Abstract
A flow sensor system is provided for measuring the rate of flow of a fluid in a flow channel that is configured to contain the flow. A substrate may be disposed in the flow channel, and a plurality of transducers may be disposed on the substrate in the flow channel. The substrate may also provide a plurality of paths, and each path may conduct a signal. The transducers may be configured to respond to the fluid flow by modifying the signals in relation to the flow. The transducers may be arranged with at least one of the transducers disposed closer to a central longitudinal axis of the flow channel than at least one other transducer. A signal processor may be coupled to at least two of the signals, and the signal processor may calculate the rate of flow of the fluid as a function of the at least two signals.
