You might contact manufacturers of online diameter gauges, some are mentioned in the Tube '96 report. See at: http://www.ndt.net/buyers/twd_96/twd_r.htm ....... Laser diameter gauges were very prominent at the show. This technique for inline diameter control is rapidly increasing in popularity, and we saw Laser Mike* at the crowded booth of Beta Instruments (specialists in UT and laser techniques)...... Laser diameter gauges are cheaper than UT but cannot find internal defects. Ultrasonic flaw detection in conjunction with diameter measurement technique is an applied technique and I personally did some work in this area. Inoex GmbH works in the field of equipment for online control in the plastic and cable industry (see NDTnet Exhibition) On NDTnet you may find more information at: http://www.ndt.net/article/rohrext/us_dia/us_dia_e.htm Chapter - Diameter measurement http://www.ndt.net/article/rohrext/us_ndt/us_ndt_e.htm Chapter - Ultrasonic Flaw Detection (Ultrasonic testing in Plastic Pipe extrusion) http://www.ndt.net/article/report/seattle/seattl_r.htm#10 .......A New Generation of Ultrasonic Systems for Dimensional Measurement of Tubing.
