flow meters

This checklist provides a systematic approach to diagnosing and resolving common issues with magnetic flow meters , aligned with industrial maintenance best practices . A. Preliminary Verification *   Power Supply: Confirm power is within the meter's specified range (e.g., 24 VDC, 110/220 VAC). *  Grounding : Verify the grounding system is perfect. Poor grounding is a leading cause of noise and signal instability. *  Process Status: Ensure the pipe is full and the flow rate is above the meter's minimum cutoff value. B. Meter & Sensor Inspection *   Electrodes: Check for coating, corrosion, or short-circuiting. Clean if necessary. *   Liner: Inspect for damage, wear, or bulging that could expose electrodes. *   Field Coils: Measure coil resistance and compare to factory specification. Look for opens or shorts. *   Cable Integrity: Inspect sensor-to-transmitter cables for damage, moisture ingress, or loose connections. C. Pro...

Is your R&B Instrument Inc. RBFM Series ultrasonic flow meter acting up? Whether it's a blank display , erratic readings, or faulty output, downtime is costly. This step-by-step troubleshooting guide will help you diagnose and resolve the most common issues efficiently and safely.   Issue 1: No Display / Power Failure Step-by-Step Diagnosis: 1.  Step 1: Check Power Supply     *   Use a multimeter to measure the voltage at the flow meter's power input terminals. 2.  Step 2: Inspect Wiring Connections     *   Verify that the wiring to the flow meter's power terminals is correct, secure, and not damaged. 3.  Step 3: Investigate the Power Module     *   If power and wiring are confirmed correct but the display remains off, the internal power module may be faulty. ⚠️ Critical Notes & Safety: *   Voltage Specification: Ensure your power source matches the meter's rating (commonly DC24V or AC220...

 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 .
