ABSTRACT:
A fluid strainer and flow corrector for use with a fluid flow measurement device, such as a turbine-type flow meter, consists of a generally conical grid of ribs attached to an annular base flange. The base flange of the strainer/flow corrector fits into a groove formed on the inlet side of the housing of the flow meter and is held in place by means of a flexible snap-ring. The strainer/flow corrector is arranged with its apex upstream of the flange portion with respect to the direction of fluid flow through the inlet of the flow meter. The spacing between the ribs is chosen as to block the flow of debris which might be present in the fluid flowing through the flow meter. The spacing between the ribs is also chosen to provide a desired velocity profile to the fluid. The strainer/flow corrector may be easily removed or replaced without disconnecting the flow meter from its associated pipework.
