摘要： A method and apparatus are provided for calibrating a flow meter having an array of sensors arranged in relation to a pipe that measures a flow rate of a fluid flowing in the pipe. The method features the step of calibrating the flow rate using a calibration correction function based on one or more parameters that characterize either the array of sensors, the pipe, the fluid flowing in the pipe, or some combination thereof. The calibration correction function depends on either a ratio t/D of the pipe wall thickness (t) and the pipe inner diameter (D); a ratio t/λ of the pipe wall thickness (t) and the eddie wavelength (λ) of the fluid; a Reynolds number (ρUD/μ) that characterizes the fluid flow in the pipe; a ratio Δx/D of the sensor spacing (Δx) and the pipe inner diameter (D); a ratio fΔx/Umeas of usable frequencies in relation to the sensor spacing (Δx) and the raw flow rate (Umeas); or some combination thereof. The apparatus takes the form of a flow meter having a calibration correction function module performing the aforementioned functionality.

摘要： A submersible meter is provided that measures the speed of sound propagating in an aerated fluid to determine any one of a plurality of parameters of the fluid, such as the gas holdup of the fluid (εb), the bubble size (db), the bubble surface area flux (Sb), and the flotation rate constant (k). The meter includes a spatial array of sensors disposed at predetermined axial locations x1-XN axially along a tube. The array of sensors provide acoustic pressure signals P1(t)-PN(t) to a transmitter which determines the speed of sound amix propagating through the aerated fluid in the tube using acoustic spatial array signal processing techniques. The submersible meter enables real time measurement of the bubble size, the bubble surface area flux and flotation rate constant, which enables real time monitoring of the efficiency and recovery rate of flotation machines. A control system is also provided using the submersible meter improve the efficiency of mineral processing by controlling the process parameters in response to the measured parameter of the fluid within a flotation machine.
