Case 7519(2) ABSTRACT OF THE DISCLOSURE METHOD FOR MONITORING ACOUSTIC EMISSIONS A non-intrusive method for the determination of characteristics of slug flow in a multiphase flow pipeline comprising the steps of: (a) detecting the acoustic emissions from the pipeline in the ultrasonic frequency range by means of at least one sound transducer, the output from which is an analogue electrical signal, (b) converting the analogue signal to a digital signal, and (c) analysing the digital signal to determine the characteristics of the slug flow. The characteristics of slug flow which may be determined include distinguishing slug flow from wave flow, the frequency of slugging and the velocity and length of slugs. The method is particularly suitable for studying multiphase flow comprising oil, gas and water.
