    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 herein are apparatuses and methods related to open channel flow measurement of process fluids. In certain embodiments the apparatus has a collection trough to receive the process fluid from a unit process, baffles to slow the flow of the process fluid to subcritical flow, and a measurement channel. A level measuring system is connected to the measurement channel and can determine the height of the process fluid in the measurement channel. The flow of the process fluid can be inferring using the height of the process fluid in the measurement channel along with other process variables. Methods are also disclosed, including methods to adjust flow conditions in the measurement channel in order to verify accuracy of the inferred flow rate. The inferred flow rate may be used to control process variables in other downstream or upstream processes, including through application in a broader control schema.

    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.
