What is the difference between a rain gauge and a rain gauge?
The rain is large or small. Sometimes the rain is very concentrated, causing rivers to overflow and the city to accumulate water; sometimes it is very small and cannot solve the drought. For this reason, timely monitoring of rainfall changes can provide accurate, true and timely reference for flood prevention and disaster prevention. There are two basic instruments for measuring precipitation: rain gauge and rain gauge.

Rain Gauge: It is an instrument used to measure the accumulated precipitation over a period of time. The shell of a common rain gauge is a metal cylinder, which is divided into upper and lower sections. The upper section is a water-containing funnel with a diameter of 20 cm. In order to prevent rainwater from splashing and maintain the area and shape of the container mouth, the mouth of the cylinder is made of hard copper. The blade is inclined outward; a water storage bottle is placed in the lower tube to collect rainwater. When measuring, pour rainwater into a special rain measuring cup and read the precipitation in millimeters. In the snowy season, take out the water storage bottle and replace it with a tube mouth without a funnel. The snowflakes can be directly collected in the rain gauge and read after the snow melts. The weight of the snow can also be converted into millimeters according to the area of u200bu200bthe tube mouth.

The rain gauge is divided into tipping bucket rain gauge and siphon rain gauge.

Tipping bucket rain gauge: It is a wired telemetry instrument that can continuously record precipitation changes over time and measure accumulated precipitation. It is divided into two parts: the sensor and the recorder, which are connected by a cable. The sensor is measured with a tipping bucket. It is two completely symmetrical triangular containers separated by a middle partition. The middle partition can rotate around a horizontal axis, so that the containers on both sides take turns to receive water. When one container is filled with a certain amount of rainwater (0.1 or 0.2mm), the water is turned over due to the shift of the center of gravity, and the water is poured out. As the rain continues, the tipping bucket will turn left and right. Read the precipitation data from the clock.

Siphon rain gauge: The siphon rain gauge is an instrument that can continuously record precipitation and precipitation time. The shape and size of the upper water funnel are the same as the rain gauge.

In modern times, with the blessing of the Internet, rainfall monitoring is more intelligent and convenient. At present, the tipping bucket rain gauge is more commonly used.

RS-YL tipping bucket rain gauge is a hydrological and meteorological instrument used to measure natural rainfall, and at the same time convert the rainfall into digital information output in the form of a switch, to meet the requirements of information transmission, processing, Record and display needs. It can be used in meteorological stations (stations), hydrological stations, agriculture and forestry, national defense, field observation stations and other related departments.

The three-dimensional streamlined design makes the tipping bucket rain gauge smoother, and has the functions of self-cleaning dust and easy cleaning. The drooping arc-surface guide tip has a beautiful and smooth appearance and better water-turning performance. . The inner diameter of the rain-bearing mouth is 200mm; the edge of the rain-bearing mouth is blade-shaped, and the blade angle is in the range of 40°~45°, which meets the national standard requirements of 'Tipping Bucket Rain Sensor' GB/T21978.2-2014, allowing entry The rain at the rain-bearing port does not splash outside the rain-bearing port, effectively ensuring the accuracy of rainfall monitoring; there are two types of products with a resolution of 0.2 and 0.5, and two signal outputs of 485 signal and pulse type are supported.

Features of tipping bucket rain gauge:

1. Reasonable structure design, beautiful appearance and corrosion resistance.

2. The measurement accuracy is high, the stability is good, the volume is small, and the installation is convenient.

3. Good linearity, long transmission distance and strong anti-interference ability.

4. The sensor housing is made of stainless steel, which has strong anti-rust ability and good appearance quality.

5. Stable and reliable work, and wear-resistant, long life.

6. There is a level adjustment bubble inside the chassis, which can be adjusted to the best level through the bottom angle.

In modern life, the rain gauge is the main instrument for monitoring rain, and it plays an important role in the meteorology, agriculture, water conservancy and other industries. After the evolution and development of the rain gauge, it has now The appearance and function.
