Abstract
Abstract A self-powered sample probe for providing a continuous flow of fluid to an analyzer is located with the fluid stream to be analyzed. The probe has an inlet facing upstream and return openings facing approximately ninety degrees on either side of the upstream inlet. The differential pressure head between the inlet and return openings is sufficient to provide continuous flow through the sample loop and external analyzer and to return the fluid back into the main stream.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
123 words
Means for continuously analyzing a flowing fluid comprising: a. a probe for sampling said flowing fluid having: 1. an entrance facing upstream into the direction of the flow of the fluid; 2. a first passageway connected to said entrance; 3. an exit located at about plus or minus ninety degrees relative to said entrance, thereby achieving the maximum pressure differential between said inlet and said outlet; 4. a second passageway connected to said exit; b. analyzer means operably communicating with said sample probe whereby a portion of said flowing fluid may be analyzed, said analyzer means being operably connected to said first and second passageways in said probe, said analyzer means being operative only when the maximum pressure differential of (a) is available.
Claim 2
Dependent Claim
