Liners in metal pipes electrically insulate the fluid from the pipe, allowing accurate flow measurement.

No single liner technology can be used for the entire range of nominal diameters from DN2 to DN2000, and each customer application is unique.

4 different liner materials: rubber, polyurethane (PU) and two different fluoro plastics – polytetrafluoro ethylene (PTFE) and perfluoroalkoxy (PFA).

Rubber liner exhibits good chemical resistance against water and alkaline solutions, but is not suited to oils or acids and fails to meet the hygienic requirements of the food and pharmaceutical industries.
