.10%, the TA025T allows for the exact dosing of expensive reagents, reducing chemical waste and improving batch quality.
Exclusively Paired with the 5700 Transmitter: This sensor is optimized for the Emerson 5700 9-wire transmitter, which provides superior signal processing, an on-board historian, and graphical diagnostics for complex data analysis.
Smart Meter Verification (SMV): In corrosive service, sensor integrity is critical. SMV allows you to verify that the tantalum tubes are healthy and the meter is in calibration—all without interrupting the flow or exposing technicians to hazardous fluids.
Robust Multivariable Data: Simultaneously measure mass flow, volume flow, density, and temperature, providing deep insights into your process from a single, high-durability device.
Advanced Diagnostics: The integrated historian and logging features track process upsets, helping you identify flow issues before they lead to costly downtime.
Digital Communication: Fully compatible with industry-standard protocols including HART, Modbus, and EtherNet/IP through the 5700 platform.
Hazardous Area Safety: Certified by CSA, IECEx, and ATEX, making it the safest choice for explosive or high-risk chemical processing zones.
The Challenge: A chemical manufacturer was replacing stainless steel meters every 6 months due to corrosion from hot concentrated hydrochloric acid. The leaks were a major safety risk and caused significant production loss.
The Hanyu Solution: The plant upgraded to the Micro Motion TA025T from
The Result: The Tantalum tubes showed zero signs of wear after 24 months of continuous service. The meter maintained a stable ±0.10% accuracy.
The Impact: Maintenance costs were eliminated, and the facility significantly improved its safety rating by removing a primary source of chemical leaks.
Q: When should I choose Tantalum (TA-Series) over Nickel Alloy C22?
A: If your fluid contains high concentrations of sulfuric, nitric, or hydrochloric acid at elevated temperatures, Tantalum is the only material that provides long-term survival. C22 is excellent for many corrosives, but Tantalum is the "final step" in chemical resistance.
Q: Why is the TA025T only offered with the 5700 transmitter?
A: The 5700 transmitter provides the high-fidelity 9-wire signal processing required to maintain the ultra-high ±0.10% accuracy with Tantalum tubes across all process conditions.
Q: Is it suitable for high-pressure applications?
A: The TA025T is rated up to 40 barg (580 psig). For higher pressure requirements, please consult with Hanyu Zhilian for specialized sensor options.
Q4: How does Hanyu Zhilian ensure the quality of Tantalum meters?
A: We provide 100% original factory units with full Material Traceability Reports (MTRs) and original calibration certificates. Due to the high value of Tantalum, we handle all shipping with specialized insurance and reinforced packaging. All project data is confidential.
