Abstract: A flow measuring system detects fluid flow in a subsea well. A disclosed flow measuring system may comprise a housing 12 attached over a hole 22 or riser aperture, defined within a riser 20, creating a fluid pathway. Continuous louvers 27 may span the riser aperture, filtering the flow of fluid reaching the fluid pathway. The direction and volume of flow within the fluid pathway may be measured by sensors attached to the housing. In an alternative embodiment, director plates 29 may be integrated with or integral to the louvers with the director plates influencing the flow of fluid to, within and out of the fluid pathway. The use of flow measurement sensors within the fluid pathway is also disclosed. In one embodiment, no louvers or director plates are used, thus increasing the fluid communication between the riser and housing.

Abstract: A flow measuring system is adapted to measure flow in a sub-sea well. The flow measuring system has a housing, attached over a hole in a riser creating a fluid pathway therebetween. A deflector plate is attached to the riser and covering some of the hole. Upper vertical louvers and lower vertical louvers directly attached to the deflector plate over the hole. Apertures in the upper vertical louvers and the lower vertical louvers permit fluid to flow through. A flow measurement device is mechanically coupled to the housing and the deflector plate and configured to determine a speed and direction of flow through the fluid pathway.
