Stream Gaging - Flowtracker

When a stream is at a stage that can be safely waded, a Sontek Flowtracker ADV is used to measure the discharge. The ADV is a small two pronged acoustic meter that measures the velocity at a single point. The same procedures are used as with a convention current meter. The user inputs the depth and station in the river cross section into a small unit mounted on the wading rod. The unit does all the calculations to compute a final discharge of the stream. There are no moving parts, as with a current meter.
