In-pipe leak detection systems and related methods are disclosed for detecting in-pipe leaks while fluid is actively flowing through the pipe. The system can include a sensing element coupled to a membrane that are disposed parallel to or in-line with an axial direction of a fluid flow. The membrane is configured to be drawn into contact with the inner wall in response to a suction force caused bya leak. The leak is detected based on a transient output from the sensing element indicative of a stretch or strain on the membrane. The sensing element and the membrane is coupled to a support structure configured to position the membrane adjacent to an inner wall of a pipe. The support structure can include a mechanism that couples the membrane and the sensing element to the support structure and is configured to help in discriminating between leaks and false detections. 公开了管道内泄漏检测系统和相关方法，用于在流体活动地流过管道时检测管道内泄漏。该系统可包括耦接到膜的传感元件，其平行于流体流的轴向方向设置或与流体流的轴向方向一致地设置。膜被配置为响应于由泄漏引起的吸力而被拉伸以与内壁接触。基于来自传感元件的瞬时输出检测泄漏，该瞬时输出指示膜上的拉伸或应变。
