Abstract
An apparatus and method for determining the diameter of a pipe from a remote location is disclosed. A measuring assembly, including a reference device and an imaging device, is inserted into a pipe from a remote location. The reference device is inflatable to a predetermined and known diameter within the pipe. The imaging device acquires imaging data of the reference device within the pipe and the imaging data is used to determine the diameter of the pipe by comparing the predetermined diameter of the reference device with the diameter of the wall of the pipe. The diameter of the pipe is then used to properly choose a liner assembly of the same diameter to repair the wall of the pipe. The liner tube may include a bladder and liner tube, which is saturated with a curable resin, to repair the wall of the pipe.
