The apparatus includes a passage member having a measurement passage being connected to the measured object at one end. The measurement passage is filled with liquid. The apparatus further includes a closed vessel, which is connected to an other end of the measurement passage and filled with saturated vapor of the liquid. The apparatus further includes an analyzer. The liquid filled in the measurement passage contains a bubble, which is movable in accordance with change in amount of the liquid in the measurement passage. The analyzer is configured to calculate a travel distance of the bubble and configured to measure the amount of the liquid flowing from the measured object based on the calculated travel distance.
