New laboratory measurements and numeric model studies show
the present folded-path ATT current meters are stable and
sensitive, but are not well suited for mean flow observations
in surface gravity waves. Alternate designs which reduce
unwanted wake effects are proposed. ATT flowmeter history,
principles of acoustic flow sensors, mean flow near cylinders,
and the need for linear flow sensors are reviewed.
