摘要： A method and apparatus for sensing a fluid flow within a pipe is provided. The method includes the steps of: a) providing an ultrasonic sensor having a transmitter operable to transmit ultrasonic signals through the first pipe wall, the fluid flow disposed within the pipe, and the second pipe wall, and a receiver operable to receive the transmitted signal after the signal has passed through the pipe walls and fluid flow; b) disposing the transmitter adjacent the first wall and the receiver adjacent the second wall; c) disposing at least one acoustic member between at least one of the transmitter and the first wall, and the receiver and the second wall, which acoustic member has acoustic properties such that the combined respective member and pipe wall have half wave resonant frequencies that substantially match the half wave resonant frequencies of the opposite wall, or opposite wall and respective member; and d) sensing the fluid flow through the pipe walls and structure using the ultrasonic sensor.

摘要： A flow measuring system is provided that provides at least one of a compensated mass flow rate measurement and a compensated density measurement. The flow measuring system includes a gas volume fraction meter in combination with a coriolis meter. The GVF meter measures acoustic pressures propagating through the fluids to measure the speed of sound αmix propagating through the fluid to calculate at least gas volume fraction of the fluid and/or the reduced natural frequency. For determining an improved density for the coriolis meter, the calculated gas volume fraction and/or reduced frequency is provided to a processing unit. The improved density is determined using analytically derived or empirically derived density calibration models (or formulas derived therefore), which is a function of the measured natural frequency and at least one of the determined GVF, reduced frequency and speed of sound, or any combination thereof. The gas volume fraction (GVF) meter may include a sensing device having a plurality of strain-based or pressure sensors spaced axially along the pipe for measuring the acoustic pressures propagating through the flow.

摘要： A flow measuring system combines a density measuring device and a device for measuring the speed of sound (SOS) propagating through the fluid flow and/or for determining the gas volume fraction (GVF) of the flow. The GVF meter measures acoustic pressures propagating through the fluids to measure the speed of sound αmix propagating through the fluid to calculate at least gas volume fraction of the fluid and/or SOS. In response to the measured density and gas volume fraction, a processing unit determines the density of non-gaseous component of an aerated fluid flow. For three phase fluid flows, the processing unit can determine the phase fraction of the non-gaseous components of the fluid flow. The gas volume fraction (GVF) meter may include a sensing device having a plurality of strain-based or pressure sensors spaced axially along the pipe for measuring the acoustic pressures propagating through the flow.

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.
