Abstract: A coiled member measuring device includes a main frame fixedly anchored in relation to the outer casing or the coiled member handling device of a well and an inner housing supported by the main frame for unrestricted lateral movement in at least two different directions transverse to one another and in a common plane oriented perpendicularly to an axial direction of the outer casing. Followers in the inner housing surround an axial passage receiving a coiled member such as coiled tubing or continuous rod therethrough. Two adjacent followers are supported in a V-shaped pattern for sliding movement diametrically opposite a third remaining follower. Sensors associated with the followers permit determination of overall circumference and length of the coiled member.

Abstract: A tubing counter for counting coiled tubing inserted into a well includes an outer housing having a through passage for receiving the coiled tubing therethrough. In some embodiments, pressure rated connectors at both of the ends of the outer housing sealably connect the outer housing in series between the coiled tubing injector head and the outer casing of the well. A plurality of counting wheels are rotatably supported within the outer housing for rolling engagement along coiled tubing inserted through the outer housing while a counting mechanism records a number of rotations of each counting wheel independently of the other wheels to minimize counting errors. Locating the counter below the injector head and below the tubing stripper ensures that the tubing is cleaner and less likely to slip in contact with the counting wheels while also accounting for stretching of the tubing for more accurate measurement.
