Fundamentals of ultrasonic flow metering of natural gas

Natural gas custody transfer transit-time ultrasonic flow meters are multipath meters that use two ultrasonic transducers per path. The transducers are mounted through valves into the pipeline so that they are in acoustic communication with one another. That is to say, each transducer in the pair can receive ultrasonic signals transmitted by the other transducer in the pair, and vice-versa (see Figure 1).
