"Ornery" Phosphate Slurry Metered as Easily as Water!
Arrows indicate trou bief ree Foxboro Magnetic Flow Meters, installed at Swift & Company's Bartow, Florida plant between filtration and pre-mixing stages of their triple superphosphate process. Stainless steel flow "tubes" of meters are protected against erosion and corrosion by a durable plastic liner.

Swift & Company Measuring slurry is duck soup for two Foxboro Magnetic Flow Meters now used in the production of Swift & Company's Agricola plant food. Here's the story. The company w a s shooting for uniform pre-mixing a n d guality control. Needed w a s a n accurate means of measuring the flow of partially filtered phosphoric acid slurry. Orifice plates, or anything that restricted flow, eroded. Pressure taps guickly fouled. Even purged, long-cone Venturi t u b e s plugged! Solution? Electrical measurement with Foxboro Magnetic Flow Meters. Their smooth, pipelike interiors simply ignore the suspended phosphate solids. There's no erosion, no fouling. Two flush-mounted electrodes "pick u p " flow measurement . . . Foxboro Dynalog* instruments record it directly on a linear scale chart. And these records are accurate to 1% of full scale! Find out exactly how the Foxboro Magnetic Flow Meter works . . . how it can efficiently a n d accurately meter the "impossible" in your plant.
