Tipping bucket rain gauges

Tipping bucket rain gauges is a kind of hydrological and meteorological instrument, which is an important rainfall observation instrument, it is mainly used for real-time observation and recording of rainfall data, and output these data in digital form. The following is a detailed introduction about tipping bucket rain gauge:

Working principle of tipping bucket rain gauges

The working principle of tipping bucket rain gauge is based on the movement principle of tipping bucket. When rain falls on the tipping bucket, the bucket will turn over at a certain angle, which triggers the sensor to record the time and amount of the next rainfall. The tipping bucket usually consists of two or more buckets. When the rainwater accumulates to a certain amount, the tipping bucket will turn over and empty the rainwater, and a counter will record the number of times the tipping bucket is turned over, thus calculating the amount of rainfall.

Core components and accuracy

Bucket: The bucket is the key component of the tipping bucket rain gauge, and its design and accuracy directly affect the accuracy of the measurement results. The resolution of the tipping bucket is usually 0.1mm, 0.2mm, 0.5mm, users can choose the appropriate resolution according to the actual needs.

0.2mm precision

The 0.2mm accuracy tipping bucket rain gauge can provide finer rainfall data, which is suitable for application scenarios that are sensitive to precipitation changes, such as meteorological research, precision agricultural irrigation and so on. This high accuracy device can capture small changes in precipitation and provide researchers with more accurate precipitation data.

0.5mm Accuracy

The 0.5mm accuracy tipping bucket rain gauge is suitable for general meteorological observations and hydrological monitoring. It can meet most precipitation measurement needs while maintaining a high cost performance. In flood control, water supply scheduling, power station reservoir water management, etc., 0.5mm accuracy tipping bucket rain gauge can provide reliable data support to help decision makers make scientific and reasonable scheduling plan.

Material Selection

The material of tipping bucket rain gauge is mainly divided into stainless steel and ABS two kinds.

1. Stainless steel

Stainless steel tipping bucket rain gauge has high corrosion and abrasion resistance, suitable for a variety of harsh environments. Stainless steel rain gauge has a long service life and stable performance, suitable for long-term observation.

2. ABS material

ABS tipping bucket rain gauge is light weight, easy to install, and has good weather resistance, ABS material rain gauge is suitable for temporary observation or the weight and installation of more stringent requirements of the occasion.

Features and advantages of tipping bucket rain gauge

1. High precision: the tipping bucket rain gauge can accurately measure the rainfall, with a small error range, to meet the needs of various meteorological and hydrological observations.

2. High degree of automation: the equipment can automatically record rainfall data and transmit it to the data centre through wired or wireless means to achieve remote monitoring and management.

3. Strong anti-interference ability: the circuit design of the tipping bucket rain gauge has anti-interference ability, which can effectively avoid the influence of external interference on the measurement results.

4. Easy to install and maintain: the equipment has a simple structure, easy to install, and low maintenance costs, suitable for use in a variety of environments.

5. Wide range of application: the tipping bucket rain gauge is suitable for meteorological stations (stations), hydrological stations, agriculture, forestry, national defence and other relevant departments to be used for the remote measurement of liquid precipitation, precipitation intensity, precipitation start and end time.

Application Scenario and Role of Hopper Type Rain Gauge

Tipping bucket rain gauge is widely used in meteorological observation station, hydrological station, agricultural irrigation, environmental protection monitoring and water conservancy engineering and water resources management and other fields. Especially in the automatic hydrological measurement system for the purpose of flood control, water supply scheduling, water management of power station reservoirs, etc., the tipping bucket rain gauge plays a vital role.

1. Meteorological observation: as one of the important equipments in meteorological observation station, it is used to record rainfall data in real time and provide accurate data support for meteorological forecasting and hydrological monitoring.

2. Hydrological research: In the field of hydrology, tipping bucket rain gauge is used to monitor and record the rainfall in a specific area, which helps to reveal the spatial and temporal distribution law of rainfall.

3. Agricultural irrigation: Accurate rainfall data is crucial for agricultural irrigation management, and the data from tipping bucket rain gauges can help farmers rationally adjust their irrigation schedules to ensure that their crops are supplied with enough water to avoid wasting water or under-irrigation.

4. Water resource management and flood prevention: Through real-time monitoring of rainfall, we can understand the flood situation and water resource situation in a timely manner, and provide scientific basis for flood prevention and mitigation and water resource management.

5.Flood prevention and early warning

The tipping bucket rain gauge can monitor real-time rainfall and provide accurate data for flood prevention and early warning. Before the flood, through the monitoring of precipitation, it can provide strong support for the formulation and implementation of flood control measures.

6. Water Supply Dispatch

Tipping bucket rain gauge can be used to monitor the precipitation of the water source, providing accurate data for water supply scheduling. According to the size of the precipitation, the water supply can be reasonably adjusted to ensure that the water supply demand is met.

7. Power station reservoir water management

Tipping bucket rain gauge can be used for water management of power station reservoirs, real-time monitoring of precipitation, for reservoir storage and release decision-making basis. Through accurate precipitation data, the operation of power station reservoirs can be optimised to improve power generation efficiency.

Summary

Tipping bucket rain gauge is a kind of precipitation observation equipment with high reliability and stable accuracy plays an important role in many fields, such as meteorological observation, hydrological research, agricultural irrigation, environmental protection monitoring, as well as water conservancy engineering and water resources management. There are two materials of stainless steel and ABS for choice, users can choose the right rain gauge according to the actual needs.

Through real-time monitoring of rainfall, tipping bucket rain gauge plays an important role in flood prevention and early warning, water supply scheduling, power station and reservoir water management and other scenarios, which provides strong support for hydrological automatic measuring and reporting system and automatic field measuring and reporting station, and promotes the scientific development and technological progress in related fields.
