IFLO series, featuring advanced Electromagnetic Flow meter-Remote solutions designed for high-performance, high-reliability volumetric flow measurement of conductive liquids and slurries in closed pipes. These instruments are indispensable across a wide range of industries, including steel, electricity, petroleum, chemical, coal, metallurgy, papermaking, water supply and drainage, food, and pharmaceuticals. The IFLO Electromagnetic Flow meter-Remote offers the flexibility of a split-type configuration, allowing the converter (display and electronics) to be installed separately from the sensor, which is ideal for applications with limited space, harsh environments, or where convenient remote monitoring is paramount.
Understanding the Technology: The Working Principle
The IFLO Electromagnetic Flow meter-Remote operates based on Faraday’s law of electromagnetic induction. The sensor component consists of a measuring tube with an insulating lining, a pair of electrodes mounted on the tube wall, and coils that generate a working magnetic field. As a conductive fluid passes through this magnetic field in the measuring tube, a voltage signal directly proportional to the average flow rate of the fluid is induced across the electrodes. This signal is then amplified and processed by the remotely located converter to provide various display and output functions.
Key Features of the IFLO Electromagnetic Flow Meter-Remote
The IFLO series, including the Electromagnetic Flow meter-Remote models, offers a robust set of features:
- Unaffected by Fluid Properties: Measurements remain accurate regardless of variations in fluid density, viscosity, temperature, pressure, and conductivity.
- Minimal Pressure Loss: The absence of obstructing components in the measuring tube ensures no pressure loss and reduces the requirements for long straight pipe sections.
- Clear Remote Display: The LCD backlight type converter, which can be part of the Electromagnetic Flow meter-Remote system, ensures easy readability even in direct sunlight or dark environments.
- Versatile Output Signals: The system supports multiple output forms crucial for remote monitoring and control, including current (4-20mA), pulse, frequency, RS-485, and HART protocol. Profibus DP is also available as an option.
- Bidirectional Measurement: Equipped with a bidirectional measurement system, it features three built-in totalizers for positive total, reverse total, and total difference.
- Advanced Diagnostics: The converter includes self-diagnosis alarm output, no-load detection alarm output, flow upper and lower limit alarms, and2 other alarm functions for reliable operation.
- Suitability for Demanding Applications: These meters are not only for general processes but are also adept at measuring challenging media such as ore pulp, mud, coal slurry, paper pulp, and paste liquids.
- High-Pressure Resistance: Models with PFA lining technology are resistant to high pressure and negative pressure, making them particularly suitable for petroleum and chemical industries.
- Explosion-Proof Options: Explosion-proof certified instruments are available for use in hazardous locations.

Selection and Configuration
Choosing the appropriate IFLO Electromagnetic Flow meter-Remote involves considering several factors:
- Liquid Conductivity: The liquid must be conductive, generally greater than 5 μs/cm.
- Flow Rate: If the medium contains solid particles, a flow rate of 1-3m/s is recommended. For pipelines with sediment, 2-5m/s is advisable.
- Lining and Electrode Materials: Selection is based on the temperature, corrosiveness, and abrasiveness of the medium.
- Lining options include PTFE (for strong corrosive media), PFA (similar to PTFE, strong negative pressure resistance), F46 (low abrasion resistance), Neoprene (good for water, sewage, weakly abrasive mud), and Polyurethane rubber (excellent for strong abrasive slurries).
- Electrode materials range from SUS316 (industrial/domestic water, sewage), Hastelloy B/C (for specific acid conditions), Titanium (seawater, oxidizing acids), Tantalum (excellent corrosion resistance similar to glass), to Platinum-iridium alloy and stainless steel coated with tungsten carbide (high abrasion).
- Structure: For an Electromagnetic Flow meter-Remote, select the “Split type (ER)” structure.
- Output Type: Choose the output that best suits your remote communication and control system (e.g., MA for Modbus, MB for HART, MF for GPRS wireless).
The IFLO pipeline electromagnetic flow meter selection table allows for detailed customization, including nominal diameter, pressure, lining material, electrode material, connection method, body material, housing protection, explosion-proof rating, structure (Integrated EH or Split ER for Electromagnetic Flow meter-Remote), power supply, and output type.
