Absolute Acid Resistance: Tantalum acts as a permanent barrier against corrosion from strong acids, chlorides, and oxidizing agents, eliminating the risk of tube failure and costly chemical leaks.
Fiscal-Grade Precision (±0.10%): Unlike plastic or lined meters that sacrifice accuracy for durability, the TA300T delivers ±0.10% mass flow accuracy, ensuring your most expensive chemicals are measured with scientific precision.
Paired with the 5700 Transmitter: The TA300T is offered exclusively with the Emerson 5700 transmitter. This combination provides the industry's most advanced signal processing, minimizing noise and maximizing stability in complex chemical flows.
Smart Meter Verification (SMV): In high-acid applications, pulling a meter for inspection is a hazardous and expensive task. SMV allows you to verify the structural integrity and calibration of the Tantalum tubes in-situ, ensuring safety and uptime without breaking the pipe.
Comprehensive Multivariable Data: Get real-time mass flow, density, temperature, and concentration (e.g., acid strength) from a single device, reducing the number of high-risk line penetrations.
On-Board Historian & Logging: Track process upsets and meter health over time with an integrated digital audit trail, essential for regulatory compliance and proactive maintenance.
9-Wire Connectivity: Optimized for the fastest response times and ultra-stable signal integrity between the Tantalum sensor and the transmitter.
Advanced Diagnostics: Detects entrained gas and process noise in real-time, allowing for accurate measurement even in aerated chemical streams.
Hazardous Area Ready: Fully certified by ATEX, IECEx, and CSA for use in the most volatile chemical processing zones.
The Challenge: A chemical manufacturer used PTFE-lined magnetic meters for 3-inch HCl lines. The liners frequently failed due to permeation, leading to dangerous leaks and frequent production stops.
The Hanyu Solution: The facility upgraded to the Micro Motion TA300T Tantalum meter paired with a 5700 transmitter from
The Result: The TA300T provided total resistance to HCl. The ±0.10% accuracy allowed the plant to optimize their dosing, reducing chemical waste significantly.
The Impact: Maintenance costs related to flow meter failure dropped to zero, and the meter has operated for over 3 years without a single sign of corrosion or drift.
Q: Why is the pressure rating lower (16 barg) compared to stainless steel meters?
A: Tantalum is a specialized material with unique mechanical properties. The 16 barg rating is optimized to provide the perfect balance between extreme chemical resistance and the sensitivity required for Coriolis measurement.
Q: Can the TA300T measure acid concentration?
A: Yes. By utilizing its high-accuracy density measurement, the TA300T can provide real-time concentration data for sulfuric, hydrochloric, and other acids directly to your control system.
Q: Is Tantalum suitable for all acids?
A: Tantalum is resistant to almost all acids except for Hydrofluoric (HF) and strong hot alkalis. For most industrial chemical services, it is the most durable material available.
