Abstract

The invention provides a flow monitoring device and a hydrologic monitoring device and relates to the technical field of hydrologic equipment. The flow monitoring device comprises a flow velocity detection module, a distance acquisition module and a lifting component, wherein the flow velocity detection module is mounted on the lifting component and used for detecting flow velocity of water flow, the distance acquisition module is used for acquiring a distance between the flow velocity detection module and the water surface, and the lifting component is used for driving the flow velocity detection module to ascend and descend when the distance between the flow velocity detection module and the water surface does not correspond to a preset distance. The flow monitoring device is capable of adjusting the distance between the flow velocity detection module and the water surface timely when a water body changes in depth to improve computing accuracy of hydrologic monitoring data such as mean velocity in section, so that error of the hydrologic monitoring data is reduced and the accuracy of the hydrologic monitoring data is improved effectively.

Description

technical field [0001] The invention relates to the technical field of hydrological equipment, and relates to a flow monitoring device and a hydrological monitoring device with the flow monitoring device. Background technique [0002] Hydrological monitoring refers to a complex and comprehensive system engineering that monitors, measures, analyzes and warns of the temporal and spatial distribution and variation of natural water through scientific methods, and is a comprehensive discipline. The hydrological monitoring device is suitable for the hydrological department to conduct real-time monitoring of hydrological parameters such as rivers, lakes, reservoirs, channels and groundwater. The monitoring content includes: water level, flow, flow velocity, rainfall, evaporation, sediment, ice, moisture, water quality, etc. It plays an irreplaceable role in urban flood control dispatching and water resource management and protection. [0003] The current meter is a kind of equipme...
