Integrated Radar Flowmeter

Product description
An integrated radar flowmeter based on microwave technology. It adopts advanced K-band planar radar technology to measure the flow velocity and water level of water bodies in a non-contact way. According to the built-in software model and algorithm, it calculates and outputs real-time cross-section instantaneous flow and cumulative flow; it can be used for river channels, irrigation canals, and underground drainage pipes. Non-contact flow measurement is carried out on network, flood control and early warning; the product has the characteristics of low power consumption, high reliability, and convenient maintenance; the measurement process is not affected by factors such as temperature, sediment, river pollutants, and floating objects on the water surface. The product integrates RTU and Bluetooth functions, which can realize data collection and wireless upload, remote parameter adjustment, maintenance, and equipment upgrades. At the same time, parameters can be set through the mobile APP on site, the measurement results can be read, and the data can be easily uploaded to the cloud or server.


1. Non-contact measurement, combined with section parameters to calculate flow, not affected by wind, temperature, haze, sediment, floating objects, etc. With rainproof mode;

2. Applicable to a variety of measurement conditions, and can output measurement data of flow rate, water level, and flow rate;

3. Scalable array multi-point flow measurement, equipped with one set of flowmeter and multiple sets of velocity meters, and through the internal algorithm fitting of the flowmeter, the flow measurement of wide cross-section can be realized;

4. It is suitable for trapezoidal, circular, U-shaped, and other cross-sections, and the setting method of cross-section parameters is simple and convenient;

5. Convenient configuration software, which can conveniently configure parameters according to actual needs to adapt to different conditions of use;

6. Integrated RTU function, data is directly uploaded to the server, simplifying the difficulty of system integration;

7. Built-in low-power Bluetooth, you can directly debug and set parameters on-site through the mobile APP without computer connection;

8. You can adjust parameters, upgrade, and maintain remotely without going to the site, which greatly reduces maintenance costs.
