6.3. Beam Check
Beam Check operates by sending a pulse of sound into the water, and then plotting the
signal to noise ratio of the return signal versus range for each of the FlowTracker2
receivers. This information can be evaluated to determine the effective measurement
range, to look for interference from boundaries/structures, to survey a deployment site,
or to observe the quality of the returned signal.
