Magnetic Flow Meters in Pulp & Paper Industry

The pulp and paper industry involves complex operations that require precise measurement of air, specialty gases, and liquids. Key applications include chemical dosing, bleaching, coloring, and black liquor processing. These processes often involve harsh environments with aggressive and abrasive media, posing significant challenges for measurement equipment.

Advantages of Magnetic Flow Meters

Customizable Materials: Can be configured with a range of materials to meet specific process requirements.

Non-Clogging Design: No ports or impulse lines, ensuring uninterrupted operation.

Full Diameter Flow Path: No pressure drop across the meter, maintaining system efficiency.

Cost-Effective: Suitable for a wide range of sizes, from fractional to over 36 inches.

Low Maintenance: Designed for durability and long-term reliability.

Challenges in Pulp & Paper Applications

Noisy stock flows, aggressive chemicals, abrasive materials, and high process temperatures can impact measurement accuracy.

Most magnetic flowmeters operate at low coil drive frequencies, which can result in low signal-to-noise ratios due to impingement noise.
