Application of Ultrasonic Flow Meter in Detecting and Locating Ship Pipeline Leakage

Ship pipeline leakage can be detected and located by utilizing ultrasonic flow meter based on negative pressure waves and flow equilibrium method.An experiment platform was created on the basis of the operating principle and application characteristics of ultrasonic flow meter,the utilization of negative pressure waves in ship pipeline leakage and location system.Then the application of ultrasonic was verified,moreover,it showed that small leakage can be more easily detected and the frequency of false alarms during the normal operating of the pump valve can also be effectively decreased if ultrasonic flow meter based on negative pressure waves and flow equilibrium method was utilized in ship pipeline leakage detection and location,thus the practical applicability and feasibility of this method were demonstrated.
