CD Basis weight Control System makes use of low frequency pulse adjusting dilution pump to feed white water in the same pressure condition. The dilution valves will respond to the signals from the dry end scanner.
In high basis weight areas the valves will open up further automatic, diluting the HeadBox stock in that zone. Oppositely, in low basis weight areas the valves will close a little automatic. Adjusting the location CD basis weight and improving the CD basis weight of the whole sheet.
