ABSTRACT:
An anvil in conjunction with an electromechanical probe measures across a tube while a second anvil and electromechanical probe measure across the tube at right angles to the first anvil and probe. Signals from each of the probes are summed and displayed to show the ovality of the tubing. The anvils and probes are mounted to a head that is rotated open to permit placement over tubing and resiliently rotated closed to bring the probes in contact with the tubing.
