Emerson has introduced new PEX liners tailored for its Rosemount™ 8750W, Rosemount 8705 Flanged, and Rosemount MS Magnetic Flow Meter sensors. These components are specifically engineered to handle water, wastewater, slurries, and highly abrasive environments.
By utilizing this new PEX material, operators gain a more durable, PFAS-free, and economical flow meter option that enhances reliability under harsh chemical conditions while streamlining regulatory compliance and inventory management.Traditional liner alternatives suffer from low durability when exposed to abrasive sludge or chemical wear, which causes them to release hazardous substances as they degrade.
Furthermore, these older options involve high purchasing and upkeep costs, frequently experiencing structural deformation (flaring) if the meters are stored for too long before installation or if they are temporarily uninstalled and put back into service. Managing inventory is also problematic with standard options because different processes demand unique liner types, escalating storage complexities and capital expenses.
To address these issues, Rosemount magnetic flow meters now provide a PEX liner option that is not available from other suppliers. This exclusivity enables end users to address per- and polyfluoroalkyl substances (PFAS) concerns and durability challenges, without changing measurement technology or suppliers.
PEX liners formulated without PFAS help end users respond to increasing regulatory, environmental and public scrutiny, while maintaining liner performance. This simplifies material selection and stocking compared to fluoropolymer-based liners, as the latter can differ in materials of construction, depending on the application.
The PEX liners’ crosslinked molecular structure delivers high abrasion resistance, making it suitable for wastewater, slurries, and other applications with entrained solids where liner wear can reduce product life. Even with all these advantages, PEX liners are typically less expensive than alternative solutions. PEX liners are available now for line sizes up to 8 inches, with liners for larger line sizes under development.
