Abstract
A system on board which provides measurement of flow rates of a liquid layers at different depths, the provided results being corrected from error due to the craft movement, said system being proper for location and establishment of an underwater drilling site. In this system arrangement, are combined to cooperate a Doppler sonar system providing the craft speed with respect to the sea bottom and a flow rate meter system providing the liquid flow rate by reference to the craft, a common electro-acoustic transducers unit being switched for sequential operation from sonar to flow rate system and an output data processing system derives from these two measures the values of flow rate with respect to the sea bottom.
