Fluid sample apparatus featuring integral construction with a motor driven sampling system

A fluid motor integrally constructed on an elongate body enables periodic fluid sampling. This device affixes to a pipeline by a threaded connection which positions an inlet in the pipeline for sample removal; the sample flows to a sample bite removal valve which is motor operated to obtain periodic simple bits. Pressure step up or down is achieved in a sample pressure isolation system having a check valve function. This enables storage at any pressure.

Claims

3. The assembly of claim 1 wherein said elongate body is formed by:

(a) a lower end portion having a downwardly extending probe for insertion into a pipeline, and said probe extends from a threaded fitting cooperatively connecting to a mating fitting on the pipeline;
(b) an intermediate portion supporting said outlet means and said check valve means; and
(c) an upper end portion comprising said second end and supporting said motor means wherein said upper end portion is joined with and connected to said intermediate portion to align sad body portions for joinder in an integrated assembly.
