摘要

Apparatus for determining a thickness of a wall of a pipe, featuring a signal processing module configured to respond to signaling containing information about traveling stress waves transmitted to and reflected back from a wall of a pipe by a sensor band that includes a series, ring or array having multiple transducers circumferentially arranged and mounted around, and attached to or clamped onto, an outside wall of the pipe; determine a profile of a thickness of the wall of the pipe corresponding to circumferential locations of the multiple transducers based on the signaling received from the sensor band, and the provides corresponding signaling containing information about the profile of the thickness of the wall of the pipe; and another module configured to receive the corresponding signaling and provide a visual indication of either data or a graph of the thickness of the wall of the pipe.

1. Apparatus for determining a thickness of a wall of a pipe, characterised in that the apparatus comprises:
a signal processing module configured to
respond to signaling containing information about traveling stress waves transmitted to and reflected back from an inner surface and an outer surface of a wall of a pipe by a sensor band that includes a series, ring or array having multiple PVDF transducers circumferentially arranged at angular positions and mounted around, and attached to or clamped onto, the outer surface of the wall of the pipe, the signaling being generated over a period of time by each of the multiple PVDF transducers in the sensor band that transmits respective traveling stress waves and senses reflections of the traveling stress waves transmitted that are reflected back from the inner surface a certain time later than from the outer surface at each circumferential location of a respective one of the multiple PVDF transducers,determine a time-based trending profile of a thickness of the wall of the pipe corresponding to circumferential locations of the multiple PVDF transducers as a function of the angular position and the period of time, based on the signaling received over the period of time from the sensor band, andprovide corresponding signaling containing information about the time-based trending profile of the thickness of the wall of the pipe using a self-reference approach where the difference in time between the reflections of the traveling stress waves being reflected back from the inner surface and the outer surface is proportional to the thickness of the wall of the pipe; and another module configured to receive the corresponding signaling and provide a visual indication of the time-based trending profile in the form of either data or a graph of the thickness of the wall of the pipe.
