Abstract: A servo-electric actuated sampler can draw samples of fuel liquid from an operating main line. The sampler can run in a fast-loop process whereby liquid is drawn into the sampling system and past an actuated sampler and then out of the system back into main. The system main run a short loop whereby the main fast-flow is restricted, and the actuator and sampler are isolated from the main line flow. When isolated, the sampler discharges liquid into sampling cans. The servo-electric actuator requires a monitored amount of power to draw and discharge fluids. Monitoring of the power requirements of the servo-electric sampler can reveal the status and reliability of the system.

Abstract: A prover includes a piston supporting rod extending longitudinally through a cylinder, which cylinder receives and discharges a fluid to measure the volume and flow rate of the fluid by translation of the piston from the fluid receiving end to the fluid discharging end. Prover valve includes improved poppet valve disk shape that provides for smoother fluid flow, additional volume, and better sealing. Disk also includes angled wings and complimentary poppet seating to provide for better and more resilient seal. Retention ring may be fitted over poppet seal, and includes bolts that provide for removing retention ring to allow servicing of poppet seals (and replacement thereof) while tension remains on prover valve and rod.

Abstract: A hydrocarbon line sampler connected to a pipeline containing hydrocarbon fluid, the sampler including a draw mechanism and a sampling can. The sampler includes a detector for testing a quality attribute of the fluid. The detector passes a signal to a controller, the controller being preprogrammed with a set threshold of one or more quality thresholds. When a quality threshold is met, the controller can modify the sampling regimen for later storage or further on-site testing. The invention includes a method of drawing a sample, testing the sample, determining the quality of the sample, and modifying the sampling regimen as need, or otherwise setting an alarm, or taking action on the pipeline system.

Prover valve includes improved poppet valve disk shape that provides for smoother fluid flow, additional volume, and better scaling.

Retention ring may be fined over poppet seal, and includes bolls that provide for removing retention ring to allow servicing of poppet seals (and replacement thereof) while tension remains on prover valve and rod.
