1. A method of measuring tube wall thickness, the method comprising:

  • loading a tube between a stationary member and a movable member;

    compressing the tube between the stationary member and the movable member;

    receiving a signal indicative of an amount of compression of the tube while compressing the tube;

    determining from the signal that the tube is fully compressed and stopping the compressing of the tube once the tube is fully compressed; and

    determining a thickness of the tube wall based on the signal received indicating full compression.
