Ultrasonic Liquid Level Meter Using Linear Frequency Modulation Technique
When realizing the process control of modern industry such as chemistry, petroleum, metallurgy and water processing, we need to detect the liquid level in the container. The veracity and time are important to realizing the production safely and effectively. The existing ultrasonic liquid level meter systems make use of square pulse signal to work. Most [...]
Numerical Study on Delamination Detection in I-section Gfrp Beam with Optical Fiber-based Ultrasonic Technique
In recent years, pultruded section fiber-reinforced plastic (FRP) structures has been widely studied and used in many applications, due to its excellent performance and ease of production. However, the material’s heterogeneity and anisotropy is very easy to make the interface relative to failure, and resulting structure destruction.The traditional non-destructive technologies have many shortcomings because the [...]
Study on Boiler Temperature Field Rebuilding System in Coal Plant Based on ARM-Linux and Ultrasound
It is an important way to achieve safe and economic operation by on-line monitoring of boiler temperature field in coal power plant. The traditional contact-monitoring method has the disadvantages of short lifetime temperature measuring devices, high cost of replacement and long period of temperature measurement. Besides, in the traditional way of measuring, measuring object has [...]
Study on the Experimentation and Detection Characters of Ultrasonic Guided Waves in Cylindrical Structures
The pipe was distributed extremely abroad. The safe operation of pipe had a very close relationship with the life and production. It had a great important significance to ensuring the safe operation of pipe. The problems was gradually exposed in the operation of pipe, with the increase in the number of channels and the increase [...]
Study of Electroplating on Magnesium Alloy
Magnesium alloys are increasingly being utilized in fields such as automotive, power tools and computer industries on account of their excellent properties including low density,high strength-to-weight ratio, excellent imensional stability, high impact resistance and good thermal as well as electrical conductivity. However, poor corrosion resistance of magnesium restricts its engineering application.Enhancing the corrosion resistance by [...]
Study on Ultrasonic and Ozone Combined Cleaning Technology and Prototype Development
Fruit and vegetable, dish and other thing’s cleaning is an essential work of our daily life, developed countries have a lot of commercialization automatic cleaning equipment already, but usually do it by hand, wasting time and energy, and can’t guarantee the security of our diet. Our washing equipments are found to be poor in the [...]
