ABSTRACT:
A device being used for measuring the internal diameter of a pipe, which including a tape mounted into a flat elongated body having holes to allow a string to be pulled out of the flat elongated body. The tape includes hole at a first end for connecting a first end of an elastic band and the string to the tape. The flat elongated body includes a tongue having hole for connecting a second end of the elastic band. The string pulls the tape out of the flat elongated body for measuring the internal diameter of the pipe. The tape includes also hole at a second end for connecting a circular member keeping the device at a right angle in bottom of the pipe when reading the diameter of the pipe with the inspection camera, and also blocking the tape at the input of the flat elongated body when the elastic band bringing the tape into the elongated body.
