G. Bucci et C. Landi, NUMERICAL-METHOD FOR TRANSIT-TIME MEASUREMENT IN ULTRASONIC SENSOR APPLICATIONS, IEEE transactions on instrumentation and measurement, 46(6), 1997, pp. 1241-1246
In this paper, the implementation of a novel algorithm for the measure
ment of the transit time is reported. It has been applied to implement
a smart, ultrasonic sensor for the fluid level measurement on a tank
by processing the detected signal. A prototype of an on-line operating
device, assembled to demonstrate the performance of the algorithm, is
also described. Simulation tests have been carried out to investigate
the algorithm performance, and we report on the results obtained. In
addition, the results obtained during the field testing and applicatio
n of the developed sensor are reported.
