Abstract

A bubble measurement device for measurement of bubbles moving in a liquid is provided. The bubble measurement device includes a measurement chamber into which the liquid containing the bubbles to be measured is introduced from below the measurement chamber, and having an image capturing surface at a position where the introduced bubbles rise; an image capturing device configured to capture an image of the bubbles passing along the image capturing surface; an introduction pipe provided below the measurement chamber and configured to introduce the bubbles into the measurement chamber; a supply pump provided above the measurement chamber and configured to suck up the liquid containing the bubbles so as to supply the liquid into the measurement chamber; and a flow velocity adjusting mechanism configured to adjust a flow velocity of the liquid passing along the image capturing surface. The flow velocity adjusting mechanism adjusts the flow velocity of the liquid passing along the image capturing surface to be within a range in which the bubbles are measurable. The range is obtained in advance in accordance with an image resolution and a shutter speed of the image capturing device.
