L&W Felt Permeability Meter quickly and accurately measures the water permeability of press felts during operation. By measuring the water permeability of the felts, clogging and wear are easily discovered and the potential to optimize the pressing with regards to paper quality and dewatering is made possible. The instrument also measures felt length as well as giving measurement positions in relation to the machine width. The instrument can be used to optimize the conditioning system as well as for quick troubleshooting. L&W Permeability Meter is both smaller and lighter than its predecessor and includes position detection of both MD and CD, 2- and 3-dimensional images of the felt permeability as well as a frequency analysis conducted on all measurement results. Regular measurements with L&W Felt Permeability Meter lead to optimized use of cleaning chemicals, increased felt life, efficient dewatering, high and uniform product quality and reduced machine downtim.
