Document Type and Number:
WIPO Patent Application WO/2017/208645
Kind Code:
A1
Abstract:
The present invention enables improving the precision of measurement of liquid flow volume and the reproducibility of measurements. This flow volume measuring device is provided with: a light source which emits light on to a site to be measured; a light receiving element which receives scattered light that is resultant light emitted from the light source and scattered at the site to be measured; a contact member which has translucency with respect to both the wavelength of the emitted light and the wavelength of the scattered light, and which has a surface disposed opposite to the site to be measured such that the site to be measured can be brought into contact with the entire extent of said surface; and a flow volume measuring unit that measures, on the basis of the scattered light, the flow volume of a liquid flowing at the site to be measured.
