Fluid Sampling Systems

Crude oil prices necessitate accurate measurement of the BS&W content in oil. Manual sampling methods can result in samples with inaccurate and inconsistent values.

Automatic Fluid Sampling Systems

• Designed to collect continuous, representative samples of oil and BS&W
• Dependable sampling permits accurate determination of the BS&W percentage

• Engineered for proportionate to flow sampling controlled by a fluid meter or other electrical impulse source
• Cost-efficient for crude oil sampling on LACT units
• Flexible installation: sample probe installed in pipeline; line can be powered from meter or timed to solenoid
• Features 0 to 2.5 cubic centimeter-capacity adjustable sample volume regulator; solenoid-operated, explosion-proof three-way sampling valve and fluid inlet pressure regulator
• Assembled on convenient mounting bracket
• Sample volume regulator for larger size samples, from 0 to 10 cubic centimeters, is available
• Supplied without pressure regulator and gauge for sampling when line pressure is below 50 pounds per square inch and relatively constant
• Three-way solenoid sampling valve can be supplied "normally closed" for sample entry during the "power-on" time of the cycle
• Solenoid valves are available for most power characteristics
• A complete line of accessories includes McFarland-Tritan, LLC sample probes, sample containers and sample houses
• Units can be modified for timer-controlled operations

• Features 1/2 horsepower, 3.5 gallon-per-minute, motor-driven pump for slip-stream circulating along with the standard Economy Sampler components
• Circulates fluid through the probe and by the solenoid sampling valve at adequate velocity to keep water and solids in suspension
• Permits the installation of the sampler remote from the pipeline
• Motors available for most requirements
• Installation similar to the Economy Sampler, but with an added return circulation line
• Provides constant-volume sampling when used with a timer
• Sampling rates are fixed for any single setting of the timer, but other rates can be obtained by manual resetting of the timer
• Can be customized for use with the Economac Sampler

• Installed as an integral part of the pipeline
• No outside power or control is required
• 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
• 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 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
• 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
• 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 gaskets
• 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
