Review ROSEMOUNT Magnetic Flowtube

The Rosemount 8705THA080C1W0E5 and 8705TSA020S3W3N0 magnetic flow tubes are precision-engineered, high-performance flow measurement solutions designed for demanding industrial applications where reliability, accuracy, and durability are paramount. These flow tubes are integral components of Rosemount s 8700 series of electromagnetic (magmetal) flow meters, which are widely recognized for their ability to measure the flow of conductive liquids such as water, wastewater, chemicals, slurries, and food-grade liquids with exceptional consistency across a broad range of process conditions. The 8705THA080C1W0E5 features a **thin-walled, high-alloy stainless steel (316L) construction** with a **8-inch nominal diameter (DN200)**, making it ideal for medium to large flow applications in industries such as municipal water treatment, power generation, and chemical processing. Its **thin-walled design** minimizes pressure drop while maintaining structural integrity, ensuring efficient operation even at high velocities. The **C1W0E5 designation** indicates a specific material and coating combination likely a **316L stainless steel tube with a protective epoxy lining (E5)** which enhances corrosion resistance and extends the tube s lifespan in aggressive or abrasive environments. The **THA variant** is optimized for applications requiring **high accuracy and repeatability**, often paired with Rosemount s advanced electronics for superior signal processing and compensation for temperature, density, and conductivity variations.

On the other hand, the **8705TSA020S3W3N0** represents a **thin-walled, high-performance flow tube with a 2-inch nominal diameter (DN50)**, tailored for smaller-scale applications such as laboratory systems, pharmaceutical processing, or low-flow industrial circuits. This model incorporates **S3W3N0 specifications**, which denote a **thin-walled, 316L stainless steel tube with a specialized lining (W3, likely a fluoropolymer or similar high-performance coating)** and **N0, indicating a non-magnetic, non-conductive interior** to prevent signal interference and ensure clean, accurate measurements. The **TSA designation** suggests it is designed for **turbulent flow applications**, where the tube s smooth interior and optimized geometry help maintain laminar flow characteristics even at varying velocities, reducing turbulence-induced errors. Both flow tubes are engineered with **Rosemount s proprietary electrode and excitation coil technology**, which ensures stable, interference-free signals and long-term operational reliability. The **thin-walled construction** of these tubes not only reduces material costs but also allows for faster response times and lower maintenance requirements, as there are fewer crevices for debris or biofilm accumulation. Additionally, the **modular design** of the 8700 series enables easy installation and replacement, with compatibility across a wide range of Rosemount transmitters and accessories, including those featuring **HART, Foundation Fieldbus, or Profibus communication protocols**, making them versatile for integration into modern SCADA and automation systems.

Whether deployed in a **high-volume municipal water distribution system** or a **precision chemical mixing application**, these Rosemount flow tubes deliver unmatched performance. Their **corrosion-resistant materials, precise manufacturing tolerances, and advanced signal processing capabilities** ensure consistent, drift-free measurements even under harsh conditions, such as high temperatures, fluctuating pressures, or exposure to corrosive chemicals. The **thin-walled design** further enhances their suitability for applications where minimizing pressure loss is critical, while the **durable construction** guarantees longevity in demanding environments. By leveraging Rosemount s decades of expertise in electromagnetic flow measurement, these tubes provide operators with the confidence of **high-accuracy, low-maintenance flow monitoring**, ultimately contributing to improved process efficiency, reduced downtime, and enhanced safety across a wide spectrum of industrial and commercial applications.

#### **Cons**

1. **High Initial Cost** Compared to some generic or lower-end magnetic flow tubes, the Rosemount 8705 series can be expensive, which may be a barrier for smaller businesses or budget-conscious buyers.

2. **Limited to Clean Liquids** This model is not designed for slurries, gases, or highly abrasive fluids, restricting its use to specific applications.

3. **Potential for Signal Interference** In environments with strong electromagnetic fields, the performance of the magnetic flow tube may be affected, requiring shielding or additional precautions.

4. **Specialized Installation Requirements** Proper installation, including correct pipe sizing and alignment, is critical to ensure accurate readings. Improper installation can lead to inaccuracies or damage.

5. **Limited Availability of Spare Parts** While Rosemount is a reputable brand, finding replacement parts or compatible accessories may be more challenging than with more widely available alternatives.

6. **Calibration Needs** Like all flow meters, the Rosemount 8705 requires periodic calibration to maintain accuracy, which may involve additional labor or service costs.

7. **Not Ideal for High-Pressure or Extreme Temperature Applications** While it handles a range of conditions, it may not be suitable for very high-pressure or extreme temperature environments without additional modifications.

### **Conclusion**

The Rosemount 8705TSA020S3W3N0 magnetic flow tube is a high-quality, reliable choice for applications requiring precise flow measurement of clean liquids. Its durability, accuracy, and compatibility with Rosemount systems make it a strong option for industries where consistency and performance are critical. However, its higher cost, limited application range, and specific installation requirements may not make it the best fit for all users, particularly those with budget constraints or non-clean liquid applications.

### **Recommendation**

If your application involves clean liquids, requires high accuracy, and fits within a budget that can accommodate the initial investment, the Rosemount 8705TSA020S3W3N0 is an excellent long-term solution. For smaller operations, budget-sensitive projects, or applications involving slurries or gases, consider alternative magnetic flow tubes from other manufacturers that may offer comparable performance at a lower cost. Always ensure that the installation meets Rosemount s specifications to maximize accuracy and lifespan. If possible, consult with a flow measurement specialist to confirm compatibility with your specific process conditions.
