Abstract
A multimode flow meter can use both the time-of-transit of upstream and downstream ultrasonic signals and time for transmission of downstream-only signals to determine a flow velocity of a medium flowing through a conduit. Based on factors, such as previously computed flow velocity and signal-to-noise ratio of the upstream signal, a mode of operation may be switched and only the time for transmission of the downstream signals may be used to determine flow velocity. The multimode flow meter can compute cross-flow to reduce its effect on the determination of flow velocity.
