Alternatively, an off-line, bench-top viscometer can be used. Viscosity can also be measured indirectly by monitoring the amperage of the black liquor recirculation pump. (see post for Jan 18, 2009).

The viscosity of softwood black liquor is generally higher than that of hardwood. A viscosity of 200 cp and over is considered high. The range could vary between 30 cp (hardwood) to 220 cp (softwood), at 70% solids and 120 C at a shear rate of 250/s.
