The mixing of two immiscible phases is a process commonly seen in many industrial applications. Whether it is desirable (e.g. mixing of ingredients in chemical or food industry) or undesirable (e.g. sediments or contaminants in water purification) process, it has to be taken into consideration and a detailed description would be beneficial to any end product. This paper deals with a method for observing the volume ratio of two immiscible phases from the state of total separation to the state of a homogenous mixture using industrial Electrical Impedance Tomography (EIT) system ITS p2+. This paper also shows a great advantage in combining the EIT measuring method with a theoretically derived formula. It is used to calculate the concentration of a non-conductive phase in the final mixture using the initial and final conductivity values. The authors were also able to show a possibility to successfully use the formula in situations, where the initial conditions for it are not fully met.
Key words: Electrical impedance tomography / two phase mixing process / electrical conductivity / concentration
