The simultaneous stream of two of more substances denoted as multiphase flow is commonly encountered in many industrial applications, among others in nuclear, chemical and petroleum industry. The monitoring of such flow is required to assure safety and/or efficiency of industrial processes and equipment. For this reason, in the past a number of sensors and instrumentation to monitor multiphase flow have developed and applied. Impedance sensors, in which the measurand causes a variation of an electrical property such as resistance or capacitance, are promising candidates for the measurement of flow parameters of multiphase mixtures.

In this talk, an overview on selected impedance-based measurement techniques and sensors applied to the measurement of multiphase flows with emphasis in the field of petroleum production is given. First, typical scenario of onshore and offshore oil production systems along with typical requirements on sensors and instrumentation are given. Then, different sensor and instrumentation developed at UTFPR are presented as well as some typical application is shown. Hence, beginning with simple impedance probes up to tomographic (multi-electrode) sensors will be described and discussed.


De SilvaMarco Jose da Silva received the Dr.-Ing. degree in Electrical Engineering from Dresden University of Technology, Germany, in 2008. From 2004 to 2009 he was a Research Associate with Helmholtz-Zentrum Dresden-Rossendorf, Germany. In Year 2010, he joined the Federal University of Technology-Parana (UTFPR), Brazil, as Assistant Professor. From 2013, he is an Associate Professor (tenured) at the Department of Electrical Engineering (CPGEI) and since 2016 he also is co-Director of the Multiphase Flow Center (NUEM) at UTFPR. His research interests include measurement technology, sensors, and instrumentation applied to fluid flow. He is the author of over 150 scientific international journals and conference papers and was granted 3 patents. Dr. Da Silva is Topical (Senior) Editor of IEEE Sensors Journal and Associate Editor of Journal of Sensors and Sensor Systems.
