“…The tracer used is a liquid with a refractive index dierent from that of the liquid used. The tracer is injected into the continuous liquid phase and its concentration is measured by detecting the liquid refractive index with local specic optical probes (Graindorge, Laloux, Girault, Martin, & Lef evre, 1996). These probes have a very thin sensing tip that includes a cavity crossed by the liquid phase and delimited by two walls (see Fig.…”

This article oers an overview of the instrumentation techniques developed for multiphase ow analysis either in gas/liquid or in gas/liquid/solid reactors. To characterise properly such reactors, experimental data have to be acquired at dierent space scale or time frequency. The existing multiphase ow metering techniques described give information concerning reactor hydrodynamics such as pressure, phases holdups, phases velocities, ow regime, size and shape of dispersed inclusions, axial diusion coecients. The measuring techniques are presented in two groups: the non-intrusive techniques that deliver global, cross-section-averaged or local data, and the intrusive probes that are dedicated to local measurements. Eventually some examples of multiphase instrumentation development are reported (trickle-bed and slurry bubble column at semi-industrial scale) in the renery or petrochemical area.
