PARTICULATE-MEASURING SYSTEM IN HIGH-PRESSURE FLUID AND PARTICULATE-MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a particulate-measuring system, capable of properly performing the cleaning and maintenance of the flow channel to a measuring part in measuring particulates inside a high-pressure fluid of 1 MPa or higher and capable of measuring the particulates themselves by a direct inspection method, and to provide a particulate-measuring method.;SOLUTION: In the particulate-measuring system in the high-pressure fluid, constituted so as to allow the high-pressure fluid to flow through a membrane filter 52 to measure the particulates captured by the membrane filter 52, a second bypass line 20 is provided to the membrane filter 52. Alternatively, a means for adjusting the pressure or flow rate of the high-pressure fluid is provided in the process, before the high-pressure fluid is allowed to flow through the membrane filter 52 and a first bypass line 16 is provided to the pressure or flow rate adjusting means.;COPYRIGHT: (C)2009,JPO&INPIT
