  • In-situ ultrasonic measuring system for natural gas flux at the hydrocarbon seeps at the seafloor
    Patent number: 9845672
    Abstract: An in-situ and on-line acoustic measuring system for natural gas flux at the hydrocarbon seeps at a seafloor includes a seepage tent and a flow measuring channel. The flow measuring channel includes a lower bubble breaking channel, an ultrasonic transducer measuring channel and an upper bubble breaking channel. The lower bubble breaking channel communicates with the seepage tent provided with bubble breaking grids. Lower and upper bubble breaking devices, arranged in a bubble rising direction, are respectively mounted in the lower and upper bubble breaking channels. One side of the ultrasonic transducer measuring channel is fixedly connected with an acoustic wave demultiplexer, and the other side is fixedly connected with flat receiving transducers receiving transmitting acoustic waves generated by an acoustic wave branching unit.
