摘要： In a method for monitoring a fluid flowing in a pipeline, a dynamic model of the flowing fluid is provided. At least one operational parameter forming part of the dynamic model is provided for measurement. At least one sonar-based sensor is coupled to the pipeline and is operable to measure the operational parameter. This sensor is also operable to generate signals indicative of the operational parameter. A controller is in communication with the sensor and is associated with the dynamic model. The controller receives the signals generated by the sensor, interprets and compares these signals to the dynamic model, and determines when the operational parameter has deviated from values corresponding to the operational parameter forming part of the dynamic model. The operational parameter can be a speed of sound of the fluid flowing in the pipeline, pressure, temperature, pump speed, flow rate, or the like.

摘要： An apparatus for measuring compositional parameters of solid, liquid, and gas components of a mixture flowing in a pipe is presented. The apparatus combines three different compositional measurements (e.g., the speed of light (microwave), the speed of sound (sonar), and mass loading of vibrating tubes or absorption of radiation) simultaneously to provide a real time, multi parameter, compositional measurement of gas-entrained mixtures.

摘要： Various methods are described for measuring parameters of a stratified flow using at least one spatial array of sensors disposed at different axial locations along the pipe. Each of the sensors provides a signal indicative of unsteady pressure created by coherent structures convecting with the flow. In one aspect, a signal processor determines, from the signals, convection velocities of coherent structures having different length scales. The signal processor then compares the convection velocities to determine a level of stratification of the flow. The level of stratification may be used as part of a calibration procedure to determine the volumetric flow rate of the flow. In another aspect, the level of stratification of the flow is determined by comparing locally measured velocities at the top and bottom of the pipe. The ratio of the velocities near the top and bottom of the pipe correlates to the level of stratification of the flow. Additional sensor arrays may provide a velocity profile for the flow. In another aspect, each of the sensors in the array includes a pair of sensor half-portions disposed on opposing lateral surfaces of the pipe, and the signal processor determines a nominal velocity of the flow within the pipe using the signals.
摘要翻译：描述了用于使用布置在沿着管的不同轴向位置处的至少一个传感器空间阵列来测量分层流的参数的各种方法。每个传感器提供指示由与流动对流的相干结构产生的不稳定压力的信号。在一个方面，信号处理器根据信号确定具有不同长度尺度的相干结构的对流速度。然后，信号处理器比较对流速度以确定流动的分层水平。分层的水平可以用作校准过程的一部分，以确定流量的体积流量。在另一方面，通过比较管道顶部和底部的局部测量的速度来确定流动的分层水平。管道顶部和底部附近的速度比与流动分层的水平相关。附加的传感器阵列可以为流提供速度分布。在另一方面，阵列中的每个传感器包括设置在管道的相对侧表面上的一对传感器半部分，并且信号处理器使用信号确定管道内流动的标称速度。

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 α mix 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 system of one or more configurable flowmeters allows an individual, locally or remotely, to selectively activate one or more functions of the flowmeters. The individual is capable of selecting which parameter of the process flow that the flowmeter is to measure, thereby effectively providing latent functions that may be selectively brought on line or shut off. The system may also allow an individual, locally or remotely, to selectively activate one or more latent flowmeters in the system. The system may be a distributed control system (DCS), which receives input signals from conventional meters and devices in the process flow and provides control signals to one or more devices in the flow process. The system may also provide a method of flowmeter selection and billing.
