Chongqing Chuanyi MFD1017A111A055ER1402141 Electromagnetic Flowmeter for Mineral Slurry
MFD1017A111A055ER1402141
The MFD Series Slurry Electromagnetic Flow Meter is an industrial-grade flow measurement solution specifically engineered to overcome severe two-phase liquid-solid measurement challenges in extreme abrasive and high-noise environments. Utilizing advanced multi-frequency excitation technology, digital signal processing (DSP), and customizable ultra-wear-resistant linings and electrodes, this rugged flowmeter effectively eliminates zero-point drift, continuous fluid noise, and signal spikes caused by high-density particle slurry friction. It easily measures difficult media with up to 70% solid concentration and 10% pulp consistency—such as mineral tailings, ore slurries, coal-water slurry, and paper pulp— delivering accurate, obstructionless, and low-maintenance flow monitoring for modern automated mining, chemical, and industrial processing plants.
The MFD Series Slurry Electromagnetic Flow Meter represents a purpose-built industrial flow measurement solution tailored specifically for severe-duty two-phase liquid-solid applications.
Standard electromagnetic flow meters often suffer from signal fluctuations, zero-point drift, and rapid lining wear when exposed to high-density slurries or abrasive solids. The MFD Series overcomes these challenges through integrated multi-frequency excitation, advanced digital signal processing (DSP), and customizable heavy-duty corrosion/abrasion-resistant materials.
Built upon Faraday’s Law of Electromagnetic Induction, the MFD Series operates without any moving parts or internal obstructions in the pipe channel, eliminating energy loss and preventing mechanical blockages caused by gravel, fibers, or thick sludge. With its ability to
handle solid concentrations up to 70% in mineral slurries and 10% in paper pulp, the meter provides exceptional accuracy (±0.5%) and zero-point stability even in turbulent or high-noise flow streams.
Designed for long-term operational integrity, the meter features an ultra-reliable double-sealed electrode construction (conical and line sealing) and rugged IP68 submersible sensor options. Whether integrated into modern digital plant networks via HART, Profibus, or RS485 communication protocols, or operated in harsh, hazardous outdoor explosion-proof zones, the MFD Series ensures seamless process automation, optimized resource recovery, and minimized
plant maintenance overhead.
Frequently Asked Questions
Q1: How does the MFD Series handle high noise caused by solid slurry friction?
The MFD Series utilizes multi-frequency excitation technology combined with intelligent adaptive digital filtering algorithms. This filters out electrostatic and friction noise caused by solid particles striking the electrodes, providing a smooth, accurate, and stable flow signal.
Q2: Which lining material should I choose for highly abrasive mining slurry?
For abrasive slurries containing coarse sand or mineral rocks, Polyurethane (PU) or Natural Rubber linings are recommended due to their high resilience and abrasion resistance. For high-temperature or chemical slurry environments, PFA or ETFE linings offer the best durability.
Q3: Can the MFD Slurry Flow Meter be installed underground or submerged in water?
Yes. When configured with an IP68 protection rating and a remote converter setup, the MFD flow sensor can be permanently submerged in water or buried underground up to a depth of 5 meters.
Q4: Is straight pipe length critical for installing the MFD slurry magmeter?
Thanks to advanced magnetic field distribution design, the straight pipe run requirements are significantly low. A minimum of 5D upstream and 2D downstream from the center of the meter is sufficient for precise measurement in standard piping layouts.
