DEVELOPMENT OF ELECTRICAL RESISTANCE TOMOGRAPHY (ERT) DATA ACQUISITION PROTOCOLS FOR CONDUCTIVE MULTIPHASE PROCESSES

This report describes a considerably low-cost improvement theory of existing data acquisition system for a 16-electrode Electrical Resistance Tomography (ERT). It comprises of electrical parts such as voltage measurement amplifier circuit and switching circuit. Quality of data acquired is crucial for future work of image processing which induced the importance of mentioned circuits. Experimentations are conducted on brine solution with different concentrations to classify lower and upper range of voltages for different applications as well as demonstrating the effect of different measurement protocols towards common mode voltages.
