flow meters

In process industries, accurately measuring aggressive, abrasive, high-temperature, or high-pressure fluids is a persistent challenge. Traditional flow meters , especially those with elastomer (e.g., rubber , polyurethane ) or PTFE liners , often struggle with liner wear , chemical attack , temperature limitations , and the nagging issue of leaching . Is there a solution that combines ultimate durability, unmatched chemical inertness, and long-term, stable accuracy? The answer is a definitive yes: the Ceramic Liner Electromagnetic Flow Meter .   Today, we're excited to delve into this innovative technology and share some exciting news: two DN200 RBEF Series Ceramic Liner Magnetic Flow Meters have completed final testing and packaging and are ready for shipment to a customer seeking a reliable solution for their harsh operating conditions.     The Limits of Traditional Liners & The Ceramic Breakthrough   Electromagnetic flow meters (EMFs) are widely valued for...

 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....
