PROBLEM TO BE SOLVED: To exactly measure the pressure and velocity of a gas in gas/liquid two-phase flow flowing in the state that gas and liquid are mixed. SOLUTION: In the pressure measuring device measuring the gas pressure of a gas/liquid two-phase flow flowing in the state that gas and liquid are mixed, a pressure pot which a first opening for introducing pressure is provided on the side surface and a second opening for extruding pressure is provided on the upper surface and is capable of storing liquid flowing in from the first opening and a pressure measuring apparatus for measuring pressure, by connecting with the second opening of the pressure pot, are provided. Even in the case liquid included in the gas/liquid two-phase flow is mixed in from the first opening, the liquid stays at the bottom of the pressure pot and will not mix in the second opening provided on the upper surface of the pressure pot. Thus, clogging of the first and the second openings is never been caused by liquid included in the two-phase flow, and the pressure of the two-phase flow can be measured exactly.
