Abstract

See full text

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.
