③ River types correspond to different algorithm processing, here you can select the default “normal";
④ Choose the corresponding value of the shore coefficient according to different materials, the default value
is 1, if you don't confirm, just follow the default parameters;
⑤ Flow rate measurement gear, corresponding to different measurement ranges:
1——Used for ultra-low speed precise measurement (less than 0.1m/s, reserved);
2——0.03~10m/s conventional flow velocity measurement (system default value);
3——0.1~20m/s wide range velocity measurement, accuracy is slightly lower than 2.
⑥ The radar wave direction of the flow velocity radar sensor is divided into automatic, downstream, and
upstream. It is used to set different flow velocity directions. Oncoming is upstream. It is recommended to
install upstream (default), with rain resistance; if you choose automatic or downstream , The rain-resistant
mode is invalid;
⑦ The noise threshold of the flow rate radar sensor is used to set the signal extraction threshold. If the
signal strength (available in real time on the main interface) is lower than the set value, it is considered to be
noise and not picked up; this parameter usually does not need to be adjusted; only when the installation
distance is long and the flow rate is low, the signal is weak, and it needs to be adjusted according to the field
signal strength. The threshold setting of the flow rate radar sensor should not be less than 400;
⑧
The number of filtering times corresponds to the wave-eliminating effect, the larger the wave-eliminating
effect is, the more stable the measurement result is, but the real-time performance will be weakened, and the
default is normal;
⑨ The horizontal angle setting is used for the angle that needs to be corrected when the flowmeter is
installed on the bank, not directly above the river, and has a certain angle with the flow direction of the river;
although this installation is not recommended, the device still provides a correction option, the default Is 0°;
⑩
The rain mode has certain requirements for the installation direction of the device, and the river needs to
face the flowmeter. If you need to measure downstream or bidirectional flow, the rain mode will fail; the
device defaults to the rain mode;
⑪ Sleep time is to set the time for the flow meter to enter the low-power sleep mode, and stop
measurement during this period. Measure and accumulate the flow again after the sleep time is
automatically awakened. It is generally used in low-power application environments and the unit is minutes;
