The OPTIFLUX 4000 is a fully welded, full-bore electromagnetic flow sensor for the process industries, including chemical, pulp and paper, water, minerals and mining, metals, pharmaceutical and oil and gas. It handles demanding duties such as corrosive and abrasive media, high-solids slurries, acids and alkalis, black liquor and high-pressure water injection, with engineered constructions available for customer-specific requirements. The sensor pairs with IFC 050, IFC 100, IFC 300 or IFC 400 converters and, with the IFC 300, is suitable for custody transfer.
