3 the signal missing 3, data acquisition stabilizer circuit parameters function failure 4, objective 4, compared with rain gauge measurement system with rain sensor farther apart or reasons, non-instrument malfunction strong winds Rainfall Check whether the outlet is Water treatment continued to flooding, especially after and re-install count, but the heavy rain reality did not rain Note: Symptom listed in the table is not necessarily the fault of their own rain gauge, after checking the instrument itself should also check for troubleshooting instrument qualifying transmission, data acquisition devices, telemetry terminals and other equipment is faulty, and excluded one by one to solve. Accuracy calibration Emergency Measures (customer self) 1, test tools: dedicated rainfall cylinder 1, a small dropper; 2, before the test to check: Before the test, first remove the stainless steel outer tube inspection equipment level bubble is centered, whether the flip dump flexible, cable wiring and check the water is smooth, then use the water to water funnel, Tipper fully wet; 3, water test Drip method using two-speed test equipment measurement accuracy, the method is as follows: Take water with a special cylinder rainfall amounts of 10mm, to funnel water through arbitrary rain intensity between 0 ~ 4mm of rain intensity slowly into the water on the dump bucket, until the next dump the last bucket not want to turn, that stop the water and then with a dropper quantitative measure of water, drop by drop added to the dump until the next dump flip stops dripping, followed by trial and error, dump record number of turns and water consumption. 0.2mm dump flipped 50 times, the consumption of water is 9.80 ~ 9.90mm, the instrument can be found tipping point angle normal, do not have to be adjusted; when poured water> 9.90mm, described Tipper tilt angle is too large, should increase the height adjustment screw; when pour water <9.80mm, described Tipper tilt angle is too small, should be appropriately reduced height adjustment screw; generally speaking, the adjustment screw revolution, to make precision changes from 2 to 3%. NOTE: This method only as a site emergency instrument calibration error with. Accurate calibration of the instrument error must be in accordance with national standards GB / T "tipping bucket rain gauge" requirements in rainfall intensity calibration or test rig will return to the factory calibration of the instrument. Rainfall output signal corresponding to the formula Switch count * 0.2mm = rainfall Eight, rainfall level Description The classification of rainfall, different departments have different standards. Meteorological Department: rainfall in a certain time fall into the water depth of the ground, expressed in millimeters. Said unit time rainfall intensity. Rain with rainfall intensity level to be divided as follows: Rainfall level 12 hours rainfall 24 hours rainfall ight rain 0.1~ ~9.9 Small to moderate rain 3.0~ ~16.9 Moderate rain 5.0~ ~24.9 Moderate to heavy rain 10.0~ ~37.9 Heavy rain 15.0~ ~49.9 Heavy rain 30.0~ ~74.9 Rainstorm 30.0~ ~99.9 Heavy rain storm 50.0~ ~174.9 Heavy Rain 70.0~ ~250.0 Heavy rain to rainstorm 105.0~ ~300.0 Rainstorm >140.0 >250.0 Flood control departments: a little water to a depth of rainfall per unit area is within a certain time landing on the ground or in millimeters. According to the National Civil Air Defense Office "Flood Control Handbook", where the 24-hour accumulated rainfall over 50 mm were defined as heavy rain. 12-hour and 24-hour rainfall intensity rainfall intensity rainfall size division level, as follows: Strong rain evel 12 hours rainfall 24 hours rainfall ight rain R12<5 R12<10 Moderate rain 5 R12<10 10 R12<25 Heavy rain 10 R12<30 25 R12<50 Rainstorm 30 R12<70 50 R12<100 Heavy Rain 70 R12< R12<200 Rainstorm 140 R R12 Hydrological Department: Generally speaking, rain, rain, rain, rain, etc., generally daily rainfall measured. ight rain to happen where rainfall of 10 mm or less; moderate daily rainfall of 10 to 24.9 mm; heavy rainfall of 25 to 49.9 mm; storm rainfall of 50 to 99.9 mm; September, 2016 Rev. 2 3 SZ7001

4 heavy rain rainfall of 100 to mm; King storm rainfall of 200 mm. In addition, people can also be determined from precipitation in rain levels: the next rain, rain generally legible, no floating phenomenon; fall to the ground, not on stone or tiles scattered; ground muddy shallow depression formed very slowly; at least more than two minutes before wet slate, tiles; only under the eaves dripping. Down in the rain, the rain, such as lines, raindrops are not easily distinguishable; landed hard on the roof tiles scattered rain; puddle puddles formed quickly; roof rustle. And when it rains, as rain poured down, blurred into pieces; landed on the roof tiles, stone or concrete can splash, pools formed quickly; there is the noise of the rain roof.
