Beschreibung
Zusammenfassung:	A data acquisition system for determining the state of a tubular while the tubular rotates about its cylindrical axis. The tubular remains otherwise substantially stationary. Sensors travel up and down the length of the rotating tubular, interrogating the inside and outside of the tubular for data regarding the tubular's state. Sensors may take samples which may be associated with rotational reference information tying the sample to its absolute position on the internal or external surface of the tubular. A data processor processes the samples and other sensor data to produce a wide array of output, including data signatures of the tubular, maps of contour data regarding the internal or external surface of the tubular, and dimensional data regarding the tubular. Data acquisition is advantageously done in real time, and may further be done concurrently with internal or external cleaning operations.
