ULTRASONIC wavesNONDESTRUCTIVE testingTHEORY of wave motionDISTILLED waterThe phosphate content of a test sample is one of the indicators of the trophic status of the test water. In this work, an attempt was made to use a non-destructive ultrasonic technique to determine this parameter. ...
The ultrasonic wind speed and direction sensor uses the propagation speed of ultrasonic waves in the air to be affected by the air flow to measure wind speed. Compared with conventional anemometers, the biggest feature of this measurement method is that the entire wind measurement system does not...

Sonar is an advanced device that uses ultrasonic waves to measure the direction, distance, and speed of underwater objectssubmarinessubmarines; depth of sea; under water hills; valleys; sunken ships; etc. Print Page Previous Next Advertisements ...
A pulsed jet is generated by modulating a continuous stream of water by ultrasonic waves. A velocity transformer connected to a piezoelectric transducer is located axially inside a nozzle to induce longitudinal pulsations in the water. An extensive laboratory research program is in progress to ...
ultrasonic.Intensity,or loudness,is the strength of the pressure of these radiating waves and is measured in decibels.The human ear responds to intensity in a range from zero to 120 decibels.Any sound with pressure over 120 decibels is painful to the human ear.The speed of sound is generally...

5. Wind Gauge Anemometer vs. Ultrasonic Anemometer: Wind speed sensorsare commonly available in two main types: wind gauge anemometers and ultrasonic anemometers. Wind gauge anemometers are the traditional cup-and-vane design, while ultrasonic anemometers use ultrasonic sound waves to measure wind ...
