摘要： Non-intrusive pressure sensors (14-18) for measuring unsteady pressures within a pipe (12) include an optical fiber (10) wrapped in coils (20-24) around the circumference of the pipe (12). The length or change in the length of the coils (20-24) is indicative of the unsteady pressure in the pipe. Bragg gratings (310-324) impressed in the fiber (10) may be used having reflection wavelength lambda that relate to the unsteady pressure in the pipe. One or more of sensors (14-18) may be axially distributed along the fiber (10) using wavelength division multiplexing and/or time division multiplexing.

摘要： A portable flow measuring apparatus is provided that measures the speed of sound and/or vortical disturbances propagating in a fluid flow to determine a parameter of the flow propagating through a pipe. The apparatus includes a sensing device that includes an array of pressure sensors, which may be removable, used to measure the acoustic and convective pressure variations in the flow to determine a desired parameter. A portable processing instrument processes the signals provided by the sensing array to provide an output signal indicative of a parameter of the fluid flow. The portable processing instrument includes a processor having appropriate processing algorithms to determine the desired or selected parameter(s) of the process flow (12). The portable processing instrument has a user interface to permit the user to select the parameters to be measured in the process flow, and/or more importantly, to enable the user to modify particular parameters or functions in the processor (30) and/or processing algorithms. The user interface (32) also enables a user to modify the code of the algorithm via a graphic user interface (GUI), keyboard and/or user input signal (34).
