• For the investigation of three- or multiphase flows, which are of interest for instance in the chemical engineering or in oil extraction and processing, there are only few suitable measuring techniques. For this reason we have developed a high-speed complex admittance/permittivity needle probe. Such probes are able to distinguish the different phases or components of a flow by measuring the complex value of the electrical admittance/permittivity at a high data rate (up to 10,000 samples/s). The performance of the system as well as its ability to differentiate some organic substances has been analyzed. A preliminary time resolved experiment in a gasoline-air-water flow is also presented
