摘要： A signal processor receives a signal containing information about a sensor that is spirally wrapped at a known pitch or separation down a pipe having a flow; and determines a flow velocity based at least partly on the information contained in the signal received by applying an autocorrelation function that depends on a relationship between the time between a repeating pattern and the known pitch or separation of the spirally wrapped sensor. The signal processor provides a corresponding signal containing information about the flow velocity. The sensor includes a strain sensor, including a piezo-electric polymer strain sensor fabricated from PVDF, and/or two or more equally spaced spirally wound sensors. The determining includes correlating output signals of two or more equally spaced spirally wound sensors to determine a time delay, and determining the flow velocity based on the time delay and the known pitch or separation.

摘要： Fluid flows through a conduit. To measure flow speed the fluid is heated at a heating location in the conduit with a time-dependent heating strength. A speed of sound in fluid flowing in the conduit is measured at a plurality of sensing locations downstream from said heating location. The flow speed of the fluid is determined from a delay with which the time dependence is detected in the sound speeds measured at said sensing locations. In an embodiment a frequency of the variation of heating strength that is used to determine the flow speed is selected automatically dependent on the flow speed and/or other circumstances.

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： 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.
