This report presents a state of art of measurement technique of interfacial area concentration in a gas-liquid two-phase flow. Based on the conventional 4-sensor probe method, a simple algorithm was derived to measure bubble velocity assuming bubble shape. Measurement error in the bubble velocity and shape is caused by the interface curvature, which directly affects the measurement error of the interfacial area concentration. Correction method of interface curvature is shown to improve measurement accuracy of the interfacial are concentration.
