Flow Meters for Mining & Slurry Industry
Heavy-Duty, Rugged & Abrasion-Resistant Solutions for Harsh Slurry Applications
The mining industry handles some of the harshest fluids found in any industrial environment. Slurries containing sand, gravel, rocks, minerals, ore concentrates, tailings, and chemical residues place extraordinary demands on flow meters. These fluids are abrasive, dense, corrosive, and highly inconsistent — requiring specialized instruments built for long-term reliability.
As a leading manufacturer & supplier, Saitechflow Instruments & Control (SFIC) provides industry-grade flow meters engineered specifically for mining and slurry applications. Our meters are designed using abrasion-resistant liners, reinforced electrodes, heavy-duty bodies, and advanced electronics to ensure accurate measurement even in the toughest operating conditions.

2. Challenges in Mining & Slurry Flow Measurement
Mining fluids present extreme measurement challenges:
- High abrasiveness
Slurries can contain stones, coarse solids, silica, and metallic particles.
- Variable slurry consistency
Density and viscosity change continuously.
- Low and high conductivity ranges
Some slurries conduct electricity well; others do not.
- Erosive wear
Pipeline walls, valves, and meter liners face severe wear.
- Difficult installation environments
Remote locations, underground mining tunnels, rugged terrains.
- High solids content
Tailings can exceed 60% solids.
- Corrosive chemicals
Used in mineral processing (acids, cyanide, leaching chemicals).
- Large diameter pipelines
Slurry pipelines can be DN100 to DN2000+.
- Vibrations and pump surges
Centrifugal pumps create pulsating flow.
Flow meters must therefore be extremely durable, stable, and designed specifically for slurry.
Saitechflow’s slurry-grade flow meters are engineered for these conditions.
3. Recommended Flow Meter Types for Mining & Slurry
