Recently, in order to verifyZhonghaida iFlow RP1200 intelligent ADCPThe ability to achieve consistent current measurement performance in various environments is supported by Guizhou HydrologyThe flow measurement demonstration was carried out at the Nanhua Hydrological Station, Xingrenqiao Hydrological Station, Guiyang Hydrological Station and other hydrological stations, with excellent results won the recognition of users. Nanhua Hydrological Station
On the day of the demonstration, the site river was about 43m wideThe average flow rate is about 06m/s, the maximum flow rate is about 12m s, the average water depth is about 08m, the total flow is about 20m s. 
Nanhua Hydrological Station Environment.
The specific measurement results of the rounding are as follows:
From the above, it can be seen that in the current environment,The water depth is only 0At 4m, 3 effective layers can still be obtained, and the maximum relative deviation of the four and a half measured flows measured by the equipment is -218%, and the measured proportion exceeded 60%., in line with current measurement specifications and customer requirements.
Xingrenqiao Hydrological Station
On the day of the demonstration, the site river was about 60m wide and had an average flow velocity of about 02m s, the maximum flow rate is about 07m/s，The average water depth is about 3m, the total flow rate is about 39m s. On the day of the test, during the nearly one-and-a-half-hour test process of multiple measurements, the water level changed significantly due to the influence of upstream hydraulic buildings. 
Xingrenqiao Hydrological Station Environment.
The specific measurement results of the rounding are as follows:
According to the real-time water level information of the hydrological station, the flow rate and flow rate changed during the measurement process, and the change trend is shown in the figure below. 
As can be seen from the figure,The flow increases with the rise of the water level, and the trend line is basically the same, the flow rate changes rapidly between measurement 9 and measurement 10, and the real-time water level reaches 647 after the end of measurement71m judged that the traffic increased significantly during this period。Therefore, according to the change of water level, the change trend of each return flow is in line with the actual situation.
From the above, it can be seen that in the current environment, the flow change trend measured by the equipment is in line with the hydrological change law of the basin, and meets the flow measurement specifications and customer requirements. Guiyang Hydrological Station
On the day of the demonstration, the station Nanming River, the river width is about 40m, and the average flow velocity is about 086m/s，, the maximum flow rate is about 12m/s, the average water depth is about 11m, the total flow rate is about 39m s. 
Guiyang Hydrological Station Environment.
The specific measurement results of the rounding are as follows:
From the above, it can be seen that in the current environment,The maximum relative deviation of the four and a half measured return flows measured by the equipment is -253%, and the measured proportion is more than 66%., in line with current measurement specifications and customer requirements.

The specific measurement results of the rounding are as follows:
Measurement results of a river section in Nanjing.
From the above, it can be seen that4 half-measured return flow relative deviations. 2%, and the measured traffic accounts for 86%.to meet the requirements of the specification.
A section of the river in Kunming
On the day of the demonstration, the river was about 12 meters wideThe average flow rate is 018m/s, the average water depth is about 11 meter, maximum water depth 12 meters.
The environment of a river section in Kunming.
The specific measurement results of the rounding are as follows:
From the above, it can be seen that4 half-measured return flow relative deviations. 6%、-3.0%, and the proportion of measured traffic is 65%.to meet the requirements of the specification. Through the demonstration, Zhonghaida iFlow RP1200 intelligent ADCPIt realizes the full coverage of various water environments: shallow water + low flow rate, shallow water + high flow rate, medium water + low flow rate, medium water + high flow rate, and flow test of various complex and difficult environments, which solves the pain points of users such as shallow water and low flow rate measurement and closure difficultiesto further broaden the application scenarios. In the future, Zhonghaida will continue to develop hydrological monitoring products with better performance and contribute scientific and technological strength to the high-quality development of water conservancy.
