ABSTRACT:
An apparatus for determining the transit times of ultrasonic pulses in a fluid has at least two electroacoustic converters (11, 20) arranged spaced apart in the fluid. An electrical signal proportional to the sound pressure generated at the transmitting converter (11) is derived from the transmitting converter (11) and is fed to the input of a correlation circuit (12).
