摘要： This application discloses a fluid measuring method and device and electronic equipment. When a fluid flows in a target pipeline, high-speed cameras obtain a first sampling image set of a tracer particle cluster in the fluid passing a front end of the target pipeline and a second sampling image set of the tracer particle cluster passing a rear end of the target pipeline, thereby obtaining passing time distribution information of the tracer particle cluster passing through the target pipeline. A mean residence time of the fluid in the high-pressure target pipeline is obtained based on the passing time distribution information. In this way, the accuracy of non-intrusive online measurement of the mean residence time of the supercritical pressure fluid in the pipeline is improved.

摘要： The present invention relates to a device, a system and a method for monitoring river flow velocity based on differential pressure measurement, comprising: a hull floating on a water surface with an aspect ratio of the hull being greater than one, characterized in that pressure sensors are respectively provided on an upstream face of a front end and a downstream face of a rear end below the floatation line of a ship; an electronic instrument is provided in the hull, and the electronic instrument comprises an acquisition module connected to the two pressure sensors, the acquisition module being connected to a data processing module with a memory, and the data processing module being connected to a satellite positioning module and a wireless communication module. According to the present invention, the flow velocity of water flow is measured based on the difference between the the simulated measured upstream face pressure at the bow and the simulated measured downstream face pressure at the stern by an unpowered measuring ship drifting on the water surface. The measured data is transmitted to the data processing center on the ground via the wireless communication network. The present invention enables the flow data to be measured in presence of poor satellite positioning signals and public network signals or no signals, achieving data transmission independent of satellite positioning and public communication networks.

摘要： Methods and systems are provided for utilization of vehicle speed and barometric pressure sensors. In one example, a method may include measuring a change in a barometric pressure resulting from a measured change in a vehicle speed, modeling the change in the barometric pressure based on a change in a ram-air pressure resulting from the change in the vehicle speed, and indicating a degraded barometric pressure measurement when a difference between the measured and the modeled change in the barometric pressure is greater than a threshold pressure difference.

摘要： A monitoring device includes a cavity assembly with a plurality of cavities. Openings of the plurality of cavities are distributed about a flow-facing surface of the cavity assembly. A gas pressure sensor is disposed within each of the cavities, and is configured to measure an absolute pressure of a gas flow which flows past the monitoring device. Gas pressure measurements from the pressure sensors may be used to determine a flow speed and a flow direction of the gas flow. More specifically, a mapping may be used to map the logarithm of the difference between the maximum and minimum pressures to a flow speed. Further, a lookup table may be used to map a pattern of pressure measurements to a flow direction.

摘要： A vehicle guidance system, including: sensors to detect a surface pressure distribution for a respective location of the corresponding sensor on a vehicle, respectively; and a controller to receive an initial value for a Mach number; and calculate a converged value for an angle of attack based on first surface pressure data from a first set of the sensors, and a converged sideslip angle value based on second surface pressure data from a second set of the sensors. The controller calculates a freestream dynamic pressure based on the initial Mach number, the converged angle of attack, and the converged sideslip angle value, and calculates a freestream pressure, and calculates a converged value for Mach number based on the freestream pressure and the freestream dynamic pressure. A flight control processor provides an output for adjusting an orientation of the vehicle based on the converged Mach number and the freestream pressure.
