A flow splitting device (10) for use in fluid flow meters and the like including an outer housing (12) forming a cavity having an inlet (28) and an outlet (30), a porous baffle (32) dividing the cavity into an inlet chamber (35) and an outlet chamber (37), an apertured plug (42) having one end engaging the surface of the baffle facing the outlet chamber and a tube (62) extending through the housing and into communication with the plug, and an opposite end (60) extending through the housing and into communication with the outlet chamber. The external portion of the tube (62) being suitable for coupling with a sensing device for measuring the split flow therethrough.

In a flow meter of the type having splitter means for splitting off a sample of a fluid flow stream to be monitored, sensing means for sensing the flow of fluid in the split stream, and means for indicating the output of the sensing means, an improved splitter means comprising: housing means forming an internal cavity having an inlet and an outlet; porous baffle means disposed within said cavity so as to divide said cavity into a first chamber communicating with said inlet and a second chamber communicating with said outlet; plug means disposed at least partially within said second chamber and engaging a wall of said baffle means, said plug means having an opening therein forming a passageway for fluid passing through a predetermined area of said porous baffle means defined by said opening; sensing tube means having one end communicating with said plug means to receive fluids passing through said passageway, and an opposite end communicating with said second chamber, whereby fluids flowing into said inlet pass into said first chamber, through said baffle means into said second chamber, and thence out through said outlet with a predetermined portion of the fluid flowing through said baffle means passing through said tube means prior to passing into said second chamber.
