10.5 Additives Correction Factor

10.5.1

Additive Correction Function

This function refers to handling the different brands made from main material with 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.

(Note 1) Component 0 is the main component. Components 1 to 5 are the additives #1 to #5.
(Note 2) Sensitivity values for components #0 to #5 are to be registered for each of 10 brands.
Usually, the sensitivity value for main component s, 0 is set to "1.000." The sensitivity
values of typical additives are shown in Table 10.5.2. Register s1 to s5 referring to this
table. For the sensitivity values of additives other than the ones shown in Table 10.5.2,
please contact Toshiba. Whenever you send us a sample of additives, we can measure
their sensitivity values. Sensitivity values are measured in the same way as used for span
calibration for each of additives (measured density reading / density by manual analysis).
(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 component 0 (main
component) in weight.
