ABSTRACT:
A method and apparatus for measuring sound velocity in a liquid, said method comprising the transmitting of a sound pulse or a group of sound pulses to the liquid to be measured and the measuring of the transit time of the sound pulse or the group of sound pulses in the liquid to be measured. To improve the accuracy of measurement, the sound pulse or the group of sound pulses is simultaneously transmitted with one and the same transmitter both to the liquid to be measured and to the reference material in which sound velocity is previously known. The sound pulse or the group of sound pulses arriving from the liquid to be measured and from the reference material is received and the time interval is measured with one and the same measuring means.
