Accuracy analysis of open channel river flow multi-beam monitoring system

With the global population expansion and rapid economic development, water resources have become the focus of attention, but there are no high precision and exist higher costs problem in domestic monitoring of open channel flow of river water in a long time. This research mainly studied beam of ultrasound sonar river section scanning technology, and applied to independent research and development of the water flow monitoring system, which provided an effective solution to the high cost and monitoring accuracy problem, furthermore, make the practical application of specific analysis of measured values of accuracy and proposed improvement program, it further enhance the monitoring sections of water flow measurement system reliability.
