Abstract:
A hose arrangement (1) for transferring a flowable medium between a first unit (5) and a second unit (7). The hose arrangement comprises a hose unit (3) comprising a first conduit (20) adapted to transfer the medium, and a second conduit (22) arranged around the first conduit (20) so that a closed space (24) is formed. The hose arrangement comprises a loop arrangement (40) comprising an inlet (42) for injecting a gas into the space (24) and an outlet (44) for removing the gas from the space (24). The hose arrangement comprises pressure sensor means (80) and a logic unit (82) adapted to receive information from the pressure sensor means and in dependency of said received information determine a significant change in the pressure that is related to a malfunction of the hose unit in a start-up phase of the operation of the hose unit.
