Magnetoflow® Model Magnetoflow Technical Mag Meter Flanged Brief GENERAL Badger's Magnetoflow line is the result of 35 years of research and field use in electromagnetic flow meters. Based on Faraday's law of induction,these meters can measure almost wF_ any liquid, slurry or paste that has a minimum of electrical conductivity. Designed, developed and manufactured under the strictest quality standards, the Magnetoflow meter ranks among the best in the market.Its sophisticated,processor based signal conversion represents the state of the art in the industry with accuracies of 0.25%or better.The wide selection of liner and electrode materials insures maximum compatibility and minimum maintenance over a long operating period. OPERATION The flow meter is basically a stainless steel tube lined with a nonconductive material. Outside the tube two DC powered electromagnetic coils are positioned diametrically opposing each other. Perpendicular to these coils, two electrodes are inserted into the flow tube. When the coils are energized, a Magnetoflow®Flanged magnetic field is created across the whole diameter of the pipe. When a conductive fluid flows through this magnetic field, a voltage is induced across the electrodes.This voltage is di- FEATURES rectly proportional to the average flow velocity of the fluid and is picked up by the two electrodes.This induced voltage is then • 0.25% accuracy independent of fluid viscosity, density amplified and processed digitally by the converter to produce a and temperature very accurate analog or digital signal.The signal can then be • Unaffected by most solids contained in fluids used to indicate flow rate, totalization or to communicate to .

Badger Meter's Magnetoflow Mag meters have an APPLICATION "Empty Pipe Detection" feature.This is accomplished by the use of a third electrode that is positioned between 12 o'clock Because of its inherent advantages over other more conven- and 1 o'clock in the meter.
