Rainwater collected at the inlet of the water passes through the upper tube (funnel)，flow to the dose tipping bucket——Dumps are injection molded with engineering plastics with the middle partition into two equal-volume triangular chamber.It is a mechanical bistable structure, when a bucket room access to water, another bucket in a waiting state.
    When the volume of rainwater reaches a predetermined value of 0.2 (0.5) mm. Due to gravity to make their own overturned, in a waiting state, the other funnel is in the receiving water working condition.When the water reaches the predetermined value, their overturned, in a wait state.
    Magnetic steel is provided on the side wall of the tipping bucket，It with the dumping flip from the dry reed pipe next to the scan,so that dry reed pipe off. That is, every time the tipping bucket is overturned, the dry reed pipe is switched on and a switch signal (pulse signal) is sent.

A1: General type rainfall sensor (Tipping bucket rain gauge)
Funnel at the design of mesh, to prevent debris and other debris blocking the rain downstream;
Bucket parts support system manufacturing sophisticated, small friction torque, so flip flip parts sensitive, stable performance, reliable;
Bearing rainwater using the whole body made of stainless steel skin washed, high smoothness, stagnant water error is small;
The chassis is equipped with horizontal adjustment bubble inside, which can assist the bottom corner to adjust the equipment to the best level.

A2: Heated Rain Sensor (Heating rain gauge)
Additional temperature control switch, heating tube, temperature probe and other components, can be applied to low temperature freezing and low temperature snowfall measurement.

Special statement:
General type of rainfall sensor ABS material, stainless steel two,The heated rain sensor has only one stainless steel material.
General type of rainfall sensor is powered by solar panels，the heated rain sensor is powered by 220V AC.

B: Data acquisition transmitter

Data transmission using GPRS and short message compatible way;
With quantitative rainfall data sent alarm information function.

Data sampling frequency up to 1/min;
Unlimited cloud data transmission;
With battery voltage detection;
With automatic rain report function;
With remote set parameter function.

C：System platform

Dynamic real - time observation, high - precision map accurate positioning;
Unlimited cloud data storage, data synchronization update display;

Historical data image presentation, anytime, anywhere derived data;
Screen display size of independent settings, channel warning free set.

D: Solar battery + battery combination power supply

Solar powered:
The use of a wide range, without geographical, altitude and other factors;
The nearest power supply, to avoid long-distance transport power lines caused by the loss of power;
No mechanical transmission parts, there is no mechanical wear and tear, stable and reliable operation;
Do not use fuel, do not emit greenhouse gases and other emissions, environmental protection, pollution-free;
Solar panels fixed on the bracket, without a separate area, to avoid man-made damage;
Long service life and low maintenance cost.

Battery-powered:
During the day, there is sunlight, by the solar panels for battery charging;
Night, rainy days, by the battery for the operation of power supply equipment;
Combination of power supply to ensure continuous rain more than ten days of the case will not be power outages.

(Special declaration：Our monitoring stations in addition to the recommended use of solar panels + battery combination of power supply, but also support the city power 220V power supply, customers can choose according to their actual situation.)

E: Protection boxes and brackets

Stainless steel protective box surface by drawing process, can well protect the core part of the instrument, so that the host will not be wind, rain, sand and other interference, to ensure the normal work of equipment;

The bracket is made of stainless steel, with anti-corrosion and anti-rust, longer service life and more solid structure. It is divided into two sections，can be disassembled, transport convenience, use convenience.

Semi-circular cards, fixing screws and other components of the use of assembly, assembly more effort, solid and reliable, and interchangeable, easy to buy components.

The changes in rainfall data, all are within control.
Qing Yi Electronic rainfall monitoring station，worth your purchase.
