Computer-Based Acoustic Detector for Determining the Type and Concentration of a Solution

Abstract

The problem of determining the type and concentration of a solution is an important issue in food, medicaland chemical industries. In this paper, a work effort has been made to explore the possibility of designinga computer-based acoustic detector to determine the type and concentration of a solution. Signalconditioning and processing was carried out by using labVIEW (G Language) VIs. Experimental resultsshow that the produced acoustic signal frequency can be used as an informative parameter related withthe type and concentration of a solution. Also, linear range of measurement is found of 10g/100ml.Furthermore, acceptable results for common industrial applications are drawn with a maximum percentageerror of 3% compared with the conventional approach. As a result, such detector can be integrated withcontrol system in order to perform some control actions.
