Emerson has released new PEX liners for its Rosemount flowmeter portfolio to improve durability and reliability in chemically harsh conditions.
Flow meters measure the volumetric flow rate of liquids and gases. These tools are common across mining and processing operations to monitor, control, and optimize critical processes.
Emerson says current liner solutions have relatively poor abrasion resistance — a problem the new PEX liner is trying to solve. When liners degrade, they can release unwanted chemicals, such as polyfluoroalkyl substances (PFAS).
PEX liners are designed exclusively for use with the 8750W, 8705 and MS flanged magnetic flow meter sensors, and are made without PFAS-based materials. The company said this manufacturing decision was made “to help end users respond to increased regulatory, environmental and public scrutiny.” PEX liners typically remain “less expensive than alternative solutions,” Emerson added.
The liners are currently available in sizes up to 8 inches, with larger products in development.
