ABSTRACT:
The invention concerns a method for measuring the displacement of a fluid in a conduit, by measuring the transit time of ultrasounds between two transducers (12, 13), in one direction and in the other, characterised in that it consists in: simultaneously exciting (16) both transducers; then simultaneously measuring (17, 18) the signals received on each of the transducers coming from the other transducer. The measured signals can then be digitised and correlated to determine the difference between the transit times. The invention enables to obtain faster and more reliable, measurement of transit times between transducers.
