For wider river channels, such as spillway channels of reservoirs, ship navigation channels under dams, spillway channels of hydropower stations, and rivers, the flow velocity from the two banks to the middle is different. If measuring flow rate is necessary, it becomes even more complex because the flow rate and flow rate vary at different locations. In general, this situation requires data collection from multiple points using at least three sensors.
In the river channel, if there is no sediment, we install the sensor in the center of the bottom of the pipeline. If there is sediment, install the sensor next to the sediment. In order to prevent water flow from impacting and changing the installation position of the sensor, there is a base at the bottom of the sensor, which is specifically used to fix it on the pipeline. At the same time, sensors should be installed in the river near the manhole, which is convenient for installation, maintenance, and replacement.
Requirements for upstream and downstream river channels: There should be a straight river channel with a width of 10 times the width of the river channel upstream of the sensor; If there are gates and pumps upstream, there should be a straight river channel 30 times the width of the river channel between the sensor and the gates and pumps. Downstream of the sensor, there should be a straight river channel with a width of 5 times the width of the river.
