1. A method comprising:
controlling a flow into or out of a conduit to induce at least two positive pressure waves of at least two negative pressure waves in the conduit using a pump or pressure wave inducement source;
measuring, with a pressure transducer, pressure responses in the conduit due to contact of the at least two positive pressure waves or at least two negative pressure waves with a geometric feature of the conduit; and
identifying the geometric feature, based on differences in the pressure responses from the at least two positive pressure waves or at least two negative pressure waves.
