Abstract: A leak monitoring manifold is provided to detect and regulate sample leaks in a pump system. The manifold may include a fluid inflow location and a relief valve including a relief outlet which is in fluid communication with the fluid inflow location. The relief valve may operate to be in either of a first state or a second state. In the first state fluid flow out of the relief outlet is blocked, and in the second state fluid flow is open between the fluid inflow location and the relief outlet. The relief valve may alternate between the first state and the second state when a pressure acting on the relief valve reaches a preconfigured pressure set point.

Abstract: A system is provided for testing and sampling of crude oil that includes a crude oil sampler system with a circulation loop and a water cut meter incorporated into the circulation loop. The system provides for a water cut meter positioned downstream of a sample withdrawal point. As the sample of crude oil passes through the circulation loop, the water cut meter can be used to determine the percentage of water cut of the sample. After passing through the circulation loop and determination of the water cut, a secondary sub-sample of the crude oil may be drawn off from a draw-off valve. The secondary sub-sample may then be sent to a laboratory or testing center for further testing or verification of the initial water cut.

Abstract: A sample pressure reducing system is provided that integrates various pressure applications into a single system that provides the end user with a high-integrity sample without damaging equipment. The system facilitates sampling high-pressure product into a low-pressure container. The system fills and transfers product to reduce pressure automatically and repeatedly.

Abstract: A gasoline blend spot sampling system and method including an adjustable volume mechanism for retaining an adjustable volume of gasoline for sampling, a coolant system integrated with the adjustable volume mechanism, and a sample collection assembly using a blunt-end tube for use with an open-mouthed bottle. Various three-way valves are actuated to route gasoline through various stages of a sampling process, from a gasoline fast loop to a purge loop to a gasoline capture stage to a sample bottling stage.

Abstract: In combination, a liquid sample pump and an integral self-cleaning filter element will elongate the maintenance interval for the pump which saves on time and labor costs. The filter element itself is small, economical to make and forms an integral part of the liquid sample pump. A flow passageway continuously directs turbulent liquid to the underside of the filter element to sweep debris from the filter element and return such debris to the pipeline. When it is necessary to service the liquid sample pump, it is quick and easy to remove and replace the filter element, which also saves on time and labor costs. A bleed valve assembly allows air to be bled from the sample pump prior to operation, enhancing seal life. An optional muffler assembly excludes insects from the inside of the sample pump, again elongating maintenance intervals. An optional return valve assembly allows unused sample to be returned to the pipeline, thus benefitting the environment.
