This instrument meets People's Republic of water conservancy and hydropower industry standard SL21-1990 "precipitation observing practices," "long-term self-recording type rain gauge"
Sense of rain this instrument sensitivity, accuracy, scope of rainfall intensity gauges are better than other forms, suitable equipmenta, northern environmental conditions of various types of dust rainfall stations.
Features
● sense of rain with high sensitivity (0.07mm).
● high accuracy.
● equipment installation, adjustment, calibration method is simple,
● high intelligence, easy maintenance.
● There Pulse (per 0.1mm rainfall) output and RS-485 real-time rainfall total output can be directly with data acquisition, RTU, computer or other host devices, high precision automatic data acquisition and transmission.
Use of 3
Technical performance of this instrument is much higher than the international and domestic current rain sensor, suitable for equipment parts, under different climatic conditions, the state's basic rainfall stations, encryption automatic weather (rainfall stations) and telemetry stations, auto-complete the precipitation process measurement and data collection, especially for an alternative to traditional paper record siphon rain gauge, make existing siphon rainfall station unattended and automated data integration, automatic transmission.
