  • Patent number: 11162643
    Abstract: A single-point dual sensor-based leakage method and system for a gas-liquid stratified flow pipeline includes a single-point dual sensor-based leakage formula for a pipeline to be detected; installing two sensors at the same point of one end of the pipeline, a signal collected by the bottom sensor being an acoustic wave propagated by liquid in the pipeline, and a signal collected by the top sensor being an acoustic wave propagated by gas in the pipeline; processing the two acoustic waves to obtain a time difference; and substituting the acoustic velocity in a gas and the time difference into the single-point dual sensor-based leakage formula. The installation of sensors at two ends of a pipeline, avoids missing detection of leakage acoustic wave signals by a single sensor, reduces the number of installed sensors, and is low in cost, high in safety and strong in applicability to a gas-liquid stratified flow pipeline.
