From the early 1980's the petrochemical sector has invested in process tomography to provide information on multi-phase flows. As noted above, this is an extremely challenging measurement objective and it is only recently that significant advances in software, sensors and instrumentation technology have led to process benefits.

Multiple modalities (of capacitance and resistance tomography) have been fused to provide information on three phase flow. Resistance tomography provides data on water / oil-gas components and capacitance provides data on water-oil / gas components. By taking data contemporaneously, full three phase flow information can be provided, such as air/oil/water.

At a simpler level of instrumentation, robust sensors have been deployed in marine applications (in deserts / beaches) to provide information on solids flowing during dredging applications
In addition, advances in cross-correlation have combined with advances in very high speed data collection to provide the cornerstones for mass flow measurement.
