With its high precision, reliability, and unmanned operation, it comprehensively empowers river-lake-reservoir monitoring, urban water management, and disaster prevention and reduction
[Global Hydrological Technology Frontier] Recently, the global hydrological monitoring equipment market has reported exciting news: the new generation of hydrological radar flowmeters has seen explosive sales growth due to its groundbreaking technological advantages, becoming the preferred choice for water conservancy departments, environmental agencies, and smart city contractors worldwide. The popularity of this device marks a new era in hydrological monitoring, transitioning from “contact-based” to “non-contact” integration of “space-air-ground” systems.
Technological Innovation: The Core Driver Behind Its Popularity
Traditional flow measurement methods, such as current meters and ADCP, require sensors to be placed in the water, making them susceptible to debris impact, sediment accumulation, and corrosion. These methods involve high maintenance and safety risks. The success of hydrological radar flowmeters lies in their ability to perfectly address these long-standing industry pain points, with core advantages including:
Truly Non-Contact Measurement: The device uses 24GHz/60GHz high-frequency radar wave technology. It only needs to be installed on a bridge or above the water surface to remotely detect flow velocity. The sensor never touches the water, completely avoiding risks of being washed away by floods, buried in sediment, or corroded, significantly extending its lifespan.
High Precision and Comprehensive Data: Through advanced radar signal processing algorithms, it can simultaneously measure surface flow velocity and water level (optional), with built-in computational models to directly output instantaneous flow and cumulative flow. Its accuracy far exceeds industry standards, meeting the requirements for Grade 1 hydrological stations.
Easy Installation and Low Maintenance: Installation does not require expensive flumes, weirs, or flow interruption, greatly reducing engineering complexity and initial costs. Post-installation, it is almost maintenance-free, significantly lowering the risks and costs of field operations.
Strong Environmental Adaptability: It performs reliably under extreme conditions such as heavy rain, floods, freezing temperatures, turbid water, algal blooms, and floating debris, providing continuous and dependable data.
Smart IoT and Seamless Integration: Built-in 4G/5G and LoRa communication modules support remote configuration, diagnostics, and real-time data transmission. Data can be seamlessly integrated into national hydrological platforms, smart water management clouds, and private monitoring systems, enabling digital and intelligent watershed management.
Application Scenarios: Comprehensive Protection from Rivers to Urban “Blood Vessels”
The popularity of hydrological radar flowmeters stems from their wide range of applications and irreplaceability, making them “guardians of flow monitoring” in multiple critical fields:
River and Reservoir Hydrological Monitoring: Serves as the core equipment for online flow monitoring stations in natural rivers, reservoir outlets, and water conveyance channels. It is particularly suitable for mountainous rivers with rapid water level changes and high sediment content, providing key data for flood control and water resource allocation.
Urban Smart Water Management and Flood Warning: Installed at critical points such as urban drainage networks, sewage treatment plant inlets/outlets, and river culverts, it monitors drainage flow in real time, providing core input data for urban flood warning models and supporting “smart drainage” and “sponge city” initiatives.
Modernization of Small and Medium-Sized River Monitoring: As countries promote the modernization of hydrological monitoring systems for small and medium-sized rivers, radar flowmeters are the preferred solution for rapid deployment and filling monitoring gaps due to their easy installation and maintenance-free operation.
Environmental Monitoring and Ecological Flow Management: Used to monitor ecological discharge flow and industrial wastewater discharge, providing precise quantitative data for environmental enforcement and water ecosystem protection.
Agricultural Irrigation and Water Conservancy Projects: Installed on main and branch canals of large irrigation districts, it enables precise measurement and efficient allocation of water resources, promoting water-saving irrigation.

A director of a provincial water resources bureau stated: “In the past, measuring flow during flood season required field staff to operate instruments in dangerous floodwaters. With radar flowmeters, we can now access real-time data from our offices, greatly ensuring safety while significantly improving data timeliness and continuity. This is a critical step forward in our hydrological modernization efforts.”
Currently, the product has been successfully applied in major domestic and international projects, such as China’s South-to-North Water Diversion Project, the Yangtze River Basin hydrological station network upgrade, and Thailand’s Chao Phraya River flood warning system, receiving high acclaim from the industry. Analysts predict that as hydrological monitoring requirements increase against the backdrop of global climate change and investments in smart water conservancy under “new infrastructure” initiatives grow, the demand for hydrological radar flowmeters will continue to rise rapidly, with broad industry prospects.
