Radar Flowmeter

Product description
A small volume radar flowmeter specially designed for flow monitoring of open channels and underground pipe networks in irrigation areas. The water flow rate and water level are measured by microwave technology, and the flow rate and cumulative flow rate of the section are converted according to the built-in software model and algorithm. Using 24GHz and 60GHz microwaves to measure flow velocity and water level respectively, the measurement results are not affected by ambient temperature, air pressure, water vapor, water pollutants and sediments; its outstanding features are small size and low power consumption, especially suitable for solar power and batteries Group power supply and other applications with strict power consumption requirements.


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. It is suitable for a variety of measurement requirements, and can output measurement data of flow rate, water level and flow;

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

4. Convenient configuration software, which can configure various parameters according to actual needs to adapt to different site conditions;

5. Low power consumption, can be powered by solar energy or battery pack, easy to install and less maintenance.
