Ultrasonic rain gauge, ultrasonic digital rain gauge, ultrasonic rain sensor Tracy: Mil Albert - DONG, Overview Ultrasonic rain gauge is based on the principle of ultrasonic ranging high-precision rain gauge data stability, high accuracy, precision up to 0.1mm, meteorological, hydrological forecasting system to achieve the ideal equipment for automatic rainfall telemetry. The product consists of rainwater harvesting, rain gauge, measurement subsystem, cleaning subsystems. Weather resistant material shell, with high strength, corrosion resistance and other characteristics, can be installed directly in the wild. Ultra-low-power design, the quiescent current of only 1.5mA in the wild environment, the available solar and battery powered. The measurement time is short, a measurement can be completed within 2 seconds, measuring frequency of up to once per minute, and enhance real-time data. The whole rain gauge no mechanical transmission components, an increase of the life of the rain gauge, a lot of drive, high-precision, anti-harsh environment requirements. Second, the principle of the working principle of ultrasonic distance measurement of ultrasonic rain gauge measured and stored each time the fluid level in the rain gauge, every one minute measurement time. Twice the measurement time interval of one minute, rain gauge maximum acquisition frequency of once per minute. Rain gauge can be configured to take the initiative to report the way passive reported, the initiative to report to report the frequency can be configured from one minute to 24 hours. Set of rain gauges according to national standards diameter 200mm, rain gauge diameter of 200 mm, the difference in level of the rain gauge is in fact a rainfall. Ultrasonic rain gauge main parameters the name parameter rainwater harvesting diameter 200MM rainfall inner diameter 200MM height 0.94M input power supply 9-18VDC-state current 1.5mA maximum operating current of 150mA signal output RS-485 collection frequency of once per minute without loss of maximum rainfall concept of measurement is continuous rainfall Accuracy 0.1MM 500MM ambient temperature 0 ° C to 70 ° C Environment humidity 0 to 100%
