L&W PERMEABILITY METER

SWEDEN — Lorentzen & Wettre’s felt permeability meter measures water permeability of press felts during operation. This process allows for the easy discovery of clogging and wear, making it possible to optimize pressing with regards to paper quality and dewatering.

The meter can also be used to optimize the conditioning system, as well as for quick troubleshooting. The instrument is smaller and lighter than its predecessor and includes position detection of both MD and CD. A new software, L&W Multiview 3D, can display 2- and 3-dimensional images of water permeability variations in felts, as well as including frequency analysis of machine directional data and report of the felt length.

“A paper machine standing idle is expensive,” notes Lars Knge, product manager of L&W felt permeability meter. “A large paper machine not producing can cost in the order of ?20,000 per hour. To reduce unplanned stops, this is very important. Using L&W felt permeability meter on a regular basis makes it easy to find weak points in the press section, thus enabling you to take the right action at the right time,” Knge says. “A two hour per year reduction in unplanned machine downtime could mean that the investment in an L&W felt moisture meter has paid for itself. Control of the process delivers a return on investment.”
