ABB Electromagnetic Flow Meter — Overview

ABB Electromagnetic Flow Meters (Magmeters) are industrial instruments designed to accurately measure the flow rate of conductive liquids in pipes, using electromagnetic induction principles — with no moving parts in the flow path. These meters are widely used in water and wastewater treatment, chemical processing, pulp & paper, mining, food & beverage, energy, and industrial automation systems due to their precision, reliability and low maintenance needs.

�� Key Features & Benefits

✔ High Accuracy & Stability: Offers precise volumetric flow measurement even in turbulent or pulsating flows — typical meters deliver accuracies within ±0.2 % to ±0.5 % of reading depending on model.
✔ No Moving Parts: Because they rely on Faraday’s law of electromagnetic induction, there are no mechanical components in contact with the fluid — resulting in low wear, minimal maintenance, and long service life.
✔ Wide Pipe Sizes: Available for small and large diameters (from a few millimetres up to DN2000 or more) to fit diverse process piping.
✔ Advanced Diagnostics: Many ABB models include built-in diagnostics to detect empty pipe conditions, electrode issues, grounding problems, and flow abnormalities — improving reliability and uptime.
✔ Communication Protocols: Support for HART, Modbus, PROFIBUS, Fieldbus and other industrial communication protocols allows easy integration with PLC/SCADA and automation systems.
✔ Robust Construction: Sensors and transmitters are designed to withstand harsh environments, corrosive media and high-pressure service with options for PTFE, rubber or hard liners.

�� Typical Applications

• Water & Wastewater Treatment & Distribution — municipal water networks, sewer monitoring, district metering (e.g., AquaMaster series).
• Industrial Process Control — chemical dosing, cooling water systems, effluent monitoring.
• Food & Beverage Manufacturing — hygienic measurement of potable liquids and process water.
• Pulp & Paper and Mining — slurry, fiber-laden liquids where low maintenance is critical.
• Utilities & Energy — custody transfer, billing, flow accounting and system diagnostics.
