Hydrological and water flow data serve as the core fundamental basis for water conservancy management, flood and disaster mitigation, ecological governance, and agricultural irrigation. The water flow status of various water bodies, such as river channels and tributaries, field canal systems, urban drainage ditches, sewage, and downstream reservoir areas, is directly related to water resource allocation and water area safety management. Traditional hydrological survey work mostly relied on fixed monitoring facilities or conventional manual measurement methods. equipment has fixed locations and cannot be moved, making it difficult to cover scattered, remote, and temporary survey points. Meanwhile, manual measurement is cumbersome, inefficient, and prone to data and monitoring lags. Facing the current demand for refined hydrological management, the shortcomings of traditional survey modes have become increasingly apparent. The widespread application of the WX-LS150 portable flow meter, with its advantages of flexibility, portability, high efficiency, and precision, has become a core tool for routine surveys and emergency water measurements in grassroots water affairs, environmental, and agricultural departments.

Portability, flexibility, and wide scene adaptability are the most core practical values of the WX-LS1500 portable flow meter, making perfectly suitable for various scattered field survey scenarios. Many small and medium-sized ditches, rural tributaries, field canals, and temporary drainage points do not meet the conditions for installing fixed monitoring. Large-scale deployment of fixed facilities is costly and impractical, leaving them in a long-term monitoring vacuum. However, the portable flow meter requires no fixed installation and is not by terrain, site, or environment. It can be carried easily and taken to the field at any time to quickly complete flow velocity and discharge surveys for various open-air, scattered and temporary water bodies.

In routine hydrological census and daily water affairs inspections, the portable flow meter significantly improves the efficiency of grassroots work and achieves a lightweight upgrade of survey operations. manual water flow survey processes are cumbersome, requiring multiple auxiliary tools and several calculation steps to obtain data. A single survey takes a long time, and facing multi-point, large- inspection tasks requires a significant amount of manpower and material resources. This device is simple and easy to operate, requiring no complex professional skills. Grassroots staff can quickly master its operation, the cumbersome traditional survey process and rapidly obtaining accurate core water flow data. Routine tasks such as daily river channel inspections, irrigation area water volume verification, routine water area census, and compliance inspections drainage outlets can all be efficiently completed with the device, greatly shortening the survey duration, reducing the intensity of field operations, and making hydrological inspection work more efficient and convenient.

flood control emergency scenarios, the portable flow meter is a key piece of equipment for rapid assessment of water conditions and assisting in emergency response. After heavy rains, the water flow status of and ditches in various regions changes instantaneously. Localized surges in water flow and abnormal flow velocities can easily trigger safety hazards such as urban flooding, mountain floods, and water accumulation. Accurate rapid on-site water flow data provide important support for flood control decision-making. Fixed monitoring equipment has a limited coverage area and cannot account for sudden hazardous points. In contrast, portable can be quickly brought to the disaster site by maintenance personnel to collect real-time water flow data at the first moment, accurately grasping the trends of water level rises and falls and velocity changes. Staff rely on the measured data to assess the water condition trends, scientifically carry out emergency tasks such as flood discharge and diversion, hazard containment, and personnel evacuation, effectively the timeliness and precision of flood control response, and minimizing various losses caused by flood disasters.
