DV average price shocks drop at different price levels

DV average price oscillates down, different price levels focus on stability In November 2011, the price trend of China's digital video camera market and the proportion of products in various price segments were relatively stable. However, near the end of the year, it is expected that during the next three seasons of Christmas, New Year's Day and the Spring Festival, the digital camera market will usher in a new peak of sales and promotion, and the market price level will also fluctuate.

The average price of DV market fluctuates and shows a slight decline. The average price trend of China's digital camera market this month is relatively stable, ranging up and down within 400 yuan. In November, the average price of digital video cameras rose rapidly from the lowest value of 10019 yuan to around 10,200 yuan, followed by fluctuations. By the end of November, the average price of digital video camera products has dropped significantly, but it has remained above 10,000 yuan.

In addition, there have been fluctuations in the prices of several popular digital camcorder products such as the Sony HDR-XR160E, Sony HXR-MC1500C, new Sony NEX-VG20E kits (E 18-200mm), and Panasonic HDC-HS900GK. There were price cuts of different magnitudes; Sony's HDR-CX700E, Sony HDR-PJ50E, Sony HDR-CX180E, Panasonic HDC-MDH1GK, and other ten products showed price increases, and Sony HVR-Z5C's price increase reached 800 yuan.

Trends in the proportion of products with different price levels stabilizing trends In the Chinese digital video camera market this month, the proportion of products in different price segments has been relatively stable. In the entry price segment within 4000 yuan, the attention ratio of products within 2,000 yuan has risen slightly; the proportion of attention for 2001-4000 yuan products has fallen first and then rose. The proportion of users of 4001-7000 yuan high-end home-use digital video cameras and 700-110,000 yuan of high-end home-use digital video cameras are all concentrated at about 18.5%. The proportion of attention is very close, and the trend remains the same. The proportion of attention for products above 10,000 yuan is still quite high, and this month continues to rise slightly.

In addition, one thing worth paying attention to this month is that Canon released its first 4K digital camcorder product at the beginning of the month and it is also the first EOS series digital camcorder product. This product uses a Super 35-size CMOS sensor with a pixel size of 8.3M and a resolution of 3840×2160. Many well-known Canon EOS products have a high reputation in the area of ​​digital SLR cameras, and their EF lens also has a large amount of retention. The target group of this EOS digital camcorder is an independent producer. It also provides a more professional choice for many people keen to use the Canon EOS 5D Mark II for video shooting. At the same time, Canon also released five EF mount lenses and two PL mount lenses, reflecting Canon’s determination to enter the professional digital video market.

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.
