Key features

Specifically Designed for Zinc Ore Slurry -Ideal for measuring zinc ore slurry, hydrocyclone feed, concentrate, and tailings in mineral processing plants.

Ceramic Carbide Lining - Provides excellent abrasion resistance against hard zinc ore particles (250-1500 microns), extending service life up to 3 years or longer.

Tungsten Carbide Electrodes - Minimizes signal noise from abrasive particle impact, delivering stable readings in the most challenging high-noise slurry applications.

Advanced Filtering Technology -Separates signal from noise without losing responsiveness to flow changes, ensuring stable flow rate readings.

Split Type Design - Sensor and transmitter separate; install transmitter away from pipeline vibration for stable performance.

Cost-Effective for Large Pipes - Much lower cost than full-bore meters for DN350-DN2000 pipelines; cost independent of pipe size.

Hot-Tap Installation - No pipe cutting, no flow interruption; install under full working pressure without plant shutdown.

No Moving Parts -Maintenance-free, no clogging, no pressure loss, long-term reliability in harsh slurry conditions.

IP68 Submersible - Sensor can be fully submerged; suitable for flooded chambers and outdoor mining installations.

Smart Communication -4-20mA, Pulse, RS485 Modbus, HART, GPRS/4G for SCADA integration.

Product Q&A

Q:Tungsten Carbide Electrode Flow Meter

Zinc ore particles are highly abrasive (250-1500 microns). Ceramic carbide lining provides excellent abrasion resistance and extends service life up to 3 years or longer .

Q:Why use tungsten carbide electrodes?

Tungsten carbide electrodes minimize signal noise caused by abrasive particles hitting the electrodes, ensuring stable, reliable readings .

Q:What is the recommended installation orientation?

Vertical installation with flow upward is recommended for slurry to prevent particle settling and ensure accurate measurement .

Q:What pipe sizes does this meter support?

DN350 to DN2000. Larger sizes are available on request.

Q:Does it require cutting the pipe for installation?

No. It uses hot-tap installation -no pipe cutting, no flow interruption, no plant shutdown .
