Portable Doppler Flow Meter Meets Needs for Precise Hydrological Monitoring Across Diverse Scenarios

Operating on the principle of the ultrasonic Doppler effect, this portable Doppler flow meter is suitable for monitoring rivers, open channels, and pipelines. It features high precision, low power consumption, and ease of maintenance, enabling the simultaneous collection of flow velocity, water level, and temperature data. With data storage and export capabilities, it is well-suited for a wide range of hydrological monitoring tasks.

This portable Doppler flow meter is a professional instrument widely used in water conservancy and environmental protection. It is designed for various water body conditions—including rivers, natural streams, artificial open channels, municipal pipelines, and discharge outlets—to provide integrated measurement of flow velocity, flow rate, water level, and temperature. It effectively overcomes the limitations of traditional mechanical flow meters, such as susceptibility to wear, frequent maintenance requirements, and poor environmental adaptability. The device utilizes the acoustic Doppler effect to detect flow; a probe captures frequency shifts in sound waves caused by water movement to precisely calculate velocity. Simultaneously, built-in sensor modules collect water level and temperature data. The monitoring process is stable and minimally affected by environmental factors such as temperature fluctuations or impurities in the water.

Featuring a portable design, the device pairs a single flow sensor with a simple installation mechanism, ensuring exceptional versatility. It is suitable not only for standard, uniform river channels and full-pipe flows but also for complex scenarios such as partially filled pipes, irregular channels, and concealed discharge outlets. It supports covert installation and enables stable, long-term, unattended monitoring. Equipped with a 2.8-inch color display, the device presents data through a combination of text and graphics, allowing operators to intuitively view real-time flow conditions and parameters, thereby simplifying field operations and data analysis.

In terms of performance and practicality, the device offers comprehensive measurement capabilities. Its accuracy for flow velocity, water depth, and flow rate meets industry standards for hydrological monitoring, and it simultaneously outputs both instantaneous and cumulative flow data. It features large-capacity storage capable of holding tens of thousands of data records and includes a USB export function, facilitating subsequent data organization, archiving, and analysis by personnel. With low power consumption and a built-in rechargeable lithium battery, the sensor ensures an exceptionally long operating life, fully meeting the demands of extended field inspections. The device supports one-touch switching between Chinese and English interfaces, accommodating diverse usage scenarios and operator needs. Thanks to its high reliability and low maintenance costs, it is a preferred choice for applications such as "Sponge City" development, "River Chief" system management, inland waterway ecological monitoring, and hydrological control in aquaculture.
