flow meters

 If you work in mining , coal processing , pulp and paper , or mineral processing , you know the challenge isn't just measuring flow—it's surviving it. Fluids like coal slurry , mineral ore pulp , and paper stock are more than just liquids; they are abrasive, often corrosive, and packed with solids that act like liquid sandpaper on your equipment. Choosing the wrong flow meter here is a costly mistake, leading to rapid failure, inaccurate readings, and unplanned downtime that disrupts your entire process. After decades of global industrial application, one solution continues to stand out for its balance of durability, accuracy, and value: the properly specified, abrasion-resistant magnetic flow meter (magmeter). It's not the newest technology, but its targeted design and proven reliability make it the undisputed (best value-for-money champion) for these punishing duties. Why Does It Earn the Title? A Deep Dive into Three Core Advantages 1.  Engineered for Abuse: Where Long...

 Is your R&B Instrument Inc. RBFM Series ultrasonic flow meter acting up? Don't let downtime disrupt your process. This comprehensive guide walks you through common issues—from no power to inaccurate readings and signal problems —with clear, actionable steps and critical safety notes to get you back on track quickly and safely. Issue 1: No Display / Power Failure Troubleshooting Steps: 1.  Step 1 (Check Power Supply): Use a multimeter to measure the voltage supplied to the flow meter. 2.  Step 2 (Check Wiring): Verify that the wiring connections at the flow meter's power terminals are correct and secure. 3.  Step 3 (Inspect Power Module): If the power supply and wiring are correct but the unit still has no display, the internal power module may be faulty. Key Safety & Technical Notes: *   Power Specifications: Ensure the power source matches the device's rating (commonly DC24V or AC220V ±10%). Use a stable, reliable switch-mode power supply ...

  Chemical dosing represents one of the most challenging applications in flow measurement . Unlike bulk fluid transfer, dosing systems operate with three fundamental constraints: 1. Low Flow Rates : Often operating in milliliters per minute ranges 2. Demanding Accuracy Requirements : Typically ±1% or better for process control 3. Complex Fluid Characteristics : Corrosive, viscous, shear-sensitive, or non-conductive fluids The consequences of poor meter selection are substantial. Under-dosing can lead to process upsets, product quality issues, and non-compliance with environmental regulations. Over-dosing wastes expensive chemicals—a particularly critical concern with specialty additives costing hundreds of dollars per kilogram.  Technology Deep Dive: Comparing Core Solutions # Electromagnetic Flow Meters : The Industry Workhorse How They Work Electromagnetic (mag) meters operate on Faraday's Law of electromagnetic induction . As conductive fluids pass through a magnetic field...

  Intro: The Gritty Reality of Industrial Flow If you've ever tried to measure the flow of paper pulp , mining slurry , wastewater sludge , or any fluid packed with solids and fibers, you know it's a world apart from measuring clean water. These abrasive, sticky, and unpredictable mixtures are the ultimate test for any flow meter. Choosing the wrong technology can lead to rapid failure, inaccurate data, and costly downtime. Let's break down the top challenges and explore the most resilient measurement solutions that actually work in these tough conditions. The Top 10 Challenges in Slurry & Fibrous Fluid Measurement 1.  Severe Abrasion & Erosion: Hard particles like sand act like liquid sandpaper, grinding away at liners, electrodes, and measurement elements, leading to premature failure . 2.  Clogging & Coating: Fibrous materials can wrap around protruding parts, while sticky slurries coat internal surfaces, blocking flow paths and distorting measurements. 3....

  Struggling with erratic flow data from abrasive slurries or high-consistency pulp ? Unreliable measurement at points like refiner outlets disrupts automation, wastes raw materials, and compromises product quality.   Why Standard Flowmeters Fail with Slurries Paper pulp and similar media are destructive. Solids cause abrasive wear , while fibers create electrical "slurry noise" that drowns the true signal. For low-conductivity pulp (e.g., in insulating paper production ), standard meters often fail entirely.   Engineered for Stability: The RBHEF Series Our RBHEF Slurry Electromagnetic Flowmeter is built specifically for these challenges: - Multi-frequency excitation & advanced digital filtering combat noise for a rock-solid signal. - Handles extreme applications, including low-conductivity pulp (from 1 µS/cm). - Rugged construction with wear-resistant liners reduces downtime and extends service life.   Delivering Value Beyond Measurement We provide perfo...
