PCT No. PCT/IE97/00011 Sec. 371 Date Aug. 19, 1998 Sec. 102(e) Date Aug. 19, 1998 PCT Filed Feb. 21, 1997 PCT Pub. No. WO97/30930 PCT Pub. Date Aug. 28, 1997An apparatus for adding an additive, such as a marker, to a base fluid, such as oil, includes a blender having a receptacle or diffusion chamber in which mixing of the additive and the base fluid occurs. The additive is injected in discrete amounts. Resistances to fluid flow in the receptacle or chamber cause fluid flow to occur at different rates in order to reduce the slugging effect caused by additive injection in discrete amounts. |
