Automatic Flow Monitoring
Performance Index of ADCP Equipment-Walking ADCP
A. Characteristic of Walking ADCP
(1) The traditional measurement method is static. Whether it is manual ship measurement, cable measurement, etc., the instrument is always fixed on the vertical line for measurement, while ADCP is a dynamic measurement method. It is not limited by the width of the river when measuring the ship's motion.
(2) The traditional method usually requires the flow section to be perpendicular to the river bank, while the ADCP measurement process does not require the flow section to be perpendicular to the river bank, and the ship's trajectory can be diagonal or curve.
(3) Suitable for patrol, single working mode (suitable for all rivers; including the Yangtze River 80 meters deep water), measuring time is short, only a few minutes; flow can be measured in shallow water, the minimum depth can be 0.3 m, the maximum depth can be 100 meters; the minimum velocity can be 1 cm/s; three-dimensional velocity components can be measured.
B. Composition of Walking ADCP System
The cruise ADCP system consists of the following components:
(1) Walking ADCP Probe: Intelligent Multi-frequency FM Walking ADCP
Working frequency: 0.5MHZ~2MHZ
(2) Computer terminals:
(3) Matching software: Chinese interface, the original software can output directly after the measurement without any other post-processing software, including the standard national standard "test results record table" and the hydrological Southern film "measured flow results table".
(4) Configuration of GPS
C. Walking ADCP Function
The system can achieve the following functions:
(1) Conditional real-time monitoring and calculation of local and total discharge of rivers, estuaries, natural streams and hydraulic channels can be carried out.
(2) The flow can be measured by uninterrupted and continuous navigation from any path along the river bank to the opposite bank.
(3) At the same time, the velocity profile of the cross section, the river cross section, the undisturbed flow field, the generation of measurement reports and the automatic intelligent switching of measurement frequency are measured directly.
(4) Automatically and intelligently adjust and switch the working mode according to the water depth and flow velocity, and the working frequency is obtained.
The best accuracy of flow measurement is obtained.
(5) It has the function of layered velocity measurement, which supports the measurement of "velocity", "flow rate" and "flow direction" at the designated depth end.
