Abstract

The invention relates to a detecting instrument of a rain gauge. The detecting instrument includes a water tank for holding simulated rainwater, a gravity detecting device for detecting the weight of the water tank and a control system. The water tank is used for communicating with the to-be-detected rain gauge. The control system is electrically connected to the gravity detecting device and the to-be-detected rain gauge. When the simulated rainwater flows from the water tank into the to-be-detected rain gauge, the to-be-detected rain gauge detects detection volume of the simulated rainwater and displays the detection volume on an interactive screen through the control system. The gravity detecting device detects a weight change of the water tank, calculates volume according to a changed weight value and the density of the simulated rainwater, and displays the calculation volume on the interactive screen through the control system. Since the technology of gravity measurement develops maturely, the measurement precision is high and the rain gauge usually detects a volume value, the determination of the precision of the rain gauge by detecting the weight can perform high-precision calibration on the rain gauge.

Description

technical field [0001] The invention relates to calibration and detection of a rain gauge, in particular to a calibration instrument for a rain gauge. Background technique [0002] A rain gauge is an instrument used for meteorological monitoring and hydrological monitoring to measure the amount of precipitation in a certain area over a period of time. The rain gauge can detect the volume value of rainwater and convert it to the corresponding mm value as an indicator of rainwater intensity. The common ones are siphon type, weighing type, tipping bucket type, etc. Meteorological sensors need to be inspected every year according to national regulations. At present, the peristaltic pump used in the fixed inspection device of rain gauges can only perform approximate detection of total rainfall, but cannot High-precision detection of different minute rain intensity. Contents of the invention [0003] The purpose of the present disclosure is to provide a calibrating instrument f...
