MEASUREMENT OF ABSOLUTE TIME OF FLIGHT IN AN ULTRASONIC METER USING RECEIVED AND REFLECTED WAVES

MEASUREMENT OF ABSOLUTE TIME OF FLIGHT IN AN ULTRASONIC METER USING RECEIVED AND REFLECTED WAVES

A method and system for measuring a time of flight can involve correlating a signal comprising a reflected signal from a first transducer to a second transducer, or a subsequent reflected signal at the first transducer or the second transducer, with a previously received signal to produce a correlat...

Zusammenfassung:A method and system for measuring a time of flight can involve correlating a signal comprising a reflected signal from a first transducer to a second transducer, or a subsequent reflected signal at the first transducer or the second transducer, with a previously received signal to produce a correlation for a measurement of a time of flight. The signal(s) can include one or more of a pulse train, acoustic sound; ultrasonic sound; or light, and the previously received signal can be a signal that has been reflected one or more times.
