Foxboro 8500A Magnetic Flowmeter

8500A Magnetic Flowmeter

The Foxboro 8500A is a compact wafer-style electromagnetic flow sensor designed to deliver accurate, maintenance-free, and long-lasting flow measurement for conductive fluids in industrial and municipal applications. It is part of the Foxboro magnetic flowmeter series from Schneider Electric, widely recognized for field reliability, advanced diagnostics, and cost-efficient installation. The 8500A is uniquely engineered to serve users who require high precision in space-constrained systems, while still benefiting from the robust, non-intrusive technology of electromagnetic flow measurement. Unlike mechanical flowmeters, the 8500A contains no moving parts and is not affected by pressure, temperature, viscosity, or density changes—making it extremely well-suited for water, wastewater, slurries, and other conductive liquids. Its wafer-style body enables easy insertion between standard flanges, reducing meter weight, piping stress, and installation cost—especially important in OEM skids, retrofit installations, or plastic/FRP piping systems. One of the standout features of the 8500A is its compatibility with Foxboro signal converters (such as IMT30A, IMT31A, and IMT33A), which handle power, signal processing, output scaling, and diagnostics. When combined, they form a complete, intelligent flow measurement system capable of analog or digital communication, bidirectional measurement, and field diagnostics—making it suitable for both modern automation networks and legacy control systems.
