摘要： The present invention relates to a device, a system and a method for monitoring river flow velocity based on differential pressure measurement, comprising: a hull floating on a water surface with an aspect ratio of the hull being greater than one, characterized in that pressure sensors are respectively provided on an upstream face of a front end and a downstream face of a rear end below the floatation line of a ship; an electronic instrument is provided in the hull, and the electronic instrument comprises an acquisition module connected to the two pressure sensors, the acquisition module being connected to a data processing module with a memory, and the data processing module being connected to a satellite positioning module and a wireless communication module. According to the present invention, the flow velocity of water flow is measured based on the difference between the the simulated measured upstream face pressure at the bow and the simulated measured downstream face pressure at the stern by an unpowered measuring ship drifting on the water surface. The measured data is transmitted to the data processing center on the ground via the wireless communication network. The present invention enables the flow data to be measured in presence of poor satellite positioning signals and public network signals or no signals, achieving data transmission independent of satellite positioning and public communication networks.
