ABSTRACT:
A liquid-transferring hose of single-carcass configuration, with a rubber tube layer, main pressure-resistant cord layer and cover rubber layer, in this order from the inside, wherein a transponder installed between the rubber tube layer and cover rubber layer transmits and receives waves of specific frequency, which are attenuated by at least -60 dB when passing through liquid to be transferred, and transmits a response signal on receiving the above waves. This design prevents the response signal transmitted by the transponder, when it is covered with leaked liquid, from being detected, to tell occurrence of liquid leakage, allowing liquid leakage to be easily detected during the initial stage.
