Adjustable flow divider for mass flowmeters

摘要

An adjustable flow divider for a mass flowmeter useful in shunting a portion of a fluid flow from a main supply line. The adjustable flow divider includes a porous tube (32) having a plurality of longitudinally extending projections (34) on the inner surface thereof. An externally threaded screw plug (36) is adjustably positioned within the porous tube forming a seal with the projections and exposing to fluid flow an area of porous material related to the position of the plug within the tube. The plug's position is adjustable from the outlet end of the flow divider while the divider is in use.
