摘要：
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.
