Abstract
Now tipping bucket raingauge which is used in hydrology automatic system at home and abroad has the problem of sensor measuring error large. The sensor’s main errors are maximum starting, tipping bucket measurement, mouth size. Based on analyzing error causes, the article provides corresponding measures to improvement. The major measures are: adjusting tipping bucket sense accuracy, reducing tipping bucket angle, shorting changeover time of 2 buckets, increasing the area of the bearing mouth, installing the valve device to reduce error, spray coating Teflon on instrument surface, using software to correct error. It solves the problem of tipping bucket raingauge’s big error in theory. The tipping bucket raingauge can be extensive application in practice.关键词
