Which Flowmeter is Best for Slurry? A Guide to Selecting the Right Technology

Discover the best flowmeter for slurry applications, including magmeters, and learn why RB Flowmeters' corrosion-resistant solutions excel in harsh environments. Explore key factors like temperature, pressure, and durability. 

 Understanding Slurry Flow Measurement Challenges 

Slurries—mixtures of liquids and abrasive solids—pose unique challenges for flow measurement. From mining and wastewater treatment to chemical processing, slurries demand equipment that can withstand corrosion, abrasion, and varying viscosities. Selecting the right flowmeter depends on factors like application scope, temperature, pressure, and material compatibility. 

 

Why Magmeters Excel in Slurry Applications 

Magnetic flowmeters (magmeters) are widely regarded as the top choice for slurry flow measurement due to their versatility and reliability. Here’s why: 

 1. Corrosion and Abrasion Resistance 

   Magmeters feature liners made of materials like ceramic, PTFE, or rubber, which resist corrosion from aggressive slurries. RB Flowmeters’ RFM-5000 Magmeter, for example, uses a ceramic-lined design ideal for mining slurries containing sharp particles. 

 2. No Moving Parts 

   With no obstructions in the flow path, magmeters minimize clogging and wear—a critical advantage for high-solid slurries. 

 3. Wide Temperature and Pressure Ranges 

   Magmeters operate efficiently in temperatures from -40°C to 180°C and handle pressures up to 25 bar, making them suitable for extreme industrial environments. 

 4. Accuracy in Conductive Fluids 

   Since slurries are typically conductive, magmeters provide ±0.5% accuracy even with fluctuating flow rates. 

 

Other Flowmeter Types: Pros and Cons 

While magmeters dominate slurry applications, other technologies have limitations: 

- Ultrasonic Flowmeters: Struggle with air bubbles or non-homogeneous slurries. 

- Coriolis Meters: High cost and sensitivity to vibration limit their use in rugged settings. 

- Differential Pressure (DP) Meters: Prone to clogging and require frequent maintenance. 

 

Key Factors for Choosing a Slurry Flowmeter 

1. Material Compatibility 

   Ensure wetted materials (liners, electrodes) resist chemical corrosion. RB Flowmeters offers customizable liners for acids, alkalis, and abrasive slurries. 

 

2. Temperature and Pressure Limits 

   Verify the flowmeter’s specs match your process conditions. For high-temperature slurries (e.g., geothermal sludge), RB’s HT Series handles up to 200°C. 

 

3. Installation Environment 

   In mining or wastewater plants, opt for magmeters with IP68-rated enclosures for dust and water resistance. 

 

4. Maintenance Requirements 

   Magmeters require minimal upkeep compared to mechanical meters, reducing downtime.
