METHOD FOR MEASURING DENSITY OF LIQUID USING MAGNETOSTRICTION

摘要

The present invention relates to a technology wherein, when the density of a liquid is measured using the principle of magnetostriction, an induction formula between two floaters is used such that the unknown density can be measured accurately. To this end, according to the present invention, a correction point reference value is stored in advance on the basis of an effective sinking distance between a liquid surface floater and a density floater, and, when the density of a liquid to be measured is obtained later using the correction point reference value, a graph indicating the relationship between the effective sinking distance and the density is applied to a non-linear graph, which is similar to reality, thereby obtaining a density having a high degree of precision.
