How is the flow rate of magnetic slurry measured?
Release time:
2026-01-05
Challenge:
Because commonly used electromagnetic flowmeters or Doppler ultrasonic flowmeters cannot overcome the challenges posed by flows containing magnetic slurries, the magnetic substances in magnetite cause significant and erratic deviations in the measurement results of magnetic flowmeters due to fluctuations in magnetic field strength, making compensation impossible.
Doppler ultrasonic flowmeters are difficult to maintain high accuracy and stability over the long term. When the slurry contains large particles, wear can lead to electrode failure and pipeline leaks, thereby affecting measurement accuracy. Such failures result in unscheduled repairs and replacements, increasing production costs.
Solution:
Using the Pulsar SONARtrac flowmeter, which employs non-contact, passive sonar technology, provides precise and stable readings with an exceptionally long instrument lifespan, thereby reducing costs. The flowmeter is unaffected by changes in physical properties such as solid content, magnetism, or temperature of the medium, and requires neither downtime nor recalibration. When pipelines are replaced or removed, the flowmeter can be easily detached and reinstalled on the new pipeline, or it can be conveniently clamped onto existing operational pipelines without any disruption to operations.
Suitable for pipelines made of various materials—including steel pipes, ceramic-lined pipes, rubber-lined pipes, PVC, HDPE, and steel-rubber composite pipes—more and more customers are using SONARtrac flow meters to replace ultrasonic and electromagnetic flow meters for monitoring applications such as feed lines to hydrocyclones, overflow lines from hydrocyclones, feed lines to mills, discharge lines from mills, concentrate lines, and tailings lines.
