SOLIDS, ABRASION & ENTRAINED GAS

Industrial Slurry Flow Measurement

Slurry flow selection must treat the carrier liquid, solids, particle behavior, abrasion and entrained gas as one application. A technology suitable for clean liquid may not remain suitable in the slurry.

DIRECT ANSWER

What is the practical starting point?

Electromagnetic flow is a strong starting point for conductive slurries because it can provide an unobstructed bore, while Coriolis may be considered when direct mass flow or density information is important and the pipe size and process are suitable. Liner, electrodes, velocity, gas content and installation determine the practical result.

APPLICATION BOUNDARIES

When to use—and when to stop and review

When to consider this approach

  • Conductive mineral, wastewater or process slurries with characterized solids
  • Full-pipe applications with defined minimum and maximum velocity
  • Projects that can review liner, electrode, grounding and wear conditions

When not to assume suitability

  • Do not select from solids percentage alone; particle size, hardness and behavior matter.
  • Do not ignore entrained air or settling during low flow.
  • Do not assume a standard liner or electrode material is compatible with abrasion and chemistry.

TECHNOLOGY COMPARISON

Compare the decision factors

Starting pointPotential advantageApplication boundary
Electromagnetic flowmeterFull-bore volume flow for conductive liquids and many solids-bearing streamsConductivity, entrained gas, liner wear, electrode coating and grounding require review
Coriolis flowmeterDirect mass flow and density from one measuring principleTube geometry, pressure loss, vibration, erosion and size economics can limit suitability
Ultrasonic flowmeterInline or clamp-on options exist for selected servicesBubbles, solids distribution, pipe condition and acoustic path can reduce measurement margin

EXAMPLE APPLICATION

How to frame the requirement

For a mineral slurry line, provide a sample or composition record plus the solids range, largest expected particle, carrier liquid, gas entrainment, flow profile and pipe orientation before choosing the meter lining and installation.

FAQ

Questions engineers ask first

Last reviewed:

Is a magmeter suitable for every slurry?

No. The carrier must meet the selected meter’s conductivity requirement, and abrasion, coating, entrained gas, velocity, liner and electrodes must be evaluated.

Why is minimum velocity important?

Low velocity can allow solids to settle and change the phase distribution, while excessive velocity can increase wear. The acceptable range is application and model specific.
