Re: inner pipe diammeter measurement You can use ultrasound, see: http://www.ndt.net/article/rohrext/us_dia/us_dia_e.htm

I believe that krautkramer or Panametrics deliver such system.

Fallon Ultrasonics sells pipe diameter measurements system having accuracy of 1 micron. System measures wall thickness (true and average), OD and ID (true and average) ovality and eccentricity. Data are displayed on chart recorded formate and very high speed. System are being used in nulcear industires with flaw system at surface speed of greater than 2 m/s. Please contact me if you need further information. For the measurement accuracy both sensor and system should able to respond to slight variation in positon of tube with repsect to sensor position.
