The objective of the present study is to develop a miniaturized impedance sensor probe, applicable to a wide range of two-phase flows, to obtain the time-averaged local two-phase flow parameters. This work describes a novel needle probe measuring system based on impedance measurements for two-phase flows composed by one sensing needle. This miniaturized needle probe can be employed for the investigation of dynamic processes in two-phase flow mixtures, virtually providing the most important time-averaged local parameters. Benchmark experiments employing the high speed image analysis method have been performed. The results from the benchmark experiment assess both the measurement principle and signal processing scheme of the newly developed probe method.
