The electronic lab develops specific instrumentation characterize the sizes, frequency and velocities of in two-phase flow structures. The research is in electronic circuits embodied with the latest generation of micro-controllers to develop digital capacitive sensors. These sensors are capable to work in conductive liquids as water and also in non-conductive liquids as oils. This circuit is the core of several instruments for gas-liquid flow such as: single wire probes capable to measure the void fraction in bubbly flows, flush probes capable to measure the liquid film thickness in annular and stratified flows, cross section wire capable to measure the bubble velocity in slug flows and also other type of non-intrusive probes to access the gas volumetric concentration. The electronic lab activities include circuitry development, signal processing, data communication, micro-controller software development, sensor’s mechanical and electrical protection among other activities.
