The signal receiving and transmitting part 1 can display the real-time position through an external receiving end to obtain a motion track so as to calculate the corresponding flow rate. The outer wall of the base 32 and/or the outer surface of the second upright stanchion 4 are provided with rough contact surfaces 33 to increase the resistance in flowing water, so that the moving speed of the buoy approaches the flow speed of water, and the speed measurement accuracy is improved. The gravity center is moved downwards through the balancing weight 5, so that the gravity center is always lower than the horizontal plane, the device can be always in a state that the upper part of the device faces upwards, the signal of the signal receiving and transmitting part 1 is stable, and the reliability of the device is improved. Specifically, the counterweight 5 is provided with a pull-and-insert portion 51 to change the weight of the counterweight so that the counterweight can be used in water with different densities.
