From May 16th to 19th, 2012, Shenzhen Qipu Optoelectronics Co., Ltd. was invited to participate in the 2012 Russian International Professional Lighting, Entertainment and Entertainment Technology and Service Exhibition.
Piezoelectric ceramic disc
Quick delivery
High performance
Application: flow meter measurement
There are many kinds of USF used in closed pipeline according to the measuring principle, and the most commonly used are propagation time method and Doppler method. Among them, time difference ultrasonic flowmeter is used to measure fluid flow by the principle that the time difference of sound wave propagating downstream and countercurrent is proportional to the velocity of fluid flow. It is widely used in raw water measurement of rivers, rivers and reservoirs, process flow detection of petrochemical products, water consumption measurement of production process and other fields. According to practical application, time-difference ultrasonic flowmeter can be divided into portable time-difference ultrasonic flowmeter, fixed time-difference ultrasonic flowmeter and time-difference gas ultrasonic flowmeter.
Ultrasonic flow-meters use at least two transducers aligned so that ultrasonic pulses travel across the flow of liquid or gas in a pipe at a known angle to the flow.

In the same kind of exhibition, the scale of this exhibition has ranked second in the world. The exhibition hall of the exhibition includes 6 lighting and sound museums, 2 musical instruments halls and 4 tent-style temporary exhibition halls. More than 1,700 exhibitors from more than 20 countries and regions show more than 10,000 kinds of exhibits. The organizers took advantage of the trend and moved the exhibition to the new exhibition hall of the National Exhibition. In one fell swoop, the exhibition area of ​​the exhibition exceeded 110,000 square meters, an increase of nearly 30,000 square meters. 
Qipu Optoelectronics carried four P10 white shark cast aluminum boxes, P16 hollow screen modules, P21.33 hollow screen modules and P16 dual maintenance modules to participate in the exhibition. It is worth mentioning that the large white shark cast aluminum box was sold on the spot and won a full house applause. 
Russian exhibition of the Great White Shark
The Great White Shark cast aluminum case takes accuracy to a new level. Ordinary iron boxes, the general error will be less than 1mm, and the large white shark cast aluminum box developed by Qipu Optoelectronics, the error can be as low as 0.2mm, greatly reducing the error.
The ultra-thin cast aluminum box of the great white shark has a unique appearance and light disassembly and assembly, and is unique among similar products, mainly suitable for rental and lifting occasions. Its main features are as follows:
1. Due to the use of cast aluminum material, it has advantages in weight and the cabinet is light.
2. The strength of the box body is high. The die-cast aluminum box body has a high-pressure one-time forming die, and the strength is higher than that of the sheet metal bending aluminum box.
3, the appearance is beautiful, because the die-cast aluminum box is molded at one time, the appearance is exquisite, and the dimensional accuracy is high.
4. The flatness is high, the die-casting aluminum body is formed by the mold, the size of the box is strictly controlled, and the flatness is very good, which can effectively reduce the seam of the box body.
5. Die-casting aluminum box has high die-casting efficiency, which can basically realize mechanized operation and greatly shorten the production cycle.
Hollow screen of the Russian exhibition
The hollow screen series products are mainly used in outdoor roof and column advertising screens, suitable for making large-area display screens. The main models are P12.5, P16, P21.33, P25.6, P32 and so on. Its characteristics are as follows:
1. Transparent design does not affect the ventilation and lighting at the rear of the screen. The wind resistance is small, the weight is light, and the weight is less than half of the conventional display.
2, modular design, easy to install and maintain. The driver chip is placed on the lamp surface for easy maintenance. All modules are designed in a unified manner, and the production and stocking are the same modules.
3. The front side of the module is filled with glue to solve the heat dissipation problem in the form of air convection heat dissipation.
4, high light transmittance, can reach 40%, uniform light transmission.
Russian maintenance double maintenance articles
P16 double-sided maintenance full-color screen has created a precedent for front and rear display maintenance, and is another great innovation of Qipu Optoelectronics following the series of “Black King Kongâ€, “Great White Shark†and “Blend Screenâ€.
Advantages of P16 double-sided maintenance full color screen:
1, can be maintained before and after, greatly saving maintenance costs, making maintenance easier.
2. There is no screw between the module and the box. It is more convenient to disassemble and disassemble. It can be removed in a few seconds, and the work efficiency is greatly improved.
3, the cabinet is light and thin, the maximum thickness is 115mm, the weight is 26kg, compared with similar products, it is much thinner.
4, save space, the traditional display must leave enough space for post-maintenance, and now, the space is greatly saved.
5. Later, it will continue to develop more models of double-sided maintenance display such as P13.33, P20, P26.66, etc., so that customers have more choices.
Conclusion
At this moment, 2012 Russia International Professional Lighting, Entertainment and Technology and Service Exhibition has come to a successful conclusion, but the shock and moving of Qipu Optoelectronics to the world has been delayed, she relies on her own strength and innovation. The ability to return home. Here, we look forward to the surprise and touch of Qipu Optoelectronics in the next Russian exhibition. At the same time, we also wish Qipu Optoelectronics, I hope she will go further and further on the road of LED, more and more brilliant!
