A wellbore leakage detection tool and method for assembling such tool includes a longitudinal tool element, including a through bore perpendicular to a longitudinal axis of the longitudinal tool element, an acoustic insulator or damper arranged in the through bore, and an acoustic sensor assembly arranged suspended in the acoustic insulator or damper inside the through bore. The acoustic insulator or damper has an acoustic impedance different from an acoustic impedance of the tool element.

Wellbore leakage detection tool and method for assembling such tool

This invention relates to a device for mounting in a fixed mounted frame () on a subsea pipe comprising a locking device comprising a sensor housing (), a spring () surrounding the sensor housing (), at least one wedge () placed in one of the ends of the spring (), and a edge () placed in the other end of the spring (), where the sensor housing () is arranged to be guided into the mounting frame (), and that a force () is applied in the longitudinal axis of the sensor housing () so that the spring () is compressed and the wedge(s) () are spanned radial out towards the mounting frame () to center and support the sensor housing () in the mounting frame (), the sensor housing () is designed to fit into the mounting frame ().

Locking mechanism with acoustic barrier for mounting a sensor on a pipe

This invention relates to a system for measuring solid particles, e.g. sand, in a fluid flow in a pipe, comprising at least one acoustic sensor for registering acoustic signals generated from collisions between particles and a surface. The pipe comprises a constriction through which the fluid flow passes, and that at least one of said acoustic sensors are positioned in relation to said constriction, and on a surface facing toward the flow so as to receive acoustic signals resulting from collisions between particles and the surface.
