wherein the outer tubular probe tip has an outer opening; a connection head having an outer tube attached to a proximal end of an outer tube mid-section; wherein the outer tubular probe tip, the outer tube mid-section, and the outer tube are of a first inner diameter; wherein the outer opening of the outer tubular probe tip receives a flow of the fluid from within the pipeline that travels through the outer probe tip, the outer tube mid-section, the outer tube and connection head into the sample transport line or slipstream; a return tube, having an outer diameter smaller than the first inner diameter, disposed through the center of each of the outer tubular probe tip, the outer tube mid-section, the outer tube and the connection head; a first connection fitting for connecting return tubing to connection head; and a second connection fitting for connecting return tubing to the sample transport line or slipstream. ## Claims ### Claim 1 A probe assembly for providing a flow of a fluid from a pipeline into a sample transport line or slipstream, comprising: an outer tubular probe tip attached to a distal end of an outer tube mid-section; wherein the outer tubular probe tip has an outer opening; a connection head having an outer tube attached to a proximal end of the outer tube mid-section; wherein the outer tubular probe tip, the outer tube mid-section, and the outer tube are of a first inner diameter; wherein the outer opening of the outer tubular probe tip receives a flow of the fluid from within the pipeline that travels through the outer probe tip, the outer tube mid-section, and the connection head having the outer tube into the sample transport line or slipstream; a return tube, having an outer diameter smaller than the first inner diameter, disposed through the center of each of the outer tubular probe tip, the outer tube mid-section, and the connection head having the outer tube; a first connection fitting for connecting the return tube to connection head; and a second connection fitting for connecting the return tube to the sample transport line or slipstream. ### Claim 2 (depends on 1) The probe assembly of claim 1, wherein the outer opening has a chamfered or beveled circumference to introduce isokinetic flow through the outer tubular probe tip. ### Claim 3 (depends on 1) The probe assembly of claim 1, wherein the outer opening has a chamfered or beveled circumference to introduce isokinetic flow through the outer tubular probe tip, the outer tube mid-section and the outer tube. ### Claim 4 (depends on 1) The probe assembly of claim 1, wherein the connection head is made by machining. ### Claim 5 (depends on 1) The probe assembly of claim 1, wherein upon installation on pipeline, the outer tubular probe tip is located at or near the center of an inner diameter of the pipeline. ### Claim 6 (depends on 1) The probe assembly of claim 1, wherein upon installation on pipeline, the outer tubular probe tip is located at or near the center of an inner diameter of the pipeline with outer opening facing upstream with respect to a direction of fluid flow within the pipeline. ### Claim 7 (depends on 1) The probe assembly of claim 1, wherein the outer tube of connection head is welded to the proximal end of outer tube mid-section; and the outer tubular probe tip is welded to a distal end of the outer tube mid-section. ### Claim 8 (depends on 1) The probe assembly of claim 1, wherein the first inner diameter is about 1.5 inches and the return tube has an inner diameter of about 0.75 inches. ### Claim 9 (depends on 1) The probe assembly of claim 1, wherein the first inner diameter is about 1 inch and the return tube has an inner diameter of about 0.5 inches. ### Claim 10 (depends on 1) The probe assembly of claim 1, wherein the first inner diameter is about 0.75 inches and the return tube has an inner diameter of about 0.5 inches. ### Claim 11 (depends on 1) The probe assembly of claim 1, wherein the connection head is attached to the pipeline by a threaded or flanged connector. ### Claim 12 (depends on 1) The probe assembly of claim 1, wherein the return tube has a return opening facing downstream with respect to a direction of fluid flow within the pipeline. ### Claim 13 (depends on 1) The probe assembly of claim 1, wherein the outer opening of probe tip has a radius at the top and bottom and is generally ellipse-shaped. ### Claim 14 (depends on 1) The probe assembly of claim 1, wherein the outer opening is sized as follows: 1.5″ Outer Tubing inside diameter: the outer opening is about 1.232″ wide×1.607″ long; 1″ Outer Tubing inside diameter: the outer opening is about 0.870″ wide×1.120″ long; or ¾″ Outer Tubing inside diameter: the outer opening is about 0.625″ wide×0.875″ long. ### Claim 15 (depends on 12) The probe assembly of claim 12, wherein the return opening is ellipse-shaped and sized as follows: ¾″ Inner Tubing inside diameter: the return opening is about 0.602″ wide×0.891″ long; ½″ Inner Tubing inside diameter: the return opening is about 0.402″ wide×0.574″ long; or ⅜″ Inner Tubing inside diameter: the return opening is about 0.277″ wide×0.396″ long.
