Tipping bucket rain sensor

A tipping bucket rain sensor, also known as a tipping bucket rain gauge or tipping bucket rain gauge, is a hydrological and meteorological instrument used to measure natural rainfall. The working principle of the tipping bucket rain sensor is based on the mechanical tipping bucket measurement principle, which measures rainfall by collecting precipitation and displacing it mechanically. When precipitation enters the sensor, each tipping bucket is automatically turned over as the precipitation accumulates, and the counting device counts each time it is turned over. In this way, the amount of precipitation can be estimated by recording the number of times the tipping bucket is turned over.

The tipping bucket rainfall sensor is suitable for meteorological stations (stations), hydrological stations, agriculture, forestry, national defense and other related departments for remote measurement of liquid precipitation, precipitation intensity, precipitation start and end time, etc. It has the advantages of structure, accurate measurement, and high accuracy. It has the advantages of simple structure, accurate measurement, easy maintenance, etc., and has been widely used in many fields.

Principle of tipping bucket rain sensor

The principle of tipping bucket rain sensor is mainly based on the tipping of the bucket to measure the rainfall. The working process is as follows:

First, rainfall enters through the upper water funnel of the sensor, and when the rainwater accumulates to a certain amount, it will make the tipping bucket lose balance and flip. Each time the hopper flips, a switch is triggered, generating an electrical signal. This electrical signal is then recorded or transmitted for subsequent data processing and analysis.

In this way, the Tipping Bucket Rainfall Sensor is able to monitor rainfall in real time, continuously, and record changes in rainfall over time. Its design principle is simple yet effective, and it can accurately measure parameters such as rainfall intensity, precipitation amount, and the start and end time of precipitation.

The tipping bucket rain gauge is an important rainfall observation instrument that can digitize rainfall data in real time, which has the advantages of accurate time, automatic data recording and easy data collection and processing. 

Core components: tipping bucket 

Resolution: 0.1mm, 0.2mm, 0.5mm, 1mm optional 

Measured rainfall intensity range: 0.01mm ~ 4mm / min

It should be noted that the tipping bucket rain sensor may be sensitive to the size and shape of the raindrops, and therefore may have some error under extreme conditions. In addition, factors such as the sensor's mounting position and the size and shape of the tipping bucket need to be carefully considered and calibrated in order to ensure the accuracy of the measurement results.

Overall, the tipping bucket rainfall sensor is a reliable rainfall measurement device. The tipping bucket rainfall sensor has the advantages of simple structure, accurate measurement, easy maintenance, etc. It can measure rainfall in real time, help people understand the rainfall situation, and provide support for decision-making. It can provide people with real-time data about the rainfall situation, which is of great significance for the research and application in the fields of meteorology, hydrology and agriculture.
