Summary: This instrument is a primary instrument for precipitation measurement, and its performance conforms to the national standard GB/ t11832-2002 "tipping bucket rain gauge" and the national standard GB/ t11831-2002 "telemetry rain gauge for hydrological measuring and reporting device" related requirements. The core component of this instrument is the tipper, which adopts the three-dimensional streamline design, so that the tipper can turn over water more smoothly, and has the function of self-cleaning dust and easy cleaning. Structure and features: The tipper of this instrument is designed in a three-dimensional streamline, and has a drooping arc point of flow guide. Its shape is beautiful and smooth, with better water-turning performance and easy cleaning and maintenance. The water diversion funnel of the instrument is installed in close coordination with the tilting bracket, and it is generally unnecessary to remove the water diversion funnel. The water diversion funnel, tumbler and drainage funnel of this instrument are made of imported high-quality transparent materials, so that the dynamic working process of the instrument can be observed more clearly. This instrument is equipped with two permanent magnetic steel on the skip, and two dry reed tubes on the dry reed tube bracket. When the instrument leaves the factory, the magnetic steel and the dry reed tubes have been adjusted at an appropriate coupling distance, so that the output signal of the instrument has a certain proportion to the number of flips of the skip. One of the two signal outputs of the instrument is used for field counting and metering, and the other one is used for telemetry message. When the instrument is connected with the telemetry terminal, it shall be equipped with a matching interface circuit to prevent the counting and signaling errors caused by the shaking of the dry spring pipe and the skip back. This instrument factory has will skip Angle adjustment screw locking in the best position and Angle of screw Angle bp some red paint paint processing, only when the user installation instrument will skip in accordance with the requirements of this manual will be installed on the bracket of skip skip two shaft sleeve will skip stents and make level in the bubble in the center position can be put into use, need not to adjust the tilt Angle at the scene. Main technical parameters: 1. Diameter of bearing rain: φ 20000.60 mm, acute angle of cutting edge: 40 °~ 45 ° 2.Resolution: 0.5mm; 3. Measurement accuracy: less than or equal to 3% (artificial indoor precipitation, subject to the displacement of the instrument) 4. Rain intensity range: 0.01mm ~ 4mm/min (maximum rain intensity of 10mm/min is allowed) 5. Output signal: single dry yellow tongue tube on and off 6. Working environment: Ambient temperature: - 10 ~ 50 ℃ Relative humidity;< 95% (40 ℃) 7. Reliability: under the condition of normal maintenance of the instrument, the average trouble-free working time MTBF is more than 16,000 hours 8. Size and weight: 3kg.
Summary: This instrument is a primary instrument for precipitation measurement, and its performance conforms to the national standard GB/ t11832-2002 "tipping bucket rain gauge" and the national standard GB/ t11831-2002 "telemetry rain gauge for hydrological measuring and reporting device" related requirements.
