In an effort to obtain a comprehensive knowledge of gas-liquid flows, in this paper the use of different tools available at the University of Nottingham to study gas-liquid flow in pipes is presented, followed by a comparison of the instrumentation performance. Air-silicone oil is used as the working mixture. The tools are capacitance wire mesh sensor (WMS), electrical capacitance tomography (ECT), capacitance probes and computational fluid dynamics (CFD) modelling. This is supplemented by illustrations of the sort of information that have been obtained. In general the agreement in the comparison is fairly good. However, it is observed that the WMS provides a better spatial resolution than ECT (with a first order reconstruction method) and is excellent for measurement of bubbly flow parameters.
