摘要： The invention relates to a sensor device and a method for investigating a flexible hollow element having an inner surface for interfacing a liquid or a soft medium, the sensor device comprising: - a support (2) to be attached to the flexible hollow element (100); - attachment means (6) for attaching the support (2) to the flexible hollow element (100); - at least one transmitter (3) arranged on the support (2) for exciting acoustic waves in the support (2); - at least one receiver (4, 4a, 4b) arranged on the support (2) for receiving acoustic waves evoked by the transmitter (3), wherein - a signal generated by the receiver (4, 4a, 4b) upon receipt of acoustic waves evoked by the transmitter (3) can be evaluated to verify whether a coating (5) is present between the inner surface (1001) of the flexible hollow element (100) and the medium (7) and/or if a coating (5) is present to determine properties of the coating.

摘要： The invention relates to a method for investigating a structure and a structure for receiving and/or conducting a liquid or soft medium, the method comprising the steps of: a) exciting acoustic waves in the structure by means of at least one transmitter (3), b) converting at least a part of the energy associated with the acoustic waves (A) excited in the structure (2, 2a, 2b) into volume sound waves (B) of the medium (5), c) reconverting at least a part of the energy associated with the volume sound waves (B) into acoustic wave energy of the structure (2, 2a, 2b) thereby generating acoustic waves in the structure (2, 2a, 2b), d) receiving acoustic waves evoked by the transmitter by at least one receiver (4, 4a, 4b), and e) verifying whether a coating is present on a surface of the structure and/or if a coating is present determining properties of the coating by evaluating a signal generated by the receiver (4, 4a, 4b) upon receipt of acoustic waves evoked by the transmitter (3) and/or verifying whether a level of the medium (5) is below a predetermined value.
