摘要： Devices, systems and methods for leak detection are provided herein. Also provided are devices, systems and methods for monitoring and/or measuring fluid usage. In some aspects, a system comprising a sensor, a processing system, and a platform are provided. In some aspects, the sensor may be coupled to a spinning device. The sensor can be configured to detect fluid data, which can comprise, for example, displacement data of liquid and/or movement data associated with the liquid in a container and/or flow data associated with a flow of fluid in a conduit. The processing system can be coupled with the sensor and configured to communicate the fluid data. The platform can comprise an application communicatively coupled to one or more databases storing evaluation data (e.g., known pattern data) and configured to receive the fluid data and determine if there is a leak.

摘要： A flow detection device comprises a fluidic input port connected to a fluidic output port via a channel and a float located within the channel. A specific weight of the float exceeds a specific weight of a fluid injected in the flow detection device. Respective locations of the fluidic input port, of the channel and of the fluidic output port on the flow detection device cause the float to rise within the channel when a sufficient flow of the fluid is injected in the flow detection device. A sensor is provided to detect a position of the float within the channel. The flow detection device may be integrated in a cooling circuit having a cooling device for an electronic device to detect an eventual lack of a flow of a cooling fluid in the cooling circuit. A status of the flow of the cooling fluid is reported to a processor.

摘要： A method measures surface velocity of a fluid having a free surface flowing through a pipe or a channel. A microwave beam is sent by patch antenna including an emitting patch area and receiving patch areas parallel to the emitting patch area. Microwave signals reflected by the moving fluid free surface are received on the receiving patch areas separated by a predetermined distance. The patch antennae are either in horizontal or vertical planes parallel to the average fluid velocity. For each microwave signal received, a phase shift between microwave signals received by different patch areas is determined to calculate azimuth angles and azimuth position of reflectors on the fluid surface or to calculate the elevation angle corresponding to each signal received. Based on Doppler frequency shifts between the sent and received microwaves and corresponding phase shifts, lateral and/or longitudinal distribution of the surface velocity of the fluid is calculated.

摘要： A non-invasive microwave measuring device (01) is for calculating the flow rate of a fluid. The device (01) includes a non-invasive microwave fluid velocity measuring device (03) having a patch antenna or horn antenna to generate a microwave signal (14) that is transmitted at a specific elevation angle α towards the fluid surface (16) and to receive the reflected microwave signal (15) from the fluid surface (16) with a doppler shift frequency. The measuring device (03) is suspended from a drone (02) by a suspension system (04). The suspension system (04) eliminates vibration noise generated by the drone (02). At least one vibration sensor eliminates false velocity readings. At least one angle sensor compensates for Pitch, Roll and Yaw from the drone (02) that influence the fluid surface velocity measurement.

摘要： A system for automatic monitoring of smelt flow exiting a recovery boiler based on optical information. A processor is used to read at least one stationarily imaged video sequence, comprising digital image frames, including an area under examination representing at least part of the smelt flow exiting the recovery boiler. The processor is used to identify, in the area under examination, an area distinguishable based on colour and/or intensity information. The processor is used to determine, based on the identified distinguishable area, a monitored flow property of the smelt flow.

摘要： A catalyst alarm system for resin/catalyst spray applications, the system having a first flow sensor that monitors whether a catalyst from a manifold is flowing for supply to a spay gun or other applicator at a specified minimum rate; a second flow sensor that detects if the catalyst is flowing out of a bypass conduit of the manifold, which indicates the catalyst is not being mixed with the resin; a third flow sensor that detects if the catalyst is flowing out of an over-pressure conduit of the manifold, which indicates that only a partial amount of the required catalyst is being mixed with the resin; and monitoring circuitry for providing alarm and/or control features based on activation combinations of the three flow sensors.

摘要： Disclosed is an optical fiber flow velocity measuring apparatus and method integrating high and low ranges. The apparatus includes an integrated optical fiber flow velocity sensor, the integrated optical fiber flow velocity sensor includes a sensor body; a fluid channel, a fluid through hole, a full-pressure channel, a static-pressure channel, a low-pressure chamber and a high-pressure chamber are provided inside the sensor body; a first optical fiber sensing element is provided between the low-pressure chamber and the high-pressure chamber; a second optical fiber sensing element is provided in the fluid through hole and is perpendicular to a flow direction of a fluid to be measured; the first optical fiber sensing element and the second optical fiber sensing element are sequentially connected in series through a single-mode optical fiber; both ends of the single-mode optical fiber are connected into a wavelength division multiplexer; a pump light source is connected with the wavelength division multiplexer through a common optical fiber; an optical fiber grating demodulator is connected with the wavelength division multiplexer through a common optical fiber; and a flow velocity arithmetic unit is electrically connected with a optical fiber grating demodulator. It's an object of the present disclosure to solve the problems that the electric circuit is too complicated and that it is not easy to integrate in one apparatus when flow velocity conversion devices based on different principles are integrated.
