METHOD OF MEASURING PARAMETERS OF OUTFLOW GAS FROM PIPE OF UNDERWATER GAS PIPELINE BY HYDROLOCATOR Russian patent published in 2017 - IPC G01S15/00 

FIELD: measuring equipment.

SUBSTANCE: method of measuring the volume of the outflow gas from the pipe of the underwater gas pipeline by the hydrolocator contains the radiation of the probing signal, the reception of the echo signal, the distance measurement, an echo is detected that exceeds the threshold in each channel, the time of the beginning and the time of the end of the echo in each spatial channel are determined, the channel with the maximum delay time and the corresponding minimum delay time is chosen, the distance at the end of the echo is calculated, the distance of the beginning of the bottom reverberation is determined, the depth of the bottom is determined with the help of the echo sounder, the angular position of the source of the gas leak is determined, the depth of immersion of the source of the gas leak is determined, and the volume of the outflow gas from the underwater gas pipeline is calculated from the obtained data.

EFFECT: ensuring the detection and classification of the gas leakage source of the underwater gas pipeline, locating the gas leakage object and determining the volume of the outflow gas.
