Title:
EQUIPMENT FOR DIAGNOSING BLOCKAGE OF LEAD PIPE AND METHOD FOR DIAGNOSING BLOCKAGE
Document Type and Number:
WIPO Patent Application WO/2010/064629
Kind Code:
A1
Abstract:
A pressure transmitter detects the pressure of an object to be measured, such as liquid, slurry and gas, which has pressure oscillation, by way of a lead pipe. Equipment for diagnosing the blockage of a lead pipe comprises a section (11) which divides the time series of a pressure value detected by the pressure transmitter into a plurality of sections and detects the number of times of vertical oscillation on a section basis, and a section (12) which determines the blockage state of the lead pipe by comparing the number of times of vertical oscillation with a predetermined threshold.
