<p><P>PROBLEM TO BE SOLVED: To provide a fluid leakage detection system for a marine hose, capable of promptly detecting fluid leakage of the marine hose and acknowledging a degree of leak amount. <P>SOLUTION: When damage occurs from a fluid flow passage 1a to a fluid residence layer 7 due to failure of a first reinforcing layer 4, transportation fluid is flowed in the fluid residence layer 7 via the damaged portion and air pressure of the fluid residence layer 7 is immediately increased. Linked with the magnitude of the air pressure, a flexible tube 10 arranged inside the fluid residence layer 7 to be spirally wound around the fluid flow passage 1a is contracted and deformed. Via a communication tube 11, a diaphragm 14a of a pneumatic sensor 12 is properly fluctuated and a pressure detection part 14b performs detection. On a display part 15a of a receiver 15 receiving the detection signal, the air pressure of the fluid residence layer 7 is displayed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
