Abstract: The purpose of designing a new type of rain gauge is to solve the problem of easy blockage of the tipple-type rain gauge and ensure the high reliability of the equipment used in the matching automatic evaporation station. Benefiting from the experience of the original automatic evaporation station research project, the prototype of the intelligent anti-blocking magnetostrictive rain gauge was designed and manufactured, and was put into the observation field of the evaporation station for outdoor actual comparison experiments. The measured results show that the new magnetostrictive rain gauge designed can achieve the same rainfall monitoring results as the artificial ones. At the same time, the experiment found that the filter screen in the mouth of the rain gauge has a definite impact on the measured precipitation, which is also the main reason why most of the measured values of the tipple-type rain gauge are less than the manually observed rainfall values. The equipment is designed and positioned appropriately, but its function is not inferior to the expensive weighing rain gauge.
