ABSTRACT:
A fluid volume measuring apparatus for measuring volume of fluid flowing out of a measured object includes a passage member that defines a measurement passage. The measurement passage is filled with fluid, which is capable of moving in the measurement passage in accordance with volume of fluid flowing out of the measured object. The fluid filled in the measurement passage forms a bubble. The passage member has a translucent portion in a predetermined measurement range, in which the bubble displaces in accordance with volume of fluid flowing out of the object to be measured. The translucent portion is formed of a translucent material. Volume of fluid, which flows out of the measured object, is measured in accordance with displacement of the bubble.
