Ultrasonic probes are provided to abate unwanted signal noise. An ultrasonic probe includes a bundle of rods configured to sample data at a first end and propagate a signal encoding the sampled data to a second end. Each of the rods in the bundle of rods has a substantially similar length and a substantially similar diameter. The ultrasonic probe also includes a shell concentrically disposed around the bundle of rods. The shell is configured to pack the bundle of rods together. The shell includes a plurality of grooves configured to abate a prevailing bulk wave sampled by the first end.

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.
