ABSTRACT:
A crude oil sampling apparatus having a purge system as set forth in the preferred and illustrated embodiment. The sampling system includes an elongate probe which is driven by a diaphragm motor. This probe extends through a fixed housing and terminates at a sample collection head. The probe is provided with two passages through it. One passage is to remove the sample. As the probe is reciprocated, it captures sample and the sample is forced into the probe and along a passage therein past a check valve. The system includes a second passage opening into the first passage through a check valve. This is included to purge the probe and thereby empty or void the passage whereby all vestiges of a sample can be delivered from the equipment into a collection container or the like.
