Abstract
Systems and methods for flow sensing in a conduit are provided. One system includes a flow disturber disposed in a flow conduit and configured to impart a flow disturbance to the fluid flow. The system further includes a plurality of flow sensors disposed in the flow conduit and responsive to flow characteristics in the flow conduit. The system also includes a frequency resolver configured to determine frequency information related to the fluid flow based on the flow characteristics. The frequency resolver uses one or more time sample windows to select data samples for use in determining the frequency information, wherein a length of one or more of the time sample windows is based at least in part on the flow characteristics. The system additionally includes a processor configured to determine a flow rate of the fluid flow in the flow conduit using the frequency information.
