The flow monitoring station is a smart river flow monitoring instrument featuring integrated design. The system is composed of a river channel radar flowmeter, telemetry terminal unit, and other components. The radar flowmeter utilizes advanced K-band planar radar technology to measure water flow velocity and water level in a non-contact manner. Through built-in software algorithms, it calculates and outputs real-time cross-sectional flow rate and total accumulated flow. This device is suitable for applications including rivers, irrigation canals, underground drainage networks, and flood warning systems.
2. Function

3. Installation Instructions
3.1 Installation Preparation
As the equipment is installed in an open river channel environment, the device is waterproof, and the mounting pole must be constructed with anti-corrosion materials or treated with anti-corrosion measures.
Equipment cabling should be routed internally through the pole; exposed outdoor wiring is prohibited.
When installing the pole, the foundation must be poured with concrete and allowed to fully cure before mounting the pole.
Before finalizing the installation location, verify that on-site communication conditions meet data transmission requirements.
1. High precision and reliable
The device employs Doppler planar microstrip array antenna with CW+PCR measurement technology (Continuous Wave + Pulse Coding Radar), with high precision and excellent stability. Its non-contact measurement method calculates flow rates through cross-sectional parameter analysis, No interference from wind, temperature, haze, sediment, or floating debris. The system also features rain-resistant operation mode for all-weather reliability.
2. Ultra-low power consumption with high versatility
The device features ultra-low power consumption and exceptional versatility, adaptable to trapezoidal, circular, U-shaped, and other channel cross-sections with simplified parameter configuration.
3. Easy installation and convenient O&M
The device adopts an integrated design with a simplified stainless steel mounting pole, providing easy installation and minimized maintenance requirements.
