The Impeller-Type Sampler is installed as an integral part of the pipeline. No outside power or control is required. This Impeller-Type Sampler for flow-controlled sampling features an impeller-driven sampling probe and sample circulation return probe assembled to a blind flange and mounted on a tee-flanged outlet positioned inside pipeline. This system incorporates a rotary sampling valve， McFarland-Tritan， LLC sample volume regulator， inlet probe， return probe piping with shut-off valves and fluid pressure regulator. Rotary sampling valve and fluid-powered impeller control sampling frequency. Adjustable sample volume regulator， from 0 to 2.5 cubic centimeters controls sample size. Rotary sampling valve alternately connects the volume regulator to the probe for filling or to the sample container for emptying. Rotary sample valve， sample volume regulator and probe arrangement are designed to permit passage of sand and BS&W through the sampler without clogging or damage. No check valves are required- eliminating the potential for cutting or plugging. This fluid sampling system will mount on blind flange without tee or on existing pipelines by addition of a saddle， flanged outlet and hot tap. A 24-inch sampler is provided for lines above 24 inches-customer should advise dimension from center of pipeline to face of the sampler-mounting flange. The Impeller-Type Sampler can be supplied mounted on flanged side outlet of a plain end tee， beveled for welding into the pipeline. Flange size and pressure rating are matched to line requirements. Sample volume regulator capacity: 0 to 10 cubic centimeters. Special volume regulators available for large sample sizes. Accessories include sample container， sheet-metal house， companion flanges， and studs and gasket. Fluid flow provides the power and controls the sampling rate. Changes in the sampling rate are directly proportional to changes in the flow rate in the pipeline. Installed in horizontal or vertical lines in accordance with API sampling standards.
