how ultrasonic waves detect the air bubble
Asked by | 16th Feb, 2012, 09:09: PM
By far the most prevalent bubble sensing method.
Uses piezoelectric materials to create ultrasonic waves
Two main types:
Continuous: transmits a continuous ultrasonic wave and detects the drop in wave amplitude through air.
Pulsed Wave: transmits a pulsed wave and then detects both the amplitude and duration of the received wave to determine the medium.
?????The ultrasonic bubble sensor emits the ultrasounic wave into a fluid then senses wave reflected from the bubbles.
