The electro-void fraction meter (Capacitance type meter) was applied to high void fraction measurement with various shapes of flow conduits such as round, rectangular and rod-bundle geometries. The principle of the meter is that the electrical capacitance of a gas-liquid two-phase flow changes with the void fraction. High-frequency power supply enables to measure the electrical capacitance of the ion-exchanged water with even though conductivity as low as 1 
S/cm. It was confirmed by the air-water and steam-water boiling two-phase flow experiments that void fraction can be obtained in real time way. Void fraction ranging from 0 to 0.9 at maximum was successfully measured under steam-water boiling two-phase flow conditions of 2 MPa through 18 MPa pressure.
