Abstract
Device for ultrasonic inspection of a wall of a pipeline that encloses a fluidum. The device is arranged to be moveable along a device axis through the pipeline along a longitudinal direction of the pipeline. The device is provided with electronic means, a body, a transmitting transducer and at least two receiving transducers, mutually spaced apart in a first transducer array along an array direction that is directed substantially parallel to the device axis. The electronic means are arranged to operate the transmitting transducer for transmitting a first ultrasonic signal to propagate through the fluidum to reach the wall, and to operate the at least two receiving transducers for receiving a second ultrasonic signal, which originates from the first ultrasonic signal after it is modified by the wall, according to a tandem method. The at least two receiving transducers are operated for receiving substantially simultaneously.
