Small dense spheres sink in water with a predictable velocity. A horizontal current deflects the path of sinking and the magnitude of the current can be determined from the horizontal deflection. This procedure can be used to measure very small currents, particularly those below 1 cmsec, which are too small to operate most current meters. A meter built to operate on this principle at sea is described. Author
