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 sample bits. Pressure step up or down is achieved in a sample pressue isolation system having a check valve function. This enables storage at any pressure.

An assembly for obtaining a fluid sample from a pressurized pipeline comprising: (a) an elongate body having (i) a first end formed to connect to a pipeline to position a pressurized fluid inlet in the pipeline to receive pressurized fluid; (ii) a central body portion connected to said first end; and (iii) a second end deployed from said first end; (b) a fluid flow line connected from said fluid inlet to deliver a flow of fluid; (c) fluid sampling means connected to said fluid flow line to deliver fluid thereto in a volume in excess of said sample; (d) said sampling means periodically removing fluid from said fluid flow line; (e) outlet means connected to said sampling means for delivery of a fluid sample without regard to the pressure in the pipeline; (f) check valve means cooperative with said outlet means to enable fluid to flow through said outlet means to overcome back pressure encountered by fluid flow; (g) rigid chamber connecting means connecting said sample means and check valve means; and (h) motor means in said body for operating said sampling means to direct fluid through said outlet means.
