Abstract:
An ultrasonic flow meter suitable to carry a stratified flow in a two-phase flow, comprising:a first ultrasonic transducer capable of transmitting ultrasonic signals along a first path; a second ultrasonic transducer capable of transmitting ultrasonic signals along a second path; a third ultrasonic transducer capable of transmitting ultrasonic signals along a third path; to said first, second, and third paths being different, wherein said first path traverses a first portion of said two-phase flow generally corresponding to said first phase and reflecting off the surface of said stratified flow, and said second path traverses a second portion of said two-phase flow generally corresponding to said second phase prior to said second path reflecting off the surface of said stratified flow, and said third path remains completely in a single portion of said two-phase flow.
