Tantalum Excellence: Tantalum acts similarly to glass in terms of chemical resistance but possesses the strength and ductility of metal, making it immune to almost all acidic attacks.
Precision Batching: With ±0.10% mass flow accuracy, the TA-Series ensures that high-value corrosive chemicals are dosed with absolute consistency, reducing waste and improving batch quality.
Smart Meter Verification (SMV): Check the health of your tantalum tubes in real-time without stopping the flow or removing the meter from the line. Ensure integrity in your most hazardous loops.
Advanced Logging: The on-board historian and logging capabilities of the 5700 transmitter allow for deep-dive diagnostics and audit trails, essential for chemical safety compliance.
Multivariable Outputs: Get mass flow, volume flow, density, and temperature simultaneously from one tantalum-armored device.
Designed for modern industrial ecosystems, the TA-Series supports a wide range of communication protocols:
Digital: HART, Modbus RS485, EtherNet/IP, PROFINET, FOUNDATION Fieldbus.
Analog: Multiple mA outputs and Frequency/Pulse outputs.
The Challenge: A chemical facility was recovering 98% concentrated sulfuric acid at high temperatures. Previous meters made of Hastelloy-C failed within months due to severe corrosion, leading to frequent leaks and safety hazards.
The Hanyu Solution: The plant upgraded to the Micro Motion TA-Series with pure tantalum wetted parts from
The Result: The tantalum tubes showed zero corrosion after two years of continuous operation.
The Impact: The plant eliminated unplanned maintenance shutdowns and significantly increased worker safety. The precision density measurement allowed them to optimize the acid concentration process in real-time, saving thousands in raw material costs.
Q: When should I choose the TA-Series over the T-Series (Titanium)?
A: While titanium is excellent for chlorides and salt water, Pure Tantalum is required for strong, hot mineral acids (like H2SO4 or HCl) that would rapidly dissolve titanium or stainless steel.
Q: Why is it only offered with the 5700 transmitter?
A: The 5700 9-wire transmitter is Micro Motion’s most advanced electronics platform. It is required to provide the high-speed processing and advanced diagnostics (like SMV) necessary to manage high-stakes, corrosive applications.
Q: Can the TA-Series handle gas measurement?
A: The TA-Series is optimized for liquid flow and density. For gas applications involving corrosive media, please contact Hanyu Zhilian for a specialized application review.
Q4: How does Hanyu Zhilian handle international shipping for such specialized equipment?
A: We provide secure, specialized packaging and handle all export documentation. Every TA-Series unit is factory-certified for peace of mind. All project details are kept confidential per our Privacy Policy.
