Double Tipping Bucket Rain Gauge: Accurate Measurement of Rainfall

INTRODUCTION

As an important meteorological observation instrument, rain gauge plays an irreplaceable role in agricultural production, urban planning, water conservancy engineering and other fields. Accurate rainfall data helps us to prevent and respond to meteorological disasters scientifically, optimize water resource management and improve agricultural production efficiency.

Working principle of double tipping bucket rain gauge

Take the double-dipper rain gauge as an example, it consists of two layers, the upper layer is the transition hopper, and the lower layer is the measuring hopper. When the precipitation reaches a certain amount, the transition hopper is turned over, and the precipitation is introduced into the measuring hopper. The throttle tube is used to control the flow rate (i.e., rain intensity) of the rainwater so that the precipitation can be continuously injected until the metering hopper turns over and outputs a pulse signal. This signal is transmitted to the collector and used to record the amount of precipitation.

I. Advantages of double tipping bucket rain gauge

1, more accurate measurement data double dumpster rain gauge is a single dumpster rain gauge upgrade, due to the single dumpster rain gauge in the process of the dumpster overturned rain will continue to be injected into the dumpster, precipitation in the rainfall difference is large, which will bring error, in order to reduce the error, which will produce a double dumpster rain gauge. Double bucket rain gauge using plural buckets can be different intensity of natural precipitation intermittently and uniformly into the measuring bucket to improve the accuracy of precipitation detection.

2, the size of the inner diameter of the rain bearing mouth is 200mm, the rain bearing mouth edge is edge-like, the rain bearing mouth edge angle should be in the range of 40 ° ~ 45 °, to effectively ensure that the rainfall monitoring accuracy, support for 485 signals and pulse-type two types of signal output, with a resolution of 0.1mm, 0.2mm, 0.5mm three types of products. 

3、Double tipping bucket rain gauge as a tipping bucket rain gauge of the upper alternative, its use greatly improves the agricultural and industrial environment rainfall observation automation level.

Conclusion

Rain gauge is used to measure and record precipitation, is an important meteorological observation tool for agricultural production, urban planning, water conservancy projects and other fields. It can guide farmers to scientifically prevent meteorological disasters and strengthen drought-resistant irrigation work, so as to improve food production and quality and reduce disaster losses. The accurate observation of rain gauge is of great significance for agricultural production, urban planning, water conservancy projects and so on.
