Finding interfaces among liquids in a process tank is crucial in some applications. Various industrial sectors have deployed expensive, invasive, and hazardous techniques to achieve this. In this paper, an Electrical Resistance Tomography (ERT) technique comprises a phantom tank surrounded by 16 copper electrodes. A 50 kHz, 5 mA AC signal was used as an input, and the output response in terms of voltages was fed to EIDORS reconstruction algorithm. The 2D images show the domain containing two poorly conducting liquids, i.e., water and oil, although not accurate, but showing ERT as a possible promising technique for analyzing liquid-liquid interfaces.
