SYSTEM AND METHOD FOR MONITORING MOTION OF CARBON DIOXIDE

PROBLEM TO BE SOLVED: To provide a carbon dioxide motion monitoring system capable of measuring accurate local pH of carbonic water into which carbon dioxide is dissolved by a non-contact method by injecting carbon dioxide gas into water into which a pH measurement indicator is mixed and expressing the injection of the carbon dioxide gas as a digital image, and further capable of acquiring information obtained by quantizing a state change including motion of carbon dioxide.SOLUTION: The carbon dioxide motion monitoring system includes: an observation water tank in which an integrated pH indicator is mixed with water and received; a carbon dioxide supply tank for injecting carbon dioxide gas into the observation water tank; a photographing part for photographing the observation water tank as a digital image or a video image; and an analysis part for acquiring information on the movement of the carbon dioxide or the motion of the carbonic water through a hue change of the digital image or the video image photographed by the photographing part. The analysis part discriminates between the carbon dioxide and the carbonic water in the image by comparing the hue of the digital image or the video image with a pH table and deriving a local pH value.
