METHOD AND APPARATUS FOR LEAK POINT DETECTION

A method of detecting a leak point (24) on a fluid line (18), the method comprising: while maintaining the fluid line (18) in a state in which the fluid line (18) is substantially filled with air at ambient pressure, emitting ultrasound (25) into the fluid line (18) using an ultrasound emitter (20); and detecting, using an ultrasound detector (22), that the emitted ultrasound (25) is exiting the fluid line (18) at the leak point (24) on the fluid line (18). 一种检测流体管线（18）上的泄漏点（24）的方法，所述方法包括：在将流体管线（18）保持在流体管线（18）基本上充满环境压力下的空气的状态的同时，使用超声波发射器（20）将超声波（25）发射到流体管线（18）中；以及使用超声波检测器（22）检测发射的超声波（25）正在流体管线（18）上的泄漏点（24）处离开流体管线（18）。
