METHOD AND INSTRUMENT FOR MEASURING BUBBLE DIAMETER IN BUBBLE CONTAINING LIQUID

摘要

PROBLEM TO BE SOLVED: To accurately measure a bubble diameter even in a turbid bubble containing liquid, and to easily measure also a bubble diameter distribution of the bubble containing liquid.;SOLUTION: This method/instrument is provided with a suction pipe 1 having a fixed opening cross-section with a tip connected to the bubble containing liquid of the mixed solution, a mixed solution feed pipe 1a connected to the suction pipe 1 and a next measuring tube selection valve V1, the selection valve V1 for selecting a kind in a bubble diameter measuring tube 2, and the plurality of bubble diameter measuring tubes 2a, 2b, 2c of different tube inside diameters connected to the selection valve V1. A suction pump P is arranged in series to suck the mixed solution in order into an equipment to be feed it, and an image photographing device 4 connected to a data processor 5 having an image processing function is provided in the bubble diameter measuring tube 2.;COPYRIGHT: (C)2004,JPO
