Title:
DEVICE AND METHOD FOR DETECTING FINE PARTICLES IN FLUID
Document Type and Number:
WIPO Patent Application WO/2012/011420
Kind Code:
A1
Abstract:
A device and a method for detecting fine particles in fluid can efficiently and highly accurately detect fine particles in high-pressure fluid. The device for detecting fine particles in fluid is provided with a fluid supply section (13) to which fluid to be measured is supplied; a reduced diameter flow tube (14) having one end connected to the fluid supply section (13) and having a flow path reduced in diameter relative to the fluid supply section (13); and a fine particle detection means (15) connected to the other end of the reduced diameter flow tube (14) and detecting fine particles flowing into the fine particle detection means (15) from the reduced diameter flow tube (14). The method for detecting fine particles in fluid has: a step for supplying, by a fluid supply section (13), fluid to be measured; a step for reducing the pressure of the fluid to be measured, the pressure of the fluid being reduced by causing the fluid to pass through a reduced diameter flow tube (14) having a flow path reduced in diameter relative to the fluid supply section (13); and a step for detecting fine particles contained in the fluid being measured, the fluid having been reduced in pressure.
