1 Overview
The instrument for measuring precipitation of an instrument, its performance conforms to the national standard GB/T11832-2002 "tipping bucket" requirements.
The key component of the instrument is a three dimensional streamlined design, which makes the bucket turn over water more smoothly, and has the function of self cleaning dust and easy cleaning.

2 structure and characteristics
The instrument consists of a rain mouth, a filter screen, a water funnel, a tipping bucket assembly, a tipping bucket support, a tilt adjustment device, a reed switch, a signal output terminal, a base, a base supporting foot, and a stainless steel cylinder body, etc..
The bucket support of the instrument is an integrated rotary positioning structure, so that the tipping bucket is more convenient to install and dismantle.
The turning bucket of the instrument is a three dimensional streamline design, and the design has a drop type cambered surface diversion tip, which has beautiful appearance, smooth flow, better water turnover performance and easy cleaning and maintenance.
Two reed switches are installed on the dry reed pipe of the instrument, one of the two signal outputs is used as the spot count, and the other is used as telemetry message.
This instrument has been factory bucket angle adjustment screw to lock in the best position and angle of inclination of point screw made red paint seal treatment, users only need to adjust the instrument installation of anchor supporting feet raised the height of the nut so that the level of bubble is located in the center position can be put into use, does not need to re adjust the dump site dip.
