ABSTRACT:
The internal diameter measuring apparatus comprises a flexible supporting member capable of being inserted into a heat transfer tube in a nuclear steam generator with flexible centering devices disposed on the flexible supporting member at various locations along the flexible supporting member for centering the measuring apparatus within the heat transfer tube. The measuring apparatus also comprises contacting apparatus disposed on the flexible supporting member for contacting the inside surface of the heat transfer tube that is capable of deflecting in response to variations on the inside surface of the heat transfer tube. The contacting apparatus is connected to a transforming mechanism disposed in the flexible supporting member for monitoring the deflection of the contacting apparatus and for transforming the so monitored deflections into readings indicating the internal diameter of the heat transfer tube.
