The objective of this work was the design, manufacture and validation of an acoustic monitoring system of the chemical analysis process, in order to alert the operator of the Belec Compact Port HLC® portable equipment used in the analysis of chemical composition in the field about the validity of the results. In order to investigate the effect of vertical distance and surface geometry factors in the results of the analysis of the chemical composition of API X65 steel a complete factorial design 3x8 was proposed. The Analysis of Variance (ANOVA) was applied, and it was concluded with a 95.45 % confidence level that the investigated factors (vertical distance and geometry of the evaluated surface) and the interaction between them prod...
