A wind noise analyzer includes: an unsteady computational fluid dynamics calculation unit configured to execute an unsteady computational fluid dynamics simulation involving moving a structure model modeled on a structure, and calculate, for each of spatial nodes, an average flow velocity and an average vorticity over a predetermined time in a flow field inside the predetermined region, and then calculate, for each of the spatial nodes, a value based on an amplitude of a turbulent flow velocity inside the predetermined region, in an angular frequency band of interest; and a pressure source density calculation unit configured to calculate, based on the average flow velocity, the average vorticity, and the value based on the amplitude of the turbulent flow velocity, a pressure source density.

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.

A combined sewer/enclosure overflow (CSO) sensor system is described for accurate detection and measurement of overflow events. From the combined data, trending information can determine if there is debris accumulation. Rain masks can be used in the trending data to measure overall health. External sensors in combination with the CSO sensors provide predictive information and additional levels of information/data accuracy. The sensor system automatically and remotely monitors CSO locations and provides real-time data regarding start times, stop times, duration, and flow volumes of overflows that occur in these structures and provide regulatory and public notification of these events.

A method and device for determining a velocity of a flowing medium that allows an as high as possible measuring accuracy without requiring a complicated measuring construction is achieved in that a vortex is generated in the medium and an electromagnetic signal is emitted into the medium. Then, the permittivity of the medium is determined and the velocity of the medium is determined using the permittivity measurement.

A vortex flow meter is within a flow conduit. The vortex flow meter includes a housing defining a flow passage substantially in-line with the flow conduit. An actuable buff body is within the flow passage. A sensor is downstream of the actuable buff body and is attached to the housing. The sensor is configured to detect vortex shedding. A controller is configured to send a drive signal to an oscillator to oscillate the buff body. The controller is configured to receive a vortex stream from the sensor. The vortex stream is indicative of vortexes shed by the buff body within a fluid. The controller is configured to determine a flow velocity responsive to the received vortex stream.

A field device for monitoring a process variable of an industrial process includes an image capture device. A process component exhibits relative motion as a function of a process variable. The image captures device captures an image which changes due to the relative motion of the process component. An image processor coupled to the image capture device detects relative motion of the process component and measures the process variable based upon the detected relative motion. Output circuitry provides an output related to the measured process variable.
