flow meters

Dear Partners & Friends, As the Chinese New Year is approaching, we would like to inform you of our holiday arrangement: Our company will be closed from February 14 to February 22, 2026 for the Spring Festival holiday . We will resume work on February 23. During the holiday, our business and email response will be temporarily suspended. We will attend to your inquiries, orders and pending matters immediately after we return to work. We wish you and your family a happy, healthy and prosperous Chinese New Year! hashtag # RB hashtag # Flowmeter hashtag # ChineseNewYear #2026

 Measuring abrasive slurries and mineral slags? You’re not alone. While electromagnetic flowmeters (magmeters) excel with clean conductive fluids, real-world industrial slurries push them to the edge. As engineers, we face these recurring pain points: 🔹 Abrasive Wear : Quartz, ore, or slag particles act like microscopic sandpaper—scouring electrodes and liners, causing calibration drift and premature failure. 🔹 Corrosive Assault : Acidic tailings or alkaline slurries devour standard stainless steel electrodes and rubber liners. Material mismatch = leaks or signal loss. 🔹 Scaling & Fouling : Mineral deposits or sludge coat electrodes, creating insulating barriers that block voltage signals—especially in high-solid-content flows. 🔹 Conductivity Limits : Magmeters need ≥5 μS/cm. Slurries diluted with non-conductive solids (sand, coal) often dip below threshold, killing signal integrity. 🔹 Physics Complications :  • Slip velocity between solid/liquid phases skews volume read...

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...
