Basis Weight
Pulp stock consistency is a key factor in determining the grade and quality of the end product. Basis weight measured at the dry end of the
machine is fed back via control logic to the basis weight valve at the wet end of the machine. Appropriate adjustments can then be made to
produce an end product that meet’s customer specifications. This makes the basis weight valve one of the most critical in the mill.
Quick, accurate step changes to setpoint are a must. Response time must also be quick. Correct control logic between the course and trim
valves are necessary to ensure correct end product basis weight.
