A multi-phase sampling collection system includes a three-way four-port valve unit that includes a valve housing having a first port, a second port opposite the first port, and a third port. The valve unit includes an inner valve member that is movably disposed within the valve housing between a plurality of positions. The inner valve member has a main valve body that has a first valve opening, a second valve opening opposite the first valve opening, a third valve opening and a fourth valve opening opposite the third valve opening. The third valve opening is defined by a plurality of orifices for mixing incoming non-homogenous fluid to generate a mixed homogenous fluid and the fourth valve opening has a lesser diameter that the third valve opening for increasing fluid pressure drop, fluid velocity, and fluid turbulence resulting in improved mixing of the non-homogenous fluid that exits through the fourth valve opening.

A technique facilitates evaluation of a fluid, such as a fluid produced from a well. The technique utilizes a modular and mobile system for testing flows of fluid which may comprise mixtures of constituents, and for sampling fluids thereof. The multiphase sampling method includes flowing a multiphase fluid comprising an oil phase and a water phase through a first conduit, the oil phase and water phase at least partially separating in the first conduit, mixing together the oil phase and water phase to form a mixed bulk liquid phase by flowing the multiphase fluid through a flow mixer toward a second conduit downstream the flow mixer, sampling a portion of the mixed bulk liquid phase at location at or within the second conduit, wherein the sampled portion of the mixed bulk liquid phase has a water-to-liquid ratio (WLR) representative of the pre-mixed oil phase and water phase.

Example aspects of a pit assembly, a fluid testing system, and a method for using a fluid testing system are disclosed. The pit assembly can comprise a pit housing; a curb stop assembly comprising a curb stop valve, the curb stop valve mounted within the pit housing; and a pressure transducer mounted within the pit housing.

Systems and methods are described for isolating a sample at a valve prior to introduction to an analysis system, such as sample analysis via ICP-MS. A system embodiment can include, but is not limited to, a valve system including a first valve in fluid communication with a sample reservoir and a second valve configured to permit and block access of a vacuum source to the first valve; a sensor system configured to detect presence or absence of a fluid at the first valve; and a controller configured to control operation of the second valve to block access of the vacuum source to the first valve upon detection of the fluid at the first valve to isolate the fluid within the sample reservoir.

An irrigation management system is disclosed and positionable in-line with an irrigation pipe for monitoring and controlling a flow of fluid therethrough. In at least one embodiment, the system provides an inlet pipe and an opposing outlet pipe in serial fluid communication with the irrigation pipe. At least one fluid control valve is in serial fluid communication between the inlet pipe and outlet pipe for selectively controlling the flow of fluid therebetween. The fluid control valve provides a main valve and a hydraulic actuator for selectively moving the main valve between open and closed positions. The hydraulic actuator is also in serial fluid communication between a pair of actuator valves for moving the hydraulic actuator between open and closed positions. The system also provides at least one sample collection tank configured for temporarily storing a volume of fluid diverted from the irrigation pipe in order to be tested.

A vortex suppression device (10) for a fluid flowing along a pathway (A-E), including: an elongate body with an outer surface having an elongate leading section and an elongate trailing section along the length of the elongate body, in relation to a direction of fluid flow (A-E) when the device is located in the pathway, the elongate body having at least one channel (24a-24d, 26a, 26b) which extends from the elongate leading section to the elongate trailing section of the elongate body, the channel (24a-24d, 26a, 26b) being configured so that in use, when the device is in the pathway, the channel (24a-24d, 26a, 26b) allows fluid flow (J) towards the trailing section that disrupts the formation of vortices (D).

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.

A method of analysing granular material in a slurry, the method comprising: compacting the granular material in the slurry to form one or more pucks; irradiating said pucks with X-Ray radiation and detecting X-ray energy transmitted through said one or more irradiated pucks; irradiating a reference material with X-Ray radiation, said reference material having known material characteristics and detecting X-ray energy transmitted through said reference material; comparing X-ray energy transmission through said one or more pucks with the reference material to compute, using a processing unit, one or more particle characteristics of the granular material in the one or more pucks.

A liquid quality measurement apparatus includes a piping constituting a circulation path through which a measurement liquid flows, and a liquid quality sensor for measuring the quality of the measurement liquid, and an addition tank connected to the piping via an inlet port and an outlet port. The addition tank has an internal space, an introduction portion through which a liquid different from the measurement liquid is introduced, and a ventilation portion through which air is released from the internal space to the outside. An addition tank internal channel is formed at a bottom portion of the internal space. The addition tank internal channel connects the inlet port and the outlet port. The measurement liquid flows through the addition tank internal channel. The introduction portion and the ventilation portion are disposed in a wall surface of the addition tank that faces the internal space above the addition tank internal channel.

An analytical toilet comprising a bowl for receiving excreta from a user; a base supporting the bowl; a supply of flush water; and a plurality of receptacles, each providing mechanical attachment, a power supply, and a data connection to an analytical device, which analytical device is adapted to provide data useful to the user is disclosed.
