2.2 How to calculate the sheet dryness
The solids on the forming fabric are calculated according to the TAPPI
methodology:
Sheet consistency: Solids on f. fabric / Mass on f. fabric
Example:
FiberScan™ total water reading =
5000 gr/m
2
FiberScan™ f. fabric water content reading =
150 gr/m
2
Solids on f. fabric =
100 gr/m
2
Mass on f. fabric = 5000 g/m
2
- 150 gr/m
2
+100 gr/m
2
=
4950 gr/m
2
% Dryness (consistency) = 100 gr/m
2
/ 4950 gr/m
2
=
2,02
