摘要： A method and a device for simultaneously measuring the flow speed and the depth of a river is provided. The method and the device use ultrasonic wave to measure average flow speeds at a plurality of points in the water flow of a river to measure the flow rate of the river. The device comprises a vertical rod (7), and inclined rod (9), a vertical rod cylinder (8) movable up and down along the vertical rod, an inclined rod cylinder (10), through which the inclined rod can move, installed at an axis fixed perpendicular to the vertical rod cylinder (8), an angle sensor (15) measuring the angle between the vertical rod (7) and the inclined rod (9), support rods (14) installed at said axis and the ends of the vertical rod and the inclined rod (9) opposite to said axis, ultrasonic vibrators (4, 4', 6, 6') installed at the ends of said support rods (14) spaced from the vertical rod and the inclined rod, a level (11) attached to the top of the vertical rod (7), and a calculating part (16). Said device measures the distances between said ultrasonic vibrators (4, 4', 6, 6'), ultrasonic wave propagation times, and the angle between the inclined rod and the water surface and then evaluates the flow rate and the depth of the water from the measured data by the time difference method or the frequency difference method.
