FAQ: Slurry Flow Measurement – Challenges and Solutions
1. Why is slurry flow measurement so difficult?
Slurry contains solid particles that cause abrasion, noise, and coating. Ordinary flow meters wear out quickly, lose accuracy, or produce unstable signals. Special materials and signal processing are required.
2. What is the biggest problem in slurry applications?
Abrasion. Hard particles (quartz, iron ore, etc.) wear down the liner and electrodes. At velocities above 3 m/s, a standard rubber liner may fail in 3 months. R&B uses abrasion‑resistant liners and hardened electrodes to extend service life.
3. How does coating affect measurement?
Sticky particles build up on electrodes, causing signal drift or complete failure. R&B flow meters offer self‑diagnosing features and options for easy electrode cleaning without disassembly.
4. Can slurry cause unstable flow readings?
Yes. Particle impacts generate random noise spikes. Ordinary meters output fluctuating signals, confusing control systems. R&B meters use advanced digital filtering and adaptive algorithms to deliver stable, reliable readings.
5. What about non‑Newtonian slurry behavior?
Slurry viscosity changes with flow velocity. Some flow meters can have up to 15% error. R&B electromagnetic flow meters are largely insensitive to viscosity changes, as long as the fluid is conductive.
6. Can R&B flow meters handle high pressure (42 MPa)?
Absolutely. R&B offers high‑pressure models up to 42 MPa, suitable for deep‑well injection, hydro transport, and other extreme processes. Sealing and liner materials are specially engineered for such conditions.
7. How do R&B flow meters compare with global brands (Endress+Hauser, Krohne, Siemens)?
R&B delivers the same accuracy and durability at 20‑40% lower cost. We also offer shorter lead times, flexible customization, and dedicated technical support. Many customers have successfully replaced premium brands with R&B.
8. What about maintenance and total cost of ownership?
Slurry meters need frequent maintenance. R&B reduces that by using wear‑resistant materials and robust construction. Lower purchase price + longer lifetime + less downtime = significantly lower TCO.
9. How do I select the right liner and electrode?
Selection depends on particle size, velocity, temperature, pH, and abrasiveness. R&B provides free engineering consultation. Contact us with your process data – we will recommend the optimal materials for your slurry.
