1 Overview
In recent years, the country vigorously into the project of flood disasters, rolling udometer gained a lot of popularity, but the determination of effective monitoring tool tipping bucket rain gauge accuracy is still blank, the design and manufacturing company in this case that a field monitoring and calibration gauge tool, it has two modes a, counter mode and calibration mode, the maximum can count to 9999999 in the timer mode, the calibration mode can be calculated amouth rainfall, rainfall duration, rainfall intensity and rainfall error, the instrument adopts the double bucket to ensure strong rain flow stability, simulated rainfall intensity can provide 4mm/min and 2mm/min, the instrument powered by a lithium battery, a charge can be used continuously for 8 hours, and the use of OLED LCD screen, even in the bright sun, also can clear Identification of liquid crystal clear display, the instrument has the advantages of small volume and easy to carry, suitable for Chengyu mouth diameter of 200mm automatic weather station, the new station and hydrological station maintenance, regular inspection, re enabled tipping bucket rainfall sensor calibration and test.
.
2 main technical parameters
2.1 control index of rain intensity:
Heavy rain (4mm/min) drip time: 10mm water once injected two level steady flow bucket, all the net drip time is: 2 ''30'' + 10''.
Moderate rain (2mm/min) drip time: 10mm water once injected double stable bucket, all the net drip time is: 5 ''00'' + 1''.
2.2 handheld display box
2.2.1 counting capacity: 0~9999999
2.2.2 clock accuracy: d/s
2.2.3 rate: 1Hz/ seconds
2.2.4 lithium battery capacity: 800mAh
2.2.5: = 8h time determination theory
2.2.5 outline size: 180 X 75 X 4 mm
2.3 working environment: ambient temperature: 4 ~ 35
Relative humidity: less than 90%RH, the wind speed is less than or equal to 6m/s
