Abstract

A sampling device for sampling fluids such as those carried in an oil pipeline comprises two valve means and a sampling chamber located on the fluid passageway in the sampler housing. Fluid is admitted to the probe of the sampling device when the first valve means allows the passageway to be opened and the fluid is admitted or drawn into the sampling chamber. After the first valve means is closed, the second valve means is opened and the fluid exits from the sampling chamber under the action of the plunger. Provision is made to easily clean the buildup of deposits in the fluid passageway without disassembly of the sampling device.
