Product details
1.Introduction to Radar Flow Meter Products
Radar Flow Meter is a non-contact flow measurement device using microwave radar technology. It can simultaneously measure water level, velocity, flow, and cumulative flow.ML3 radar wave fixed-point online flow measurement is a fully automatic flow telemetry system that can monitor the open channel water flow process throughout the entire process.This flow measurement system is not affected by temperature, humidity, rainfall, water depth, muddy water, and floating objects on the water surface.It is very suitable for flow testing under water conditions in open channels such as irrigation areas and rivers.
2.Radar Flow Meter components
Main components
(1) Three-in-one radar water level surface flow velocity and flow;
(2) Telemetry terminal RTU;
(3) Solar power supply system;
(4) Pole and bracket;
(5) Lightning protection grounding.
3.Working principle of Radar Flow Meter
The radar surface flow velocity meter measures the surface flow velocity of the canal water body based on the principle of pulse radar technology.It is also used in conjunction with the radar water level sensor.It is installed at the regular sections of open channels such as rivers and irrigation areas to calculate the flow rate, that is, at the regular section, the velocity of the water flow through the section, and the depth of the water body is measured, and the water flow rate through the section is calculated through mathematical geometric principles.
4.Radar Flow Meter flow measurement station characteristics
The main feature of Radar Flow Meter is to measure flow by non-contact method.It mainly consists of a three-in-one radar water level flow rate flow rate sensor, which is suspended above the channel through a vertical pole mount.By measuring the water level depth and instantaneous surface flow rate of the regular section, the flow rate passing through the section at this moment is calculated.The main features are as follows:
(1) Advantages
It adopts non-contact type and can be installed with water, and is not restricted by channel water flow or accumulation of water;
No water blockage;
Not easily affected by debris and floating objects in the channel;
Not affected by water quality and sediment content;
Suitable for channels with faster flow rates and larger flow rates.
(2) Interference factors
Influence of wind speed: Wind speed can easily cause fluctuations in the water surface, resulting in false alarms and miscalculation;
Slow flow rate: When the water surface flow rate is slower, the measurement error increases;
Wind and sand weather: Wind and sand weather has a great impact on the signal strength of the radar wave, resulting in a large measurement error;
Heavy rainy weather: When encountering heavy rainy weather, radar waves are easily affected by the strong rain, resulting in large measurement errors.
5.Radar Flow Meter Technical Parameters
