Radar flowmeter

Radar flowmeterBased on the principle of Doppler effect, the water flow velocity is accurately calculated by emitting high-frequency electromagnetic waves and capturing the frequency shift of the reflected waves on the surface of the water flow. Its non-contact measurement method does not require immersion in water, which can avoid interference from sediment and floating objects and adapt to complex hydrological environments. The device integrates water level and flow velocity measurement functions, combined with built-in algorithms to achieve real-time flow calculation, and supports multiple cross-sectional parameter settings such as trapezoidal and circular shapes. Featuring low power consumption, compact size, and easy installation, it is suitable for scenarios such as rivers, irrigation channels, flood warning, and emergency monitoring, providing reliable data support for water management.

5、 Product installation diagram

The installation diagram is shown in the figure. On site installation can be carried out with the help of existing building foundations such as bridges and brackets, but it is necessary to ensure that the direction of the radar wave emitted by the flow meter is parallel to the direction of the water flow. The wave emitted by the flow meter is at a 45 ° angle to the water surface, and the default adjustment angle at the factory is 45 °

6、 Installation precautions

1. Installation requires selecting a stable flow state, on a straight channel, away from the gate outlet, and at the channel bend position

2. The installation height should be controlled within 5 meters as much as possible (the closer the distance, the stronger the measurement signal and the more reliable the data)

3. If the water flow rate is below 0.25 and the water ripple is small, there is feasibility for unstable measurement
