概要
This study discusses what we can do for the condition monitoring of storage tanks by acoustic emission (AE) technique. We first introduce our attitude to the tank inspection by AE by and then the advanced method for source location of signal AEs detected by the AE sensors mounted on the terrace of annular plates. Emphasis is laid on the accurate locati on of integrity loss in the tank floor plates. At the last portion of this paper, we discuss drawbacks of conventional parallel-type AE monitoring system and propose a new casca de multi-sensing AE system which makes long term continuous monitoring possible.
