ABSTRACT:
A first measurement unit for untrasonically measuring a flow velocity, a river depth, and an ultrasonic velocity is mounted on floating members. The floating members are connected with a travelling unit for automatically travelling a propeller flowmeter which is used in advance, to thereby measure vertical average flow velocities and river depths at a plurality of positions while moving along a river width. The floating members are provided with ultrasonic vibrators in the center thereof for measuring a river depth and an ultrasonic velocity as well as with ultrasortie vibrator pairs for measuring flow velocities. A second measurement unit for measuring an ultrasonic pulse propagation time period has a unit for calculating an ultrasonic velocity, a river depth, a partial flow quantity and an entire flow quantity, and a unit for controlling movements of the floating members and a distance between the ultrasonic vibrators. The second measurement unit is mounted in a flow quantity measurement post, connected to the first measurement unit and a high frequency cable line and supplies electric power to the first measurement unit.
