A double-sensor probe was used to measure local interfacial parameters of a gas-liquid bubbly flow in ahorizontal tube.The parameters included void fraction,interfacial concentration,bubble size distribution,bubblefrequency and bubble interface velocity The authors paid special attention to the probe design and construction forminimizing measurement errors.Measures were also taken in the design of sensor ends for preventing corrosions inthe flow.This is an effort to improve the current double-sensor probe technique to meet the ever-increasing needsto local parameter measurements in gas-liquid two-phase flows.
