A particle characterization apparatus and corresponding method is disclosed. The apparatus comprises a sample cell (14). The sample cell includes: an input opening (26) for receiving a fluid that carries particles flowing along a flow axis, a central acquisition channel (32) hydraulically responsive to the input opening (26) for receiving a first subset of the fluid, a pair of lateral bypass channels (32, 34) hydraulically responsive to the input opening (26) and disposed on either side of the central acquisition channel (32) for receiving second and third subsets of the fluid, a window (36) in the central acquisition channel (32) for illuminating the first subset of the fluid in the central acquisition channel (32),an illumination source (18) positioned to illuminate the fluid in the central acquisition channel (32) through the window (36), and a detector (20) positioned to receive light from the fluid in the central acquisition channel (32) after it has interacted with the fluid.

Described herein is an in-line sensor for sensing properties of a pulsed milk flow on a continuous basis. A milking cluster comprising multiple pulsed milk flow inputs from lactating animal teats and a mixing point or claw for the multiple inputs is described that includes multiple in-line sensors for each pulsed milk flow input. Methods of use of the in-line sensor and milking cluster are also described. The in-line sensor described may be easily integrated into existing milking apparatus, is reliable, has a low cost, and is self-cleaning/self-emptying.

A pipeline insertion device is disclosed which is suitable for in-line flow rate measurement of a fluid in a pipeline, and which comprises an elongate device body having an outer surface comprising an in-use upstream portion and an in-use downstream portion. There is also a plurality of fluid-flow-directing elements positioned on the outer surface of the elongate device body, the plurality of fluid-flow-directing elements being perimetrically offset to both the upstream portion and the downstream portion of the elongate device body.

A removable apparatus having a core holder body and a core sample assembly fitted inside the core holder body is disclosed. The core sample assembly includes a core sample and a sleeve fitted around the core sample. A first flanged stopper and a second flanged stopper are positioned at opposite axial ends of the core holder body. A flow path is formed through the first and second flanged stoppers and interfaces at opposite end surfaces of the core sample. Also provided are an assembly and a system comprising the removable apparatus for use in oilfield applications. Further, a method of testing a property of a fluid using the removable apparatus is provided.

Described herein is an in-line sensor for sensing properties of a pulsed milk flow on a continuous basis. A milking cluster comprising multiple pulsed milk flow inputs from lactating animal teats and a mixing point or claw for the multiple inputs is described that includes multiple in-line sensors for each pulsed milk flow input. Methods of use of the in-line sensor and milking cluster are also described. The in-line sensor described may be easily integrated into existing milking apparatus, is reliable, has a low cost, and is self-cleaning/self-emptying.

A sampling system measures an analyte of interest present in a system of interest, wherein the analyte of interest is included in a medium, e.g., a fluid or another viscoelastic material. The sampling system includes a three-way junction, an inlet channel, an outlet channel, a measurement channel and a measurement chamber. A multiplexed sampling system includes two or more sampling systems. A method for measuring an analyte of interest present in a medium includes using the sample system.

An automatic sampling device (autosampler) is provided for continuous water sample collection and visual inspection for the presence of particulate solids in water sources. The autosampler is capable of collecting larger water samples, over a longer period of time, than typical inline monitoring and sampling methods. This provides more accurate information regarding the presence and concentration of particulate solids in the water sample as compared to most inline methods. More particularly, the autosampler includes a plurality of plastic pellet and powder capture nets (P3CNs), each of which is designed with nested nets for catching and retaining particulate solids of sequentially diminishing particle size along the flow path of the water sample. This enables easy determination of the presence of particulate solids, as well as a quick assessment of the different sizes of particulate solids present in the water samples by visual inspection of the P3CNs.
