What are ultrasonic waves?
Ultrasonic flowmeters use ultrasonic sound waves that are beyond the frequency of what humans can hear. Most people can hear sound waves between 20 and 20.000 cycles per second, or hertz. Ultrasonic waves are sound waves above 20,000 cycles per second. Some animals hear and emit these sounds. For example, bats hear and emit ultrasonic sound waves that they use to hunt prey and for navigating. Moths can sense ultrasonic waves, which they use to detect predators. Ultrasonic waves are used to detect flaws in industrial parts, to explore the depths of the ocean, and to diagnose and treat diseases. How Ultrasonic Flowmeters Work Ultrasonic flowmeters are designed to work both in closed pipes and in open channels such as rivers or streams. For closed pipes, they work on both liquid and gas applications. Ultrasonic flowmeters work by sending an ultrasonic signal in the form of a wave from one side of the pipe to the other, and measuring the time it takes the signal to cross the pipe. The flow
By traveling through water with a frequency of 25-40 kHz, ultrasonic waves produce millions of microscopic air cavities loaded with vacuum energy. These air cavities, when getting in contact with surfaces, create a vacuum effect. The result is the quick separation of greases, carbons, chemicals, blood, particules from these surfaces. In the mean time, these surfaces are also cleaned from any bacteria or living organism. How to use EVYESONIK? The use of Evyesonik is very easy. The 3 buttons on the control panel control the 3 washing programs : dished (3 minutes), fruits&vegetables (5 minutes), desinfection (10 minutes). Before to use Evyesonik, the sink is filled with water, the products to be cleaned are placed in the special metallic baskets ordered within the system. At the end of the program, the system stops by itself. After the end of the program, the sink is emptied by removing the purge lid.
Ultrasound facial machine emits ultrasonic waves that are ideal for the skin. Ultraound wave has afrequency between 1 MHz to 3 MHz, which are not felt by during the usage. For the facial skin 1 Mhz is more than enough. Ultrasonic waves are high frequencies that give high-speed “massage” to the skin tissues. It gives your skin an exfoliating effect. This ultrasound facial machine promotes the lymph flow, helping lymph enter the gap between cells that blood vessels do not reach. This process greatly enhance the metabolism, which is essential to skin care.
