ABSTRACT:
An acoustic current meter in which a CW burst is transmitted first in one direction along each acoustic path and then in the reverse direction along such path so that a single receiver system may be used and phase shift and/or d.c. offsets canceled. Four orthogonal components of current are measured so that the axis contaminated by the center support strut may be eliminated from further computation. A direction sensor includes a 3 axis magnetometer using feedback to minimize current requirements and a two axis accelerometer aligned therewith as a tilt sensor.
