Qiqi Optoelectronics Shenzhen set up a subsidiary to speed up the layout of the mainland market

Optimistic about the good prospects of the LED lighting market in the Mainland, Qiqi Optoelectronics will set up a subsidiary in Baoan District, Shenzhen in late July to cope with the increasing demand for LED lighting orders in the Mainland, and cooperate with the lighting manufacturers in South China to provide the most instant, Super quality products and services.

The COB (chip on board) LED manufactured by Qiqi is comparable in product technology and R&D competitiveness to international companies. With the advantage of high cost performance, the establishment of the Shenzhen subsidiary has greatly improved the operational capabilities of Qiqi in the Mainland.

Qihao Optoelectronics' goal this year is to strengthen the LED lighting business in Mainland China, and to provide the most complete technical services to customers around the world based on the mainland. In the third and fourth quarters of 2012, more new ideas and products will be launched, taking advantage of the diversified and comprehensive product line to seize market opportunities.

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.
