Digital gauge

1 uses
This instrument complies with People''s Republic of China water conservancy and hydropower industry standard SL21-1990 "precipitation observation standard" "type pluviometer long-term recording and China Meteorological Bureau in 2003 edition of" standard "in the" meteorological automatic rainfall station "of the relevant requirements.
The rain sensitivity, measurement accuracy, rain intensity scope are better than other forms of rain gauge, equipment in China for heavy rainfall area, South North dust environmental conditions of the various types of rainfall stations.

2 characteristics
The sensitivity of rain is high (0.07mm).
Accuracy is high.
Instrument installation, adjustment, calibration method is simple,
It has high intelligence and convenient maintenance.
There is pulse output (0.1mm per rainfall) output and RS-485 real-time cumulative rainfall output, which can be directly connected with data acquisition device, RTU, computer or other upper equipment to achieve high-precision data automatic acquisition and transmission.

3 scope of use
The technical performance of the instrument is far higher than the international and domestic existing equipment for rain sensor, all localities and different climate conditions of the national basic rainfall stations, intensive automatic weather (rainfall) and telemetry station, automatic measurement and data acquisition of precipitation, which is used to replace the traditional paper record type siphon gauge. The siphon rainfall station unattended and automatic data processing, automatic transmission.
