▋ Product Description

      BOY-WF08-02 is an integrated non-contact measurement of water level and velocity, using Doppler radar K-band technology, built-in high-precision velocity and water level sensors, with horizontal and vertical Angle compensation, which can calculate instantaneous flow and cumulative flow in real time.



▋ Product Characteristics

a. microwave radar is not subject to temperature gradient, pressure, low air. 

b. non-contact surface flow rate measurement, not affected by sewage corrosion, not affected by sediment, to ensure personnel safety. 

c. easy installation, high reliability, less maintenance, especially suitable for water surface flow rate monitoring. 

d. does not destroy the flow state, measurement speed response is fast, long service life.

▋ Working Mechanism

        BOY-WF08-02 is an automatic radar flowmeter based on Doppler radar K-band technology. It uses advanced K-band planar radar technology to measure water velocity, water level and discharge in a non-contact manner. The device is connected to the host through RS485, and provides wireless signals such as 4G to send measurement data to the server, providing data support for background decision-making. 



▋ Installation Method



▋ Application

           BOY-WF08-02 can be used in river, irrigation channel, underground drainage network, flood prevention and early warning, ecological discharge and other occasions.



▋ FAQ

1.  Why did the host computer not receive any data?

Check whether the power supply voltage is 7 to 32VDC, the device cable connection, and the communication mode, serial port number, and baud rate are correct. Check whether the communication protocol is operated according to the instructions, and check whether the instructions are correct;

2. Why is the measurement value always zero?

Check whether the radar probe is aligned with the measured target; Whether the measuring distance is within the reasonable range of the probe test.

3. Why do the measured values frequently change dramatically?

Check whether the power supply voltage is too low; Whether there are obstacles in the measuring range; Whether the probe is installed firmly, and whether the radar flowmeter is installed in parallel horizontal planes;

4. Why is the measurement value not updated?

Check whether the water surface freezes due to seasonal reasons; Check whether the measurement is inaccurate due to the low water period or the swing of the main trough causing the radar wave to cover the ground.

5. The measured water velocity was visually below 0.60m/s, but the reading was higher than expected.

Check the effect of wind on the water surface. Wind may have an effect on the measurement of low speed water flows, such as those below 0.50m/s. Try to measure by pointing the radar speed probe at the same spot.
