Artificial flow measurement is characterized by low efficiency,poor timeliness,high risk and cost. So,the development of unmanned automatic flow measurement is quite necessary. Based on theory of automatic control,an automatic flow measurement system is developed. The system employs non-contact radar wave velocity meter as the surface velocity measurement sensor,uses the simple double-track cable to move the radar wave flow measurement meter to the above of the flow measuring position for measuring the surface flow velocity. At the same time,the system can collect real-time water level data to realize automatic monitoring the level and flow. The system can automatically control the whole process of flow measurement,with strong error control ability and good auxiliary management ability,which solves the problem of automatic flow measurement of small and medium-sized rivers and rivers of sharply flow rising and falling in mountainous areas.
