Abstract
To obtain two or more fluid samples simultaneously, a sampling probe is provided which has an outer tube coaxially disposed about an inner tube. The ends of the inner tube and outer tube are typically spaced apart longitudinally, so that they may be positioned at different locations within a pipeline. Fluid flows through the inner tube and through the annulus formed between the inner tube and the outer tube. The fluid is then withdrawn from the inner tube and from the annulus for testing.
