摘要： A vortex flowmeter includes a housing having an interior cavity, a vortex shedder supported by the housing and extending into the interior cavity, an ultrasonic sensor, a bending moment sensor and a controller. The ultrasonic sensor is configured to produce an ultrasonic flow rate output that is indicative of the flow rate of a fluid flow through the interior cavity. The bending moment sensor is configured to produce a bending moment flow rate output that is indicative of the flow rate of the fluid flow through the interior cavity. The controller is configured to generate a flow rate measurement that is indicative of the flow rate based on the ultrasonic flow rate output and/or the bending moment flow rate output.

摘要： A method is provided to measure a distribution of axial velocities and a flowrate in a pipe or a vessel. The method comprises selecting a single cross-section at a stable-flow segment in a pipe or a vessel, installing a plurality of acoustic wave sensors along a peripheral wall of the pipe or the vessel to form a plurality of effective sound wave paths; measuring sound wave travelling time on each sound wave path; substituting the measured sound wave travelling time data into the model formulas based on a sound path refraction principle for reconstruction calculation to obtain a distribution of axial velocity in the measured cross-section of the pipe or the vessel, u(x,y); and integrating the distribution of the axial velocity u(x,y) along the cross-section to obtain a flow rate. A system is also provided to measure an axial velocity distribution and a flow rate in a pipe.

摘要： An apparatus for testing of downhole multiphase fluid handling systems used in oil and gas production allows test personnel to visually observe the testing. The apparatus is constructed from housings and/or casings made partly or entirely of a see-through material. The see-through material allows for unaided visual observation of the flow regime of the fluid flowing through fluid handling equipment. This eliminates most all of the assumptions that typically need to be made about how well the equipment operates. The ability to clearly observe the flow regimes unassisted allows for accurate study of individual equipment effects, vortices interactions and formation, the effects of different velocities of fluid flow, the optimization of flow paths, remixing and flow regimes external of a system, slug creation, and other parameters known to those skilled in the art.

摘要： A system is provided for tracking, in a distributed water infrastructure, water usage by category. The system may comprise at least one processor configured to receive from at least one sensor associated with the distributed water infrastructure signals indicative of water usage in the distributed water infrastructure. The system may, based on the signals indicative of water usage, construct a plurality of profiles. The system may assign each profile to one of a plurality of water usage categories. The system may collect, from the at least one sensor, signals indicative of water usage for substantially all water delivered through the distributed water infrastructure in a time period. The system may construct a plurality of water usage profiles in the aggregate, encompassing substantially all water delivered through the distributed water infrastructure in the time period. The system may assign each constructed water usage profile to one of the plurality of water usage categories. The system may output, for display, water usage for the time period for each of the plurality of water usage categories.

摘要： A computer-implemented method for visualizing uncertainty in flow measurements is provided. A non-limiting exemplary method includes reading, by a processor, a plurality of fluid flow measurements having a magnitude, a direction, and a location. The method plots a plurality of points on a first polar graph, each point representing the difference in fluid flow measurements between two of the plurality of fluid flow measurements at different locations and calculates an uncertainty boundary line based on the plurality of plotted points. The method filters, by the processor, the plurality of plotted points to remove plotted points outside of the uncertainty boundary line leaving only remaining plotted points and defines at least one cluster of remaining plotted points based on similar behavior of a subset of the remaining plotted points. The method may use the remaining plotted points to provide adaptive setup to tune a response in the fluid flow measurements.

摘要： A gas meter having a sensor module and at least one bypass module is described herein. In an example of the gas meter, an enclosure defines an interior cavity within which a manifold may be configured to include a sensor module connector, at least one bypass module connector, and an exhaust port. A sensor module may be connected to the sensor module connector of the manifold and may measure a flowrate through the sensor module and into the manifold. A bypass module may be connected to the bypass module connector of the manifold to bypass gas around the sensor module. A processor may be used to compute a gas flowrate through the meter using inputs including the measured flowrate and data based on the measured flowrate to adjust for gas that bypassed the sensor module.

摘要： The invention relates to a compound water meter, consisting of a main meter, connectable to a main line, for detecting larger flow rates, and an auxiliary meter, arranged in an annular channel, for detecting smaller flow rates, wherein the measuring insert of the main meter is assigned a switching valve connected with it and opening the passage through the main line upon achieving a certain differential pressure against the action of a spring element.
In order to create an improved compound water meter, it is suggested within the scope of the invention that the spring element is arranged in the interior of the switching valve and a single seal of the switching valve is axially arranged on the non-moveable part.
Through the arrangement of the spring element in the interior of the switching valve, the switching valve is only sealed via a seal. Through the axial arrangement of the seal, in contrast to the prior art, in which the one radial seal is provided, it is achieved that the sealing point is particularly low-wear. In contrast to the prior art, only one seal is provided in the compound water meter according to the invention, which entails a simplification of the manufacturing process, as well as also an increase of the operational safety.
