Chongqing Chuanyi MFE10117260A005EH2725111S High-precision Electromagnetic Flowmeter
MFE10117260A005EH2725111S
The MFE Series High Precision Electromagnetic Flow Meter is designed for precise, reliable volume flow measurement of conductive liquids and slurries across industrial automation, chemical processing, and water treatment applications. Featuring an advanced signal processing architecture, broad line size coverage (DN2 to DN2400), and robust anti-interference performance, it offers high accuracy up to ±0.2% of reading with zero pressure loss and versatile digital communication protocols.
The MFE Series High Precision Electromagnetic Flow Meter is built on Faraday’s Law of Electromagnetic Induction to deliver exceptional measurement accuracy, long-term stability, and minimal maintenance overhead. Designed with modern process industries in mind, this magmeter features advanced high-frequency excitation and digital signal processing (DSP) to filter out process noise, ensuring smooth, highly dependable readings even under turbulent or pulsating flow conditions. With no moving parts or internal obstructions inside the measuring tube, the MFE Series creates zero pressure drop in your piping network while preventing clogging, making it an ideal solution for measuring aggressive acids, viscous slurries, wastewater, and high-purity media.
Constructed with high-grade wetted materials—including PTFE, PFA, ETFE, and various rubber liners, combined with Hastelloy, Titanium, Tantalum, or Platinum electrodes—the MFE Series is highly resistant to severe chemical corrosion and abrasive wear. The system offers versatile mechanical configurations, including compact (integral) and remote (split) designs with protection ratings up to IP68 for continuous submersion. To integrate effortlessly into modern distributed control systems (DCS) and SCADA environments, the MFE converter supports multiple signal outputs and digital communication protocols including 4-20mA, Pulse, HART, RS485 Modbus, Profibus-PA/DP, and FOUNDATION Fieldbus. Certified for hazardous locations with international explosion-proof standards, the MFE Series ensures operational safety and high performance across the most challenging industrial automation projects.
FAQ
Q: What is the required straight pipe run for installing the MFE Series flow meter?
A: Thanks to optimized magnetic field design, the MFE Series requires minimal straight pipe runs: a minimum of 5D (five pipe inner diameters) upstream from the sensor and 2D downstream.
Q: Can the MFE Series be installed in flooded or underground pits?
A: Yes. For submerged or underground applications, select the split (remote) sensor option with an IP68 protection rating, which allows the sensor to operate continuously underwater at depths up to 5 meters while the converter is installed in a safe, accessible location.
Q: How do I select the right lining and electrode materials for corrosive liquids?
A: Chemical compatibility depends on fluid concentration and temperature. Generally, PTFE or PFA liners paired with Hastelloy or Tantalum electrodes are recommended for strong acids and alkalis, while Polyurethane Rubber or Neoprene combined with Tungsten Carbide electrodes are preferred for highly abrasive slurries. Our engineering team can assist you in making the optimal selection based on your chemical data sheet.
Q: Is the meter suitable for non-conductive fluids like oil or pure alcohol?
A: No. Electromagnetic flow meters require a minimum fluid electrical conductivity of 5 μS/cm to generate a measurable voltage signal. Non-conductive media such as petroleum oils, diesel, or pure organic solvents cannot be measured by magmeters.
