Two probes in one, the Pitot Probe has an outlet and return. The differential pressure created across these ports results in a product circulation loop between the pipeline and the sampling equipment. Pipeline product flows through the hot loop, continually presenting fresh product to the sampler or sampling system, allowing for collection of representative samples. Depending on the properties of the sampled product and the length of tubing between the Pitot Probe and the sampling equipment, a circulation pump may be required to ensure sample representativeness.
