いという欠点があった。Conventionally, the method of detecting fluid leaks is to directly detect the fluid, and the leakage method is to directly detect the fluid. Highly accurate detection of leaks and their locations has the drawback of being difficult to detect because it largely depends on the installation location of the detection device.

When using transmitted waves or reflected waves, by installing transmitters and receivers at two fixed locations, it is possible to inspect the site directly and monitor it constantly. In the case of simple piping, due to the reflection of radio waves,
Leak positions can be easily and accurately measured.
