Gravimetric Rain Buckets
1. Measure real-time barrel weight
2. Measure real-time precipitation intensity
3. Minute precipitation analysis
4. Cumulative precipitation data storage, etc
The 1500 Precipitation Monitor uses the load measurement principle to monitor all types of precipitation in solid, liquid and mixed solid-liquid states. Through high-precision sensors, a stable balancing system, and customized detection algorithms, the instrument can accurately measure real-time barrel weight, precipitation intensity, calculate cumulative precipitation, and more. The instrument can be connected to the cloud, providing customers with accurate, real-time and convenient precipitation data.
The instrument is equipped with a 1500mm capacity bucket and a stable mechanical structure, which has the characteristics of simple and convenient installation, maintenance and calibration. This instrument organizes production, assembly and verification in strict accordance with the requirements of SL 21-2006 Precipitation Observation Specification and SL/T811.4-2021 "Precipitation Observation Instruments Part 4: Gravimetric Rain Gauges". It serves meteorological stations (stations), hydrological stations, transportation, agriculture and forestry, electric power, national defense, ocean, scientific research and other fields, and can cope with extreme weather phenomena such as blizzards, heavy rains, and droughts.
