Using Ultrasonics to Measure Process Variables

open access: yesMeasurement + Control, 1990
Ultrasonics can be used in industrial processes to measure a number of variables. Liquid level can be determined by pulse-echo techniques. Flowrates can be measured by time-of-flight or doppler methods.

Ultrasound array transmitter architecture with high timing resolution using embedded phase-locked loops [PDF]

open access: yes, 2012
Coarse time quantization of delay profiles within ultrasound array systems can produce undesirable sidelobes in the radiated beam profile. The severity of these sidelobes is dependent upon the magnitude of phase quantization error - the deviation from ...
