The Micro Motion TA100T (DN25) is a 1-inch Coriolis flow meter engineered for the "impossible" chemicals. By utilizing Tantalum—the most chemically resistant metal used in flow instrumentation—the TA100T provides a robust and reliable measurement solution where special alloys like Hastelloy would fail within weeks.

The Tantalum Standard: Tantalum's unique properties provide immunity to almost all chemical attacks, including hydrochloric, sulfuric, and nitric acids. The TA100T eliminates the frequent downtime and safety risks caused by sensor corrosion.
High-Accuracy Control: With liquid mass flow accuracy of ±0.10%, the TA100T allows for precise control of reactive ingredients, optimizing chemical yields and reducing raw material waste.
Smart Meter Verification (SMV): In corrosive service, knowing your sensor is healthy is vital. SMV allows you to verify the tantalum tubes and electronic calibration in-situ without exposing personnel to hazardous process fluids.
Exclusive 5700 Integration: The TA100T works solely with the Emerson 5700 transmitter, providing the industry's best multivariable processing, on-board historian, and advanced diagnostics for real-time process tracking.
Drainable Compact Design: The F-Series geometry allows for easy self-draining, which is critical in corrosive lines to prevent acid stagnation and simplify flushing during maintenance.
Advanced Process Monitoring: Capture and store process data directly in the transmitter to troubleshoot upsets and improve long-term process stability.
Digital Communication: Fully compatible with HART, Modbus, and EtherNet/IP through the 5700 transmitter platform.
Global Safety Approvals: Fully certified for use in hazardous areas (Class 1 Div 1, ATEX Zone 0/1), providing peace of mind for high-risk chemical processing plants.
The Challenge: A pharmaceutical facility was using a 1-inch line to batch hot concentrated HCl. Their previous stainless steel meters were suffering from pitting corrosion, leading to yearly replacements and calibration drift.
The Hanyu Solution: The facility upgraded to the Micro Motion TA100T from
The Result: The Tantalum wetted parts showed zero corrosion after 3 years. The meter maintained a stable ±0.10% accuracy, eliminating batch variability.
The Impact: Total cost of ownership was reduced by 70%, and the facility successfully passed its safety audits by demonstrating the integrity of its acid dosing system via SMV.
Q: Why use the TA100T instead of a Nickel Alloy C22 meter?A: While C22 is versatile, it can still corrode in hot, concentrated hydrochloric or nitric acids. Tantalum (TA100T) is essentially "immortal" in these fluids, providing much higher reliability and safety in extreme acids.
Q: Does the 40 bar pressure limit apply to all temperatures?A: Pressure ratings may change based on process temperature. Please consult the official Micro Motion Tantalum pressure/temperature charts or contact Hanyu Zhilian for specific engineering support.
Q: Can I use this with any Micro Motion transmitter?A: No. To achieve the specified accuracy and diagnostics, the TA100T is only compatible with the 5700 9-wire transmitter.
Q4: How does Hanyu Zhilian support international shipping for Tantalum sensors?A: We offer 100% original factory units with full Material Traceability Reports (MTRs) and calibration certificates. Given the high value of Tantalum, we use specialized secure packaging and tracked international shipping. All client data is confidential per our Privacy Policy.
