摘要： A leakage from a liquid-transporting pipeline containing a liquid to be transported and being blocked into at least one block by block valves is detected by a system comprising a piping connected to the pipeline in parallel with anyone of block valves forming at least one of blocks in the pipeline, the piping being capable of passing the liquid to or from the block, a means for supplying the liquid to the block under a desired pressure through the piping, thereby maintaining the pressure of the liquid within the block as constant as possible, and further a means for measuring the amounts of the liquid passed to or from the block in the piping, thereby detecting a leakage of the liquid from the block, based on the measured amounts the liquid passed to or from the block.
