Abstract
A method and system are described for determining a wall thickness of an object such as a pipeline using ultrasound. A pig is used that includes at least one first ultrasonic transducer that is attached to the pig for transmitting ultrasound in the object. Using at least one second ultrasonic transducer, a receiving signal is generated representing reflections of the ultrasound on the object received by the at least one second transducer. The received signals are processed by a processor provided at the pig to obtain a compressed receiving signal. In use, the processor determines a maximal N peaks having largest amplitudes and associated information on a moment on which each one of the maximal N peaks occurs within the receiving signal. Information about the maximal N peaks and associated information on the moment on which the maximal N peaks occurs is stored as the compressed receiving signal in a storing device of the pig.
