Since the pressure fluctuation signals are masked by noise and can not be detected, the oil pipeline leakage detection method is not satisfactory on small leakage problem, without more accurate warning and location. This paper uses discrete wavelet…
In this paper, a method for leak detection in industrial pipelines during normal operation, is proposed. An accelerometer set on the surface of the pipe was used for the data acquisition. The system, via adapting filtering detects the frequency bands…
The paper describes two methods for detecting and locating leaks in long pipelines. The methods are based on an extended Kalman filter designed by lumping the non-linear Distributed Parameter (DP) system representing the pipeline system using the…

The paper is devoted to a new approach for condition monitoring of industrial equipment. Future high-quality methods of condition monitoring and defect locating have to be automatic, remote, apply universal methods and sensors, low cost and be…
The interface distribution of two-phase flow medium, i.e. flow pattern, greatly affects the operation characteristics of two-phase flow system. For example, the flow pattern of slurry mixed liquor in petroleum and metallurgical industries transported…
