Abstract:
1. A flow sensor assembly comprising: a flow conduit configured to allow fluid flow therethrough; a flow disturber disposed in the flow conduit, the flow disturber configured to impart a flow disturbance to the fluid flow; a plurality of flow sensors disposed in the flow conduit, the plurality of flow sensors being responsive to flow characteristics in the flow conduit; a frequency resolver coupled to the plurality of flow sensors, the frequency resolver configured to determine frequency information related to the fluid flow based on the flow characteristics, the frequency resolver using one or more time sample windows to select data samples from the plurality of flow sensors for use in determining the frequency information, a length of one or more of the time sample windows based at least in part on the flow characteristics; and a processor coupled to the plurality of flows sensors and the frequency resolver, the processor configured to determine a flow rate of the fluid flow in the flow conduit using the frequency information.
