ABSTRACT:
A system and method of obtaining an accurate sample of a fluid in a container comprising providing a container for accommodating a fluid to be analyzed, providing a hollow vessel of predetermined varying internal volume dimensions from one end of the vessel to the opposing end of the vessel disposed within the container, permitting and then stopping fluid flow from the container into the vessel and removing fluid from the vessel for analysis. The axis of the hollow vessel is positioned vertically and the hollow vessel is provided with a plurality of vertically spaced apart apertures controlled by the valve for receiving the fluid. The predetermined varying internal fluid receiving volume dimensions are controlled by providing an insert in said vessel having volume dimensions inversely proportional to the volume dimensions of the container at each height level in the container. The container is preferably cylindrical and has rounded ends, the vessel is circular and the insert is of conical shape and has a varying diameter D=d(h/r)[1-Z((3h.sup.2 +Z.sup.2)/3r.sup.2 L)], where d is the inside diameter of the vessel, r is the radius of the cylinder, Z is the length of the rounded ends along the center line, h is the varying reference height from the container center line at which each incremental diameter D of the volume compensating insert exists and L is the length of the cylindrical portion of the container.
