Summary This instrument is a multi-layer bucket dosimeter, and its performance conforms to the national standard GB/ t11832-2002 "bucket rain gauge", and the China meteorological administration "guide to meteorological instruments and observation methods" (sixth edition) and related requirements. This instrument adopts the invention patent technology of cascade controlled release funnel (patent no. :ZL201310294147.1) : effectively improves the observation quality of precipitation data. The instrument is connected with data collector or computer, which can be used to accurately measure the starting and ending time of precipitation, cumulative precipitation and precipitation intensity of all kinds of weather stations, hydrological stations and rainfall observation stations. Performance characteristics Compared with other types of tipping bucket rain sensor, this sensor has the following advantages: 1. the performance of the instrument is accurate, stable and reliable. The system error can be reduced to the leading level of less than or equal to 1%, and the accuracy meets the requirements of the national first-class standard. 2. the equipment for on-site verification of instrument errors is simple, and the method is simple and practical; 3. the machine core support of the instrument is a metal casting integrated support, which has the advantages of good disassembly repeatability, good stability and so on; 4. the instrument has a high degree of moulding, and the factory inspection of the product has realized automatic computer detection with good product consistency. Main technical parameters 1.Diameter of bearing rain: φ 20000.60 mm, acute angle of cutting edge: 40 °~ 45 ° 2. Resolution: 0.2mm 3. Rain intensity range: 0.01mm ~ 4mm/min (maximum rain intensity allowed is 8mm/min) 4. Accuracy of measurement: ≤ ±2% (in accordance with National Standard I accuracy requirements) ≤±1% (accuracy is better than National Grade I Standard) 5 .Signaling mode: two ways of dry spring pipe on and off signal output 6. Working environment: Environment temperature: - 10 ℃ to 50 ℃ Relative humidity: < 95% (40 ℃) 7.Size: φ 216mm × 470mm
