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.
Claims18
A spot sampling system for use with a source of hydrocarbon product, said system comprising an inlet;
- an outlet in fluid communication with said inlet along tubing;
- a servo-electric controlled actuator coupled along said tubing;
- a control valve along said tubing, said control valve operable to isolate said actuator from said inlet and outlet, thereby forming two distinct tubing sections;
- and a can at a terminal in fluid communication with said actuator.
A method of sampling a flow of petroleum-based liquid in fast loop process comprising the steps of:
- a. connecting an inflow to extract flowing petroleum-based liquid into a sampling;
- system;
- b. providing an outflow for petroleum-based fluid to exit the sampling system;
- c. allowing petroleum-based fluid to enter through the inlet and flow past an actuator;
- d. closing a control valve thereby bypassing the actuator;
- e. discharging petroleum-based fluid from the actuator into a receiving container;
- and
- f. opening the control valve to reconnect actuator to the petroleum-based fluid flow from inlet.
