The present disclosure is for a tool for measurement of phases in fluid in downhole applications. The tool includes a light coupler for providing a first light and for detecting a second light. The first light is provided to an optical interface and the second light is received from the optical interface. The optical interface is between the tool and the fluid. An optical path is provided that is integral or coupled to the optical interface. The optical path allows transmission of the first light into the fluid at the optical interface and also allows receiving the second light from the optical interface. The second light includes one or more light components disturbed by the fluid. A processor provides digital data associated with the measurement of phases in the fluid using optical data from at least the second light.

In the additive manufacturing process, a monitored or controlled mixture of materials is deposited to form an additive manufactured product by delivering the mixture of materials through a material flow path while using an excitation source to introduce electromagnetic energy into the material flow path using a circuit element having inductive or capacitive reactance disposed adjacent the material ejecting orifice. The excitation source produces an electromagnetic field condition within the material flow path that is responsive to at least one of the permeability and permittivity properties of a space within the material flow path. A sensing means coupled electrically or magnetically to the excitation means is responsive to the electromagnetic field condition and provides at least one control parameter based on the electromagnetic field condition that may be used to control the composition of the mixture of materials by adjusting proportions of constituent materials.

A condensation irradiation system is disclosed comprising an electromagnetic radiation emitter mounted on a locating structure, the locating structure being arranged in use to position the radiation emitter so as radiation emitted therefrom travels through a condensation detection region adjacent an upstream side of a gas turbine engine fan.

The present invention refers to an online monitoring system for the gravitational separation of oil emulsions, more specifically, a monitoring system for the properties related to the emulsions, such as the drop size distribution (DSD) and the water content (WC), simultaneously, in pressurized and heated systems at high pressures and temperatures, respectively, using near-infrared region (NIR) spectroscopy coupled with optical microscopy.

The online monitoring system is innovative as it overcomes the current need of the oil industry to remove aliquots from emulsified systems under high pressure and temperature, preferably up to 70 bar (7 MPa) and 150? C., respectively, for determination of the properties of emulsions, which causes disturbances and affects the physicochemical characteristics of emulsions. Thus, the invention makes it possible to infer about the stability of the emulsions under real operating conditions by monitoring the gravitational settling of water drops dispersed in a continuous phase of oil.

A filter-press filter-cloth damage detection device for a filter press includes a detection path and a detection device. In the filter press, a filtrate produced by solid-liquid separation operation of a filter cloth nipped between filter plates is discharged into a collection pipe via a filtrate passage of each of the filter plates. The detection path extends in a straight line. A filtrate discharged from each of filtration chambers formed between adjacent filter plates is collected to the detection path. The detection device is configured to transmit, from an end portion of the detection path, an irradiation wave or a pulse that reflects on an interface between a clear filtrate and a filtrate with a prescribed turbidity, convert a propagation time from the transmission until reception of a reflected wave into a distance, and output the distance.

The present invention relates to determining phase information of a fluid sample. At least one image of the fluid sample including the phase information of the fluid sample is provided. Additionally, a data driven model which comprises at least one output channel for the phase information is provided. The at least one output channel includes at least one output channel for classifying a boundary between two phases of the fluid sample, such that the phase information includes information about a property of the boundary between the two phases, such as a height, a volume, a type, or a strength of the boundary. The phase information of the fluid sample is derived based on the data driven model and the at least one image of the fluid sample including the phase information of the fluid sample.
