Summary:
This instrument is a multi-layer bucket volume sensor, 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 two invention patents (patent no. :ZL201010112118.5). (201310294147.1) : two-way plate turning device and cascade controlled release funnel for smoothing rain intensity are installed above the metering hopper, effectively improving 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. After adopting the above two technologies, the systematic error of the instrument can be reduced to the leading level of less than or equal to 1%, and its performance is more stable and reliable, and the method of on-site verification of instrument error is simpler;
2. The machine core support of the instrument is a metal casting integrated support, which has the advantages of good disassembly repeatability and good stability;
3. The tipper capacity positioning adjustment screw of this instrument is designed as "tooth fine thread", and the tipper capacity adjustment is more precise;
4. Two permanent magnets are set on the counting hopper of the instrument and two corresponding dry reed tubes are configured to make the signal transmission of the instrument more reliable. Main technical parameters:
1. Diameter of bearing rain: φ 20000.60 mm; acute angle of cutting edge: 40 ~ 45 °
2.Resolution: 0.1mm
3. Rain-intensity range: 0.01mm ~ 4mm/min (maximum rain-intensity of 8mm/min is allowed)
4. measurement error:
≤ ±4% (in accordance with the national standard III accuracy requirement)
≤ ±3% (conforms to the national standard II class accuracy requirement)
≤ ±2% (conforms to the national standard I accuracy requirement) )
≤ ±1% (accuracy is higher than the National Grade I Standard)
5. Signaling mode: two ways of dry spring pipe on and off signal output
6. Work environment: the environment temperature: - 10 ℃ to 50 ℃
Relative humidity: < 95% (40 ℃)
7.Size, weight: φ 216mm × 470mm; weight: 3.8Kg
