Non-Contact TDS Measurement by UV-VIS-NIR Spectrophotometric Analysis

Water being the most important for existence of life and hence there exists a need to monitor it on a regular bases with the rising need. In our experimentation setup efforts have been made to minimize the unknowns and provide a standard as per the basic laws and provide a suitable environment to obtain repeatable readings. Light of the incident wavelength can affect the excitation of electrons in the atomic or molecular ground state to higher energy levels, giving rise to an absorbance at wavelengths specific to each molecule. The purpose of this study is to provide better insights to actual deployment of sensing systems alongside further development in the domain where existing piping infrastructure is disturbed to a minimum. Sensing system developed aims to nullify the existing shortcomings and put forward a solution to inline contactless TDS measurement on a repeatable basis by using machine learning based computations. This will provide added advantages like very low maintenance cost, specific elemental analysis, and easy integration. Further discussion on challenges, and improvements for a wider application scope is discussed.
