1.Radar Flow Meters product introduction
Radar Flow Meters use a non-contact monitoring method to monitor water velocity, water level and water volume data in rivers and open channels.The Radar Flow Meters developed by our company adopts K-band planar microstrip array antennas, which are concentrated in energy and have low power consumption.The instrument integrates functions such as vertical angle compensation, flow rate average, signal strength detection, serial communication control, etc.The equipment is not corroded by sewage and is not affected by sewage during the speed measurement of the contactless radar flow measurement system.The equipment is simple in civil engineering and less affected by water damage, which is easy to maintain and ensures personnel safety.It can not only be used for daily environmental monitoring, but also especially suitable for emergency and difficult observation tasks.
2.Radar Flow Meters product features
1.Non-contact, low safety, less maintenance, and no influence from silt
2.Be competent for the measurement of high flow velocity during flooding
3.It has anti-reverse connection and overvoltage protection functions
4.The system consumes low power, and the general solar power supply can meet the current measurement needs
5.Various interface methods, both digital and analog interfaces, compatible with the standard Modbus-RTU protocol to facilitate access to the system;
6.It has wireless data transmission function (optional)
7.It can be connected to the current urban water conditions, sewage and environmental automatic reporting system.
8.The speed measurement range is wide, and the effective measurement distance is up to 10m
9.Multiple trigger modes: periodic, trigger, manual, automatic
10.The installation is very simple and the amount of civil engineering is very small.
11.Fully waterproof design, suitable for outdoor use

5.Radar Flow Meters product installation diagram




The installation diagram is shown in the figure.On-site installation can be achieved by bridges, brackets and other existing building foundations, but it is necessary to ensure that the emission direction of the flowmeter radar wave is parallel to the direction of the water flow, and the emission wave of the flowmeter is 45 to the water surface.The factory defaults to adjust the angle of 45°.
6.Precautions for installing Radar Flow Meters
1.Installation requires the selection of stable flow state, straight channel, away from the gate outlet, channel elbow position
2.Try to control the installation height within 5 meters (the closer the distance, the stronger the measurement signal and the more reliable the data)
3.The water flow rate is less than 0.25, and the water ripple is small, so it is feasible to measure unstable
