This technique is known as Sonomicrometry where the transit-time of the ultrasound signal is measured electronically (ie digitally) and converted mathematically to the distance between transducers assuming the speed of sound of the medium between the transducers is known. This elapsed time has relation to the level to be measured. Because ultrasonic sensors use sound rather than light for detection, they work in applications where photoelectric sensors may not. IMPULSE MEASUREMENT OF TRANSFER FUNCTIONS 3" " "" ...-. Span “D” should never extend to the blocking distance. We have therefore included an inductor in series just to achieve this feature for optimizing the transducers to their peak performance limits.
