Abstract: In large rivers two- or three-dimensional velocity distribution is closely interrelated to channel shaping, bed configuration, suspended sediment, bed load and pollutant trans-port. Proper methods of discharge measurement are also depending on flow direction. Veri-fication of numerical models needs measured data. Flow direction metering was introduced more than twenty years ago in Hungary. Three types of instruments have been used, Ott--Muldedag, Muszkalay-Kranicz (a Hungarian invention) and the current-meter cross. The ap-plicability of these instruments depends on the depth and velocity to be measured. Charac-teristic cases are introduced when one of the instruments was used and the results are demonstrated. It is concluded that conventional current metering should be replaced in several cases by current direction measurement.
