Magnetic Flowmeters - As processors continually tighten their belts, new loop-powered magnetic flowmeters (sometimes called mag) are also showing up as a cost-cutting alternative to other measurement methods in the CPI. “Traditionally, magnetic flowmeters were the choice if there were solids involved because the design is free of obstructions,” explains Bob Harvey, director of sales and marketing with Yamatake America Inc. (Phoenix, Arizona). “But, being four wire devices, they were overlooked by chemical processors because of costly installation issues and hazard risks in chemical plants with explosive environments.”

“Mag meters are free flowing, so there are no issues with solids coming down the line, which reduces maintenance costs associated with older style meters that seize when jammed by solids,” says Harvey. “We have situations where people were spending $200 to 300 a couple times a year rebuilding turbine and other meters. Then they spend $1,800 to $2,100 on a two-wire mag, eliminate maintenance expenditures and the payback is fast.” He adds that the accuracy, ability to handle solids, reduced mechanical wear and reduced need for calibration can quickly provide further savings.
