Gas leak location method based on annular ultrasonic sensor array

In order to resolving the problem of diagnosing gas leak, this paper presents a method based on annular ultrasonic sensor array targeted at gas leak location of cylindrical containers. The location of gas leak is based on a data fusion algorithm with acoustic intensity algorithm and time difference of arrival (TDOA). An ultrasonic gas leak location system is established by this method. The validity and correctness of this method are verified by experimental results.
