Rosemount 8705 Flanged Magnetic Flow Meter 8705THA030S1W3N5G6

The Rosemount 8705 Flanged Magnetic Flow Meter is a high-performance electromagnetic flow measurement device designed for accurate and reliable flow monitoring in industrial applications. This model, 8705THA030S1W3N5G6, features a 3-inch line size with PTFE lining and Hastelloy C-276 electrodes, making it ideal for conductive liquids in industries such as water/wastewater, chemicals, food and beverage, and pharmaceuticals. It utilizes Faraday's law of electromagnetic induction to measure volumetric flow rates without moving parts, ensuring minimal pressure drop and long-term durability. Key benefits include high accuracy (±0.25% of rate), excellent resistance to corrosion and abrasion, and easy integration with control systems via integral transmitter mounting. Compared to similar products like vortex or ultrasonic meters, the 8705 excels in handling slurries and dirty fluids with low maintenance needs, though it requires conductive media (minimum 5 µS/cm) and may not suit non-conductive fluids. Its robust carbon steel flanges (ASME B16.5 Class 150) support pressures up to 275 PSIG, and it operates in temperatures from -20°F to 350°F. This brand-new unit from 2022 includes original packaging and documentation, offering superior signal stability and diagnostic capabilities for process optimization.
