摘  要：
The application of ultrasonic flowmeter is an important way to solve the question of quota and ration of irrigation water.【Objective】Analyse the classification and characteristics of ultrasonic flowmeter, elaborate the problems of the domestic and foreign present research situation of ultrasonic flowmeter in this paper, and put forward the development trend in the future.【Method】Acoording to the review of conferences, we summed up the research on flow pattern and structure optimization of ultrasonic flowmeter in irrigation area mainly concentrating on the influence of different physical model structure design on flow field distribution, the arrangement of probe and the optimization of vocal tract shown by the variation of the parameters of the channel, the number of channels, the distance between the inlet, the new method and the new material research of the probe in the development of digital information, precise intelligence, integrated control and equipment system and the design of high sensitivity and small signal attenuation probe, and the hardware and its algorithm focued on the algorithm and its circuit system improvement. The correction was derived from the liquid temperature, acoustic refraction signal attenuation, circuit reaction time delay.【Result】Foreign developed countries developed the ultrasonic control integrated system applied to the irrigation area, and established a scientific and standardized irrigation water allocation management system and norms.【Conclusion】In future, China should focus on the establishment of design specification of water irrigation equipment,research and development of quantity control integrated device and its supporting equipment, scientific management system of water resources allocation in multidimensional space, accurate decision calculation method to adapt to the wisdom of water at this stage in different regions and conditions.
