This standard applies to siphon and tipping bucket rain gauge precipitation from digitized paper records and record storage management products, applications.2 Terms and definitionsThe following terms and definitions apply to this document. 2.1 Gauges raingauge Precipitation measuring instruments, mainly by bearing water heaters, storage water bottle, cylinder components. [QX/T 8-2002, the definition 5.5.20] 2.2 Rain Gauge pluviograph Automatic recording instrument precipitation changes over time. [QX/T 8-2002, the definition 5.5.13] Note. The commonly used siphon rain gauge tipping bucket rain gauge and two kinds. 2.3 Self-recording rainfall paper precipitationrecordingpaper For automatic recording rain gauge rainfall varies with time dedicated paper. 2.4 Rainfall trace precipitationrecordtrace Precipitation records from paper record precipitation versus time trajectory. NOTE. Siphon rain gauge precipitation traces are straight lines and curves, tipping bucket rain gauge precipitation trace straight lines and polylines. 2.5 After precipitation from note paper to form a digital image file by scanning or digital photography, automatic extraction of information and statistics precipitation changes over time Get precipitation process unit time and other relevant information.3 ProcessWhen the self-recording rainfall recorder digitized main processes include self-recording rainfall paper preprocessing, image input, precipitation information extraction, obtaining unit Between precipitation and other four steps, specific process shown in Figure 1. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 31165-2014_English be delivered?Answer: Upon your order, we will start to translate GB/T 31165-2014_English as soon as possible, and keep you informed of the progress.
