1. A system for non-intrusively tracking an object in a conduit, the system comprising:
a vessel comprising a pressurized fluid;
a valve positioned to control a flow of the pressurized fluid into the conduit to induce at least one pressure wave directed at the object;
a pressure transducer in fluid communication with the conduit, the pressure transducer positioned to measure at least one pressure response in the conduit due to contact of the at least one pressure wave with the object; and
a system controller operable to:
receive pressure data from the pressure transducer, wherein the pressure data includes the at least one pressure response; and
determine a distance of the object in the conduit, relative to a reference point, based on the at least one pressure response.
