Review ABB 2011 905-026 Totalflow Rtd Probe Assembly

The **ABB 2011905-026 TotalFlow RTD Probe** is a high-performance, industrial-grade flow measurement device designed for precise and reliable monitoring of liquid flow rates in demanding applications. Part of ABB s advanced TotalFlow family of products, this probe integrates a **Resistance Temperature Detector (RTD)** with a **vortex shedding flow sensor**, combining temperature compensation and accurate flow measurement in a single, robust unit. Engineered for durability, the probe features a **stainless steel construction** with a **316L-grade housing**, ensuring exceptional resistance to corrosion, abrasion, and extreme environmental conditions making it ideal for use in chemical processing, water treatment, HVAC systems, and other industrial settings where reliability is critical. The RTD element, typically a **Pt100 sensor**, provides precise temperature readings, which are essential for correcting flow measurements to account for variations in fluid viscosity and density, thereby enhancing overall accuracy across a wide range of operating conditions.

The vortex shedding principle employed by the TotalFlow probe generates a stable and repeatable flow signal by detecting the alternating vortices formed downstream of a bluff body placed in the fluid stream. This method offers a **wide turndown ratio** (up to 10:1 or higher, depending on configuration) and is unaffected by changes in fluid density or compressibility, making it suitable for both clean and slightly contaminated liquids. The probe s **pneumatic or electronic output** (depending on the specific model variant) allows seamless integration with ABB s **TotalFlow transmitters or controllers**, enabling real-time monitoring, data logging, and process automation. Its **low-pressure drop design** minimizes energy consumption while maintaining high measurement accuracy, typically within ** 1% of reading** under optimal conditions.

For enhanced versatility, the 2011905-026 probe is available in multiple **pipe size ranges** (from small-diameter lines to larger industrial pipelines) and can be configured for **insertion or in-line mounting**, depending on the application requirements. The RTD component ensures that temperature fluctuations whether due to seasonal changes, process variations, or ambient conditions do not compromise flow measurement integrity, as the system automatically adjusts readings for viscosity and density corrections. Additionally, the probe s **self-diagnostic capabilities** and **long-term stability** reduce maintenance downtime, while its **IP68-rated sealing** ensures protection against dust, moisture, and harsh chemicals, even in the most challenging environments. Whether deployed in a municipal water treatment facility, a pharmaceutical manufacturing plant, or an oil and gas refinery, the ABB 2011905-026 TotalFlow RTD Probe delivers uncompromising performance, combining **high precision, reliability, and ease of installation** to meet the demands of modern industrial flow measurement systems.

### **Pros and Cons of buying a ABB 2011905-026 TotalFlow RTD Probe**

1. **High Accuracy and Reliability** The TotalFlow RTD probe is designed for precise flow measurement in industrial applications, ensuring consistent and accurate readings in various process conditions.

2. **Durability and Robust Construction** Built with high-quality materials, it is resistant to corrosion, abrasion, and extreme temperatures, making it suitable for harsh environments.

3. **Wide Compatibility** Works with ABB s TotalFlow flow meters, offering seamless integration with existing systems and supporting multiple media types (liquids, gases, and steam).

4. **Low Maintenance Requirements** The RTD (Resistance Temperature Detector) sensor is designed for long-term stability, reducing the need for frequent calibration or replacement.

5. **Industrial-Grade Performance** Suitable for applications in oil & gas, chemical processing, power generation, and water treatment, where reliability is critical.

6. **Easy Installation and Replacement** Designed for straightforward mounting and swapping, minimizing downtime during maintenance or upgrades.

7. **Long Lifespan** ABB components are known for durability, reducing long-term operational costs compared to cheaper alternatives.

1. **High Initial Cost** As a premium industrial sensor, the upfront price is significantly higher than basic or generic probes, which may be a barrier for smaller businesses or budget-conscious buyers.

2. **Limited Availability of Spare Parts** Due to its specialized nature, finding replacement parts or compatible alternatives may be challenging compared to more common sensors.

3. **Complex Calibration Needs** Requires proper setup and calibration to ensure optimal performance, which may demand specialized training or technical support.

4. **Potential Overkill for Small-Scale Use** If the application does not demand high-precision flow measurement, investing in this probe may be unnecessary, leading to wasted expenditure.

5. **Vendor Lock-In Risk** ABB s proprietary design means compatibility is primarily limited to their ecosystem, which could restrict flexibility if switching to another brand in the future.

6. **Warranty and Support Dependence** Performance and troubleshooting heavily rely on ABB s technical support, which may involve additional costs or delays if issues arise.

### **Recommendation**

- You require **high-precision flow measurement** in an industrial setting (e.g., oil & gas, chemical plants, power generation).

- Your system is **already integrated with ABB TotalFlow meters**, ensuring seamless compatibility.

- You can **justify the upfront cost** based on long-term reliability and reduced maintenance needs.

- Your application involves **harsh conditions** (high pressure, corrosive media, extreme temperatures) where cheaper alternatives would fail.

- Your budget is **limited**, and you can achieve similar results with a lower-cost, generic RTD probe.

- The application does **not require industrial-grade accuracy**, and a simpler sensor would suffice.

- You are **not committed to ABB s ecosystem** and may need flexibility to switch brands in the future.

- You lack **technical expertise** for proper installation, calibration, and troubleshooting.

- For cost-sensitive applications, evaluate **generic RTD probes** from brands like Omega or Honeywell, which offer comparable performance at a lower price.

- If compatibility with ABB s system is not critical, explore **third-party flow sensors** that meet your accuracy and durability requirements.

- Ensure you **verify warranty and support options** with ABB to mitigate risks associated with long-term reliability.
