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.
Highlights
The problem of determining the type and concentration of a solution is still an important issue in solution mining and chemical processing [1]
The work described in this paper presents the possibility of using an acoustic measurement in order to determine the type and concentration of solution
The speed of transmitted acoustic signal varies depending on the type of the medium filled in the chamber. This variation of speed is usually characterized by the frequency of created acoustic standing wave, when the distance between the two heads of stethoscope is constant
Summary
The problem of determining the type and concentration of a solution is still an important issue in solution mining and chemical processing [1]. The measurement and control of the amount of solute present is an important concern for food processors Another example is the utilization of ionic liquids which are finding widespread use as solvents in several applications, including biphasic catalysis, liquid–liquid extraction, and organometallic synthesis [2,3,4]. The literature review of existing measurement detectors or analyzers which are used to determine the type and concentration of a solution shows that this issue is still developing. This explains why research and development in this field is a viable continuous process. The work described in this paper presents the possibility of using an acoustic measurement in order to determine the type and concentration of solution
