The research aimed to develop, construct, and evaluate a device for meticulously measuring voltage dynamics in wet circuits. This involved assessing fluctuating voltage levels at varying depths within specialized columns, revealing the intricate interplay between probing equipment and aquatic environments. Regression analysis highlighted a nuanced correlation between water levels and electrode voltage, particularly within the initial 10 cm of immersion. Key outcomes included the examination of materials suitable for sensor construction, such as crusted gold and cuprum, and the refinement of methodologies for electrode measurement and data transmission to central systems, with a focus on open channels. Utilizing these insights, a wet circuit was engineered to enhance the operational efficiency of sewage systems, allowing real-time monitoring of water quality and leak detection. The water level measurement device holds significant potential for widespread adoption in municipal facilities, offering streamlined monitoring capabilities and aiding in the optimization of sewage system integrity and functionality, especially in confined channels serving sewage and stormwater systems.
