Split-Type Electromagnetic Flow Meter Overview

The split-type electromagnetic flow meter developed by Ecolor is a volumetric flow measurement instrument for conductive liquids, built around an aerospace-grade polymer measuring section and a separately mounted transmitter head. The measuring section is integrally injection-molded from LGF-PA66, a long glass fiber reinforced composite material, which gives the split-type electromagnetic flow meter excellent waterproof and corrosion-resistant properties while avoiding the magnetic interference typical of metal pipe sections. With a measurement accuracy of ±0.5% (DN50-100), IP68 protection for the split-type version and standard RS485 communication, the instrument is designed for flow measurement and control in chemical additives, sponge city projects, water supply and drainage, irrigation, water treatment, wastewater treatment, paper pulp, slurry, pharmaceutical raw materials and food processes, while its cost is only half of comparable domestic products. In agricultural irrigation projects it serves as an electromagnetic flow meter for irrigation — canal and well water metering with DN10-DN2000 sizing, ±0.5% billing-grade accuracy and optional solar-powered EC32 RTU telemetry.

Working Principle of the Split-Type Electromagnetic Flow Meter

The split-type electromagnetic flow meter operates on the principle of electromagnetic induction. When a conductive liquid flows through the measuring pipe, it passes through the magnetic field generated by the excitation coil, and a voltage is induced in the fluid in proportion to its average flow velocity. Electrodes embedded in the pipe wall detect this signal and send it to the transmitter head, where a self-developed advanced algorithm with fast response converts it into volumetric flow. Because the induced voltage depends on flow velocity alone, the measurement accuracy of the split-type electromagnetic flow meter is not affected by changes in fluid density, viscosity, temperature, pressure or conductivity. The measuring pipe contains no obstructing flow components and no moving parts, so the meter creates no pressure loss and places only low requirements on upstream and downstream straight pipe sections.

Key Features of the Split-Type Electromagnetic Flow Meter

Two core innovations distinguish this split-type electromagnetic flow meter from conventional metal-body designs: the composite measuring section and the integrated mold-casting construction.

  • The measuring section is integrally injection-molded from LGF-PA66 aerospace-grade long glass fiber reinforced composite with no welding process, fundamentally eliminating the inherent magnetic interference of metal pipe sections; the material can be customized per customer requirements.
  • Measuring electrodes are embedded directly during injection molding, providing excellent waterproof and corrosion resistance, while the seamless integrated structure of sensor and measuring section completely eliminates leakage risk.
  • The excitation coil adopts a modular structure that effectively reduces winding deviation, ensures stable product performance and supports quick replacement during maintenance.
  • A dual waterproof sealing structure combined with precision assembly delivers both excellent waterproof performance and the ±0.5% (DN50-100) high-precision measurement standard.
  • The CNC integrated forging process and IP68 protection allow the split-type electromagnetic flow meter to work stably in humid, submerged conditions and to withstand long-term exposure to high pressure and corrosive media.
  • The transmitter head offers stable repeatability and linearity, with self-diagnostic alarm output, empty-pipe detection alarm, flow upper and lower limit alarms and batch control, plus an LCD backlit display readable in direct sunlight or dark rooms.

Applications of the Split-Type Electromagnetic Flow Meter

In environmental protection projects, the split-type electromagnetic flow meter monitors sewage flow and industrial wastewater discharge, including chemical wastewater and electroplating wastewater lines, supporting discharge control. In urban pipeline networks, it provides real-time monitoring of water supply and drainage flow, offering reliable data support for pipeline operation, maintenance and leakage control, which also suits sponge city construction. In industrial scenarios such as chemical processing and food production, the split-type electromagnetic flow meter enables precise fluid measurement to optimize production, handling chemical additives, paper pulp, slurry, pharmaceutical raw materials and food-grade media. It also serves irrigation, water treatment and agricultural processes, and its suitability for various conductive liquids and solid-liquid two-phase flows keeps broadening the range of possible measurement points.

Installation and Maintenance of the Split-Type Electromagnetic Flow Meter

The composite measuring section makes the split-type electromagnetic flow meter lighter than traditional metal flow meters, which simplifies transport, installation and later maintenance, and its strong corrosion resistance suits harsh environments. In split-type installations the transmitter head can be mounted in a dry, accessible position while the sensor sits in pits, flooded chambers or submerged locations, an arrangement that suits the IP68-rated sensor particularly well. The modular coil design allows maintenance without complete disassembly of the instrument, significantly reducing operational costs, and excellent product consistency with minimal performance fluctuation during batch use reduces on-site calibration requirements. During commissioning, following the low straight-pipe-section guidance and confirming medium compatibility keep the split-type electromagnetic flow meter accurate and stable over a long service life.
