In meteorology, rainfall refers to the depth of rain falling on a horizontal surface (no leakage, evaporation, loss, etc.) within a certain period of time. Determined with a rain gauge. In millimeters. Meteorological stations measure every 6 hours in the presence of precipitation. We generally choose a rainfall recorder to measure rainfall, so why should we choose this instrument? First of all, to understand the use of rain recorders.
1. Open the computer and insert the supplied CD into the CD drive installation recorder application software.
2. Connect the sensor and recorder.
3. Connect the recorder to the computer's serial port with a communications cable.
4. Run the recorder's application software on the computer, start the recorder, set the recorder's record start time, record period, stop time, stop mode and other parameters. Select the normal mode/power saving mode according to the interval you set. It is recommended to use the power saving mode.
5. After the setting is completed, disconnect the recorder from the computer, place the recorder on the occasion to be detected, and the recorder will start recording automatically.
6. After the test is completed, connect the recorder to the computer and run the recorder application software to download the recorded data to the computer for data processing.

Rainfall recorder can store electronic records, can record rainfall start and end time, rainfall, PH value, conductivity, etc. It can save minute sampling data, hour sampling data, and the average data of the whole rain. It has a communication interface and can be connected to a computer. The advantages of Rainfall Recorder are also reflected in:
1, small size, simple operation, reliable performance, tracking rain data throughout the recording, long record time.
2. Recorded rainfall data cannot be modified, and it can provide the most original rainfall data in hydrological stations, environmental protection, agriculture, forestry and other departments.
3, powerful software, data viewing convenience.
4. You can connect to a computer and connect each downloaded data curve to a complete curve.
5, test time: ≤ 2 seconds.
6, recorder AC and DC dual-use, you can get the field to collect data anytime, anywhere, but also can be placed for a long time to record location for collection.

Flexible Gate

Flexible lift gate is a flexibel soft curtain door, inside and outside the two curtains , curtains used between the aluminum beams connected with a vertically movable rail , the roof beams have levels not in the same straight line and hanger large plants in particular Be applicable , Flexible lift door installation does not take up interior space in the hole inside , When the first move to open the door , and finally superimposed over the hole , Off event curtain rail first and then fall down until its is completely closed

Door body composition :

The bottom of the door curtain rail aluminum beam beam seal top drive system and transmission of electrical control systems and safety devices

Flexible door features:

1. Light weight compared with other types of the same size door , flexible door lighter weight reduces the strength of steel at the top of the doorway architecture degree requirements ,

2. Small compared with the same specification of the machine style doors 2, footprint ,flexible installation in the door after the hole is turned on internally stacked above the hole , do not take up interior space , Large Span hole may be provided a plurality of movable rail the entire door into several independent stacking doors shorten the span of a single door so that the overall thickness of the door is reduced , further reducing the footprint

3. Rational layout flexible doors with movable rail rail can set different activities based on the specific circumstances of the door into the door several sizes of uneven accumulation of doors to make the building as a whole rational layout greatly reduces the overall architecture of the space and cost

4. The wind strength between two layers of high flexible door curtain as the bottom of an aluminum beam has a wind skeleton steel structure , By adjusting the beam thickness and spacing , which can resist wind pressure of any intensity , so the door can be flexible for use in any area

5. The tensile strength of the flexible door after door curtain is double polyester fabric , high tensile wire rope equipped with ultra-high hole suitable for large machinery such as aircraft hangars and repository

6. The curtain coated with vinyl coated with a waterproof sunscreen and smoldering performance , capable of sound absorption retardant insulation mildew proof and so on

7. Safe door , Cube with anti-lock break to ensure safety in case of accidental breakage of wire rope jammed in the door quickly experience anywhere rails , Multiple protection features mechanical and electrical installation to ensure t he safety of goods passing aircraft and other vehicles and personnel , the movable rail is also equipped with anti-fall device , you can ensure reliable parked at the top of the hole after the movable rail is raised without falling , The bottom of the door is equipped with and airbag , it will immediately rebound to rise until the safety door drops open when obstacles encountered in the process , You can also install infrared protection device on the door
