10.5 Additives Correction Factor

10.5.1

Additive Correction Function

This function refers to handling the different brand of the pulp which contains various additives. If the
physical property of the measured object fluid varies, it is necessary to set the density multiplier for a
value appropriate to this difference. Even with multiple types of measured objects mixed together
(mixed fluid), if their compound ratio is regarded to be consistent, it is possible to measure the density
of the entirety or the density of a particular type among them. In measuring the density of such mixed
fluid, each time the physical property and compound ratio of the objects included in the fluid differ (that
is, the brand is different), it is necessary to set the density multiplier in accordance with the brand of the
relevant mixed fluid.
By selecting an applicable brand number from about ten brands registered in advance, this additive
correction function calculates the density in accordance with the brand, thus making it possible to omit
the span calibration in terms of each brand.
Using this function in a simplified manner, by selecting the span calibration factor(density multiplier) in
terms of each brand from the brand list registered in advance, it is possible to simplify the span
calibration. For information on the simplified way of this function, refer to "10.5.5 Simplified way of
using the additive correction function".
● The contents to be registered into the brand list are as follows.

Comp. 0 (pulp)
Comp.1

Comp.3
Comp.4
Comp.5
(Note 1) Component 0 is the main component pulp. Components 1 to 5 are the additives #1 to #5.
(Note 2) Sensitivities for components #0 to #5 are to be registered for each formula of the 10 brand
list. Usually, the sensitivity, s0 for pulp, is set to 1.000. The sensitivities for typical
additives are listed in table 10.5.2. For other additives, please contact Toshiba, we
measure the sensitivity when you provide us with a sample of an additive. A sensitivity is
measured in the same procedures for the off-line span calibration for an additive, from
(measured density reading/density by manual analysis).

Calcium carbonate
Titanium oxide
Zinc oxide
Talc
Note 3: For each formula in the list of 10 brand, the ratio of mixture for the components #1 to 5 is
to be entered. A ratio of mixture is a ratio of a component against the pulp (component 0)
in weight.
