ABSTRACT:
A method of determining the velocity of a stream in a vessel comprising the steps of: providing a first quantity of ultrasonic energy to a wall of the vessel at a first predetermined location so that the first quantity of ultrasonic energy induces a first compressional wave in the stream; sensing the first compressional wave at a second predetermined location along the wall, the second location being spaced from the first location by a distance that is at least as large as the distance required for the first quantity of ultrasonic energy to induce the first compressional wave in the stream; providing a second quantity of ultrasonic energy to the wall at the second predetermined location so that the second quantity of ultrasonic energy induces a second compressional wave in the stream; sensing the second compressional wave at the first predetermined location; determining a first amount of time elapsed between the providing of the first quantity of ultrasonic energy and the sensing of the first compressional wave; and determining a second amount of time elapsed between the providing of the second quantity of ultrasonic energy and the sensing of the second compressional wave.
