Ultrasonic Circuits


An ultrasonic level or sensing system requires no contact with the target. For many processes in the medical, pharmaceutical, military and general industries this is an advantage over inline sensors that may contaminate the liquids inside a vessel or tube or that may be clogged by the product.

A common ultrasound application is an automatic door opener, where an ultrasonic sensor detects a person's approach and opens the door. Ultrasonic sensors are also used to detect intruders; the ultrasound can cover a wide area from a single point.

The flow in pipes or open channels can be measured by ultrasonic flowmeters, which measure the average velocity of flowing liquid. Ultrasonic Aplications includes motion sensors and flow measurements, non-destructive testings, ultrasonic range finders, ultrasound Identification (USID), imaging, acoustic microscopy, biomedical applications, ultrasonic cleaning, ultrasonic humidifiers, etc.
