▋ Measurement Method
BOY-WF08 radar flowmeter is mainly composed of radar current meter and radar water level meter. The current meter is used to collect the fluid surface velocity, and the average flow rate of the water through the model calculation is obtained, and the outflow section area is calculated by combining the water level and section information measured by the water level meter. The flow rate is obtained by the formula flow = average flow rate × flow through section area × correction factor. The correction coefficient is calculated according to the standard value obtained from the actual measurement environment.
▋ Installation Method
1, When the equipment is installed, the probe can not be blocked, which will affect the measurement accuracy.
2, When installing, try to ensure that the upper surface of the shell is horizontal, and installed in the middle of the channel.
3, The current meter beam is recommended to face the direction of the incoming water, and the horizontal Angle with the direction of the water flow is 0 degrees.
4, The current meter is only affected by the dynamic target, the channel hardening treatment without weeds or trees, even if the beam shines on both sides of the channel will not affect the flow measurement.
▋ Application
The equipment can be used in river, irrigation channel, underground drainage network, flood prevention and early warning 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.
